SECTION A
(Reading – 20 Marks)

Question 1.
Read the passage given below and answer the questions that follow: (8)
1. One day Gandhiji and Vallabhbhai Patel were talking in the Yeravda jail when Gandhiji remarked, “At times even a dead snake can be of use.” And he related the following story to illustrate his point: Once a snake entered the house of an old woman. The old woman was frightened and cried out for help. Hearing her, the neighbors rushed up and killed the snake. Then they returned to their homes. Instead of throwing the dead snake far away, the old woman flung it onto her roof.
2. Sometime later a kite flying overhead spotted the dead snake. In its beak, the kite had a pearl necklace which it had picked up from somewhere. It dropped the necklace and flew away with the dead snake. When the old woman saw a bright, shining object on her roof she pulled it down with a pole. Finding that it was a pearl necklace she danced with joy!
3. One day a bania found a snake in his house. He could not find anyone to kill it for him and had not the courage to kill it himself. Besides, he hated killing any living creature. So, he covered the snake with a pot and let it there.
4. As luck would have it, that night some thieves broke into the bania’s house. They entered the kitchen and saw the overturned pot. “Ah”, they thought, “the bania has hidden something valuable here.” As they lifted the pot, the snake struck. Having come with the object of stealing, they barely left with their lives.
5. Once he came out of jail, Gandhiji went from city to city, village to village collecting funds for the Charkha Sangh. During one of his tours, he addressed a meeting in Orissa.
6. After his speech a poor old woman got up. She was bent with age, her hair was grey and her clothes were in tatters. The volunteers tried to stop her, but she fought her way to the place where Gandhiji was sitting. “I must see him,” she insisted and going up to Gandhiji touched his feet.
7. Then from the folds of her sari, she brought out a copper coin and placed it at his feet. Gandhiji picked up the copper coin and put it away carefully.
8. The Charkha Sangh funds were under the charge of Jamnalal Bajaj. He asked Gandhi for the coin but Gandhi refused.

1.1. On the basis of your reading of the passage, answer any eight of the following questions in brief: (1 x 8 = 8)
(a) Why did the woman cry out?
(b) What did the kite do when it saw the dead snake on the roof?
(c) How did the live snake help the bania?
(d) Why was the old woman happy?
(e) Why did Gandhiji go to Orissa?
(f) Describe the woman who went up to meet Gandhiji.
(g) Why did the old woman have to fight her way to the place where Gandhiji was sitting?
(h) Who was in charge of the Charkha Sangh funds and what did he ask Gandhiji for?
(i) Find the word in paragraph 8 which is the Antonym of ‘Accepted’.

Question 2.
Read the passage given below and answer the questions that follow: (12)
1. The other day I received an unusual and very gratifying gift: I was given a tree or rather, I was given half-a-dozen trees which would be planted on my behalf. I had been invited to give a talk to an organization. After such events, the speaker is usually given a token gift. Sometimes the gift is that of a pen, or something useful. Often, the gift is in the form of a plaque or a similar token. However well-meant, such gifts are destined to gather dust in forgotten comers. Which is why I was agreeably surprised to be given a scroll which attested that, on a designated plantation established for the purpose, trees would be added in my name as part of the ‘green’ movement sponsored by the organization.
2. In an increasingly environmentally conscious world, the gift of a living tree or plant makes for a perfect present. The tradition of giving and receiving gifts has increasingly become a highly evolved marketing exercise. Apart from festivals like Diwali, Holi, Christmas, Eid and others, a whole new calendar of celebration events has been created to promote the giving of gifts: Mother’s Day, Father’s day, Teacher’s day, Valentine’s Day and so on.
3. What do you give to people – friends, relatives, spouses, children, parents, employees, clients, well-wishers who more or less have everything or at least everything that you could afford to give them as a gift?
4. Another box of chocolates? Another bottle of scent or after-shave? Another shirt or a kurta? Another another?
5. Thinking of unusual and pleasing presents which are also affordable is a full-time job. Like wedding planners and planners of theme parties, present planners—professionals who select and make up gift packages for you to give on occasions like marriages and corporate events— and doing increasingly good business.
6. However, the best-planned gifts of mine and thine go often awry. How often particularly during the so-called ‘festive seasons’ when gift giving and gift receiving reach epidemic proportions— have you had the embarrassing experience of getting back as a present a gift you yourself had given to someone who, having no use for it and not realizing that it was you who had gifted it, to begin with had unwittingly returned your gift to you? Like musical chairs, musical gifts only too often go round and round.
7. This is true not only at the individual but also at the level of the state. The diplomatic protocol also demands the exchange of gifts according to culture and tradition. Such tokens like the numbers of crudely made miniature Taj Mahals that Sarkari India has presented into the reluctant hands of foreign guests must fill entire godowns across the globe.
8. How much more preferable a living tree than a crude model of the Taj possibly made of marble from an unauthorized quarry? If the giving of tree sapling were to be institutionalized, it could lead to another green revolution in the lucrative and growing field of gift giving, with a new, eco-friendly industry taking root in plantations and nurseries specially created for the purpose. People could feel good looking at the certificate that trees had been planted in their names. Next birthday, give someone you love a tree one day the two of you might sit under the shade of the same tree.

2.1. On the basis of your reading of the passage, answer any four of the following questions in brief: (2 x 4 = 8)
(a) What was the gift? Why was it unusual and gratifying?
(b) Why is selecting a gift described as a ‘full-time job’?
(c) What does the writer mean by “However the best-planned gifts of mine and thine go often awry”?
(d) How can we cause another green revolution?
(e) What is a demand made by diplomatic protocol?

Sub: Stopping Child Labour

Sir,
Through the columns of your esteemed newspaper, I want to raise my voice against the exploitation of minors by the so-called elite class. They employ some boys and girls as full-time domestic help in order to save money. These children are given very less salary.
They have to work hard the whole day whereas the children of the employer enjoy all the luxuries of life and study in good schools. Sometimes the employers go to the extent of inflicting atrocities on these children. It is really painful to see that at this tender age these children are compelled to work under most unfavorable conditions.
Most of the time, parents of these children are responsible for their plight. Just to add the income of the family they drop their children from school and engage them in doing such a job. Our Government should take some concrete steps to improve the condition of these underprivileged children. I would like you to give appropriate space to my letter in your esteemed newspaper so that the authorities concerned wake up and take appropriate action.

Yours sincerely
Kunwar

Sub: Poor Broadband Service

Sir,
I am a customer of your reputed broadband service and my customer ID is 41721. The Internet service at my home is very poor and I have to restart the modem or adjust the cables 10-12 times to get it working every time. Even after that, it works only for 5-7 minutes and then the modem restarts itself.
I have already raised several complaints on the helpline number but the issue has not been rectified as yet. It seems that there is some hardware issue with modem and it needs replacement as it keeps on restarting and its indicators are also not in proper order.
I would highly appreciate if you would look into the matter to deliver the best to its customers.

Thanking you

Yours faithfully

Once a man named Mohanlal lived in a city. He and his wife had four sons. Both of them passed away, while the children were still young. Their greedy relatives tricked them out of their property and the boys were left penniless. One day the eldest brother said, “It seems to me that we should master some skills which will help us to earn a lot of money and be free.” After some discussion, they decided that it would be best if they acquired magic powers, which would help to bring in a steady income. They set off in different directions. Many months later, they met at appointed place.

The eldest son said, “I have mastered a particular kind of magic. I can cover the bare bones of an animal with the right kind of flesh.
The second one said, “I have learned to add skin and hairs of the animal after the flesh has been added to the bones. The third one said, “I know how to create the limbs of the animals whose bones have been clothed with skin, flesh, and hair. And the fourth one said, “When such an animal is fully formed, I can fill life into it.

So they went into the forest to look for the bones of an animal. Soon they found some scattered bones of an animal. The three brothers who knew to change showed their magic and they saw that they had made a lion. As soon as the fourth brother muttered a spell, the huge lion arose and ate each one of them. Thus, four brothers died because of foolish ideas. This proves if you lack wisdom and common sense even the best skills cannot help you.

In the beginning, the otter was neither hostile nor friendly. He was simply aloof and indifferent.
He preferred to sleep on the floor near the author’s bed. But soon he got familiar with the author and started taking a keen interest in his surroundings. The second night he came on to the author’s bed and slept in the crook of his knees. Thereafter he became friendly with the author. Whenever he was in trouble, he rushed to the author for protection. When he was indoors he spent most of the time in play. He even escaped to the bathroom where it struggled with tap for water. In this way, he became familiar with the author.

Answer 11.
Margot Frank is Anne’s elder sister. She is sixteen at the beginning of the diary and eighteen at the end of it. She does not get much attention in the diary, yet according to Anne, she is prettier, quieter, smarter and more matured than Anne. We do come across some minor quarrels between the two sisters but Margot is Anne’s wellwisher. She sees Anne as a friend to talk to and confide in. She even encourages Anne’s relationship with Peter. Still, she remains under-appreciated by Anne. Her moves in the diary depict her as a mature and caring person. Margot is docile and not assertive like Anne. She is more self-controlled though for Anne she is weak-willed and passive. Margot is quite intelligent and good at her studies. She is not at all jealous of Anne because she has not found a friend like her so much so, she even tells her sister that she thinks of Peter as a young brother. She is not impulsive and moody. She is not critical of other’s faults. She is closer to her mother. This can be the reason why she has been under-appreciated by Anne. She is of adjusting nature and accepts life as it is. She has not developed much like Anne.

The economic and social conditions worsened day by day during the war. Half a pound of coffee cost eighty guilders, half a pound of tea cost three hundred and fifty guilders and a pound of butter cost thirty-five guilders. Everyone was trading in the black market. People had to queue for vegetables and all kinds of goods. Vandalization, murders, and thefts were daily occurrences. The doctors could not visit the patients since their cars and bikes were stolen the moment they turned their back to them. The little children smashed the windows of people’s homes and stole whatever they could lay their hands on. People never left their homes in the fear of finding their belongings stolen. Even the police and night watchman were getting in on the act. Everyone wanted to put food into their stomachs and since wages had been frozen, people resolved to swindling. Everyday the newspapers were filled with reward notice for the return of stolen typewriters, prison rugs, etc. The electric clocks on street comers were dismantled and public phones were stripped down to the last wire. The police had been mightily trying to track down many girls of fifteen and older who were reported missing every day. The only good thing that came out of this was as the situation became more severe, the act of sabotage against the authorities increased.

Once Helen and Miss Sullivan were returning from a walk and they decided to rest under a wild cherry tree. They decided to have lunch sitting under the tree. Helen managed to climb the tree and found a seat in the branches. Miss Sullivan went away to the house to bring the lunch. Suddenly the sky was overcast with clouds and Helen could feel the difference in the atmosphere. She sensed the sky had turned dark as the sun’s warmth had dwindled. Helen smelt a strange odor coming up from the earth, the odor that preceded a thunderstorm. Helen was very frightened. She was alone, cut off from her friends and family and away from her teacher. Moreover, she wanted to get down from the tree. The tree shivered, the branches swayed and Helen held the branches very tightly. The twigs snapped and fell on Helen, the branches heaved and lashed. Helen had been driven to great fright when luckily her teacher arrived and was greatly delighted to feel the earth under her feet. That day Helen learned another lesson. She woke up to the fact that nature is not always kind and giving. It can be cruel and dangerous also. Beneath the softest touch were hidden treacherous claws.

Right from the beginning, the greatest credit of making Helen self-reliant went to Helen’s mother, who had been the epitome of encouragement and motivation. Helen noticed the entire world sitting in her mother’s lap. Her mother succeeded in making Helen understand a great deal. She learned to distinguish her clothes, do errands, make crude signs and feel all the objects. Her mother stressed on Helen’s strengths and did not complain about her deprivations. During Helen’s temperamental outbursts there was a great understanding on her part. Helen was never alienated. She was always there, within the family entertaining guests and making Christmas preparations. Helen’s mother never gave up hope for Helen’s education as she had read Dickens’ American Notes. She had read of the deaf and blind Laura Bridgman. Most of the family members doubted if Helen could ever be educated but her mother persisted in her efforts and finally, Miss Sullivan arrived at the doorstep. Helen’s mother never interfered with the innovative methods of Miss Sullivan’s teaching and provided all the support. She was a lady who could take a firm step also when things turned a little ugly at the Gilman school. Helen was immediately withdrawn. Helen’s mother tried every way to make Helen communicate. Helen’s mother remained her greatest strength and her greatest inspiration.

(b) मुंह का pH मान जब 5.5 से कम हो जाता है तो दांत की क्षति शुरू हो जाती है। भोजन के पश्चात् मुंह में बचे अथवा दांतों में फंसे भोजनकणों को जीवाणु अम्ल में परिवर्तित कर देते हैं। यह अम्ल दांतों को क्षति पहुँचाता है। दांत की क्षति को बचाने के लिए दांतों को टूथपेस्ट से नियमित रूप से साफ करना चाहिए। ये पेस्ट क्षारीय होते हैं, जो अम्ल के प्रभाव को उदासीन कर देते हैं।
(c) मधुमक्खी के काटने उसका डंक शरीर के उस भाग पर मेथेनोईक अम्ल छोड़ देता है, फलस्वरूप हमें जलन व पीड़ा महसूस होती है। परंतु उस जगह पर बेकिंग सोडा मलने पर जलन व पीड़ा समाप्त हो जाती है क्योंकि सोडा एक क्षारीय पदार्थ है, जो अम्ल को उदासीन कर उसके प्रभाव को समाप्त कर देता है।

उत्तर 8-
(a) केल्शियम की जल के साथ अभिक्रिया तेज नहीं है, इसलिए इस क्रिया में उत्पादित हाइड्रोजन गैस के अणु केल्शियम के अणुओं के साथ ही चिपक जाते हैं, जिसके कारण केल्शियम तैरने लगता है।
(b) अधिकतर धातु, HNO3 (नाइट्रिक) अम्ल के साथ अभिक्रिया करके H2 गैस नहीं बनाते हैं क्योंकि HNO3 अम्ल एक तीव्र ऑक्सीकारक पदार्थ है, जो कि H2 को H2O में ऑक्सीकृत कर देता है तथा स्वयं N2O, NO अथवा NO2 में अपचयित हो जाता है।

Time: 3 Hours
Maximum Marks: 80

General Instructions

  • The paper consists of 3 sections: A, B, C.
  • Attempt all the questions.
  • Don’t write anything on the question paper.
  • Read each question carefully and follow the given instructions.
  • All the answers must be correctly numbered and written in the answer sheet provided to you.
  • Strictly adhere to the word limit given in the question paper. Marks will be deducted for exceeding the word limit.
  • Ensure that questions of each section are answered together.

SECTION A
(Reading – 20 Marks)

Question 1.
Read the passage given below and answer the questions that follow: (8)

1. Dolphins are highly intelligent marine mammals and are part of the family of toothed whales that include orcas and pilot whales. They are found worldwide, mostly in shallow seas of the continental shelves, and are carnivores, mostly eating fish and squid. Dolphin coloration varies, but they are generally grey in color with darker backs than the rest of their bodies. Dolphins consume a variety of prey including fish, squid, and crustaceans.

2. It is difficult to estimate the population of dolphins since there are many different species spanning larger geographic area. Like bats, dolphins use echolocation to navigate and hunt, bouncing high pitched sounds of objects, and listening to the echoes. Most species lie in shallow areas of tropical and temperature oceans throughout the world. Five species live in the world’s rivers.

3. Dolphins are well known for their agility and playful behavior, making them a favorite of wildlife watchers. Many species will leap out of the water, spy-hop (rise vertically out of the water to view their surrounding) and follow ships, often synchronizing their movements with one another. Scientists believe that dolphins conserve energy by swimming alongside ships, a practice is known as bow-riding.

4. Dolphins live in social groups of five to several hundred. They use echolocation to find prey and often hunt together by surrounding a school of fish, trapping them and taking turns swimming through the school and catching fish. Dolphins will also follow seabirds, other whales and fishing boats to feed opportunistically on the fish they scare up or discard. To prevent drowning while sleeping only half of the dolphin’s brain goes to sleep while the other half remains awake so they can continue to breathe.

5. Dolphins are sometimes hunted in places like Japan, in an activity known as dolphin drive hunting. Besides drive hunting, they face threats from bycatch, habitat loss, and marine pollution. Dolphins have been depicted in various cultures worldwide. Dolphins occasionally feature in literature and film, as in the film series Free Willy. Dolphins are sometimes kept in ’ captivity and trained to perform tricks, but breeding success has been poor and the animals often die within a few months of capture. The most common dolphins kept are killer whales and bottlenose dolphins.

1.1. On the basis of your reading of the passage, answer any eight of the following questions in brief: (1 x 8 = 8)
(a) What do you mean by echolocation?
(b) Where are dolphins found?
(c) Why are dolphins favorite?
(d) Name two animals that use echolocation?
(e) How do dolphins hunt?
(f) What is drive hunting? What other threats do dolphins face?
(g) Name two types of dolphins given in the passage.
(h) How do dolphins conserve energy?
(i) Find the word in paragraph 5 which means the same as ‘represented’.

Question 2.
Read the passage given below and answer the questions that follow: (12)
1. Breathing is important for two reasons. It is the only means to supply our bodies and its various organs with oxygen which is vital for our survival. The second function of breathing is that it is one means it get rid of waste products and toxins from the body.

2. Oxygen is the most vital nutrient for our bodies. It is essential for the integrity of the brain, nerves, glands and internal organs. We can do without food for weeks and without water for days, but without oxygen, we will die within a few minutes. If the brain does not get proper supply of this essential nutrient, it will result in the degradation of all vital organs in the body.

3. The brain requires more oxygen than any other organ. If it does not get enough, the result is mental sluggishness, negative thoughts, and depression and, eventually, vision and hearing decline. Old people and those whose arteries are clogged often become senile and vague because oxygen to the brain is reduced. They get irritated very quickly.

4. Poor oxygen supply affects all parts of the body. The oxygen supply is reduced to all parts of the body as we get older due to poor lifestyle. Many people need reading glasses and suffer the hearing decline in old age.

5. When an acute circulation blockage deprives the heart of oxygen, a heart attack is a result. If this occurs to the brain, the result is a stroke.

6. For a long time, the lack of oxygen has been considered a major cause of cancer. Even as far back as 1947, work done in Germany showed that when oxygen was withdrawn, normal body cells could turn into cancer cells.

7. Similar research has been done with the disease. It showed that lack of oxygen is a major cause of heart disease, stroke, and cancer. The work done at Baylor University in the USA has shown that you can reverse arterial disease in monkeys by infusing oxygen into the diseased arteries.

8. Thus, oxygen is very critical to our well-being, and any effort to increase the supply of oxygen to our body and especially the brain will pay rich dividends. Yogis realized the vital importance of an adequate oxygen supply thousands of year ago. They developed and perfected various breathing techniques. These breathing exercises are particularly important for people who have sedentary jobs and spend most of the day in offices. Their brains are oxygen starved and their bodies are just ‘getting by’. They feel tired, nervous and irritable and are not very productive. On top of that, they sleep badly at night, so they get a bad start to the next day continuing the cycle. This situation also lowers their immune system, making them susceptible to catching colds, flu and other ‘bugs’.

2.1. On the basis of your reading of the passage, answer any four of the following questions in brief: (2 x 4 = 8)
(a) What is the significance of breathing?
(b) Why is oxygen important?
(c) What is the harmful effect of lack of oxygen?
(d) What yogis did, when they realized the importance of oxygen? For whom it is beneficial?
(e) What has been discovered at Baylor University in the USA?

2.2. On the basis of your reading of the passage, answer any four of the following: (1 x 4 = 4)

Answer 3.

Loss of Moral Values over Material Gains

Man’s incessant greed and lust for money have been the prime cause for the loss of moral values. Never content with what he has, he forever strives to amass money and material goods by any means. Nowadays people are primarily interested in the acquisition of money and status. The present-day world is highly materialistic and the ever increasing greed for money and matter at the cost of material has engulfed the society as a whole. There are very few who can claim that materialism has not affected him in any way. We are not complacent with the fulfillment of our basic needs but we want to acquire more and more by hook or by crook even if we have to jeopardize moral and ethical values. The mania of this excess money has squeezed humanistic approaches and has made us misanthropes, stoic, and egoistic in our efforts to fulfill this mania.

Answer 4.
It was the first time that Pooja was alone at home. Her parents would never leave her alone ever for a few hours. But one day there had been an emergency. Her grandfather had suddenly fallen ill and because of her school, Pooja’s mother had been very worried about Pooja as she had never left her alone. But Pooja assured her that she would be fine. Anyway, it was just for a day and night, as in the morning her aunt would reach home from Pune. Pooja spent the afternoon and evening playing on the computer and then finishing her homework. But with nightfall, all her coinage seemed to be disappearing. She first thought she would sleep with the light on but when she could not, she switched off. Pooja started getting frightened while tossing and turning on the bed. When she looked towards the window, her mind started conjuring up all sorts of shapes in the darkness. She told herself it was just a tree outside and nothing else but yet she was scared. Suddenly she heard a noise in the hall. Pooja was alarmed and thought of going and seeing from where the noise had come, but she could not get up from the bed. Finally, she got up and quickly switched on the light. She went into the hall and to her amusement and dismay, it was only her pet dog Jackie playing in the hall.

Once there lived a potter named Kabira in a village. He was planning and making arrangements for his son’s wedding, for which he planned to have a grand procession on the night of the wedding.
He wished to take his son and the bride on an elephant’s back around the village in a procession. Only one man named Sohanlal in the village had an elephant. Kabira asked him for borrowing his elephant. Sohanlal agreed. On the day of the wedding, the bride and the bridegroom went riding on the elephant. After the procession, when Kabira was taking the elephant back to Sohanlal’s house, the elephant suddenly fell down and died. Kabira was shocked and very sad. He rushed to Sohanlal and reported about the same. Kabira said that he would give the price of the elephant or another elephant. Mohanlal said that he only wanted his own elephant. The case was taken to a court where the judge also ordered Sohanlal to either accept the money or another elephant but he didn’t agree. The judge asked them to come the next morning. Then he called Kabira and said, “Don’t come to the court in the morning and stay in your house, keep your pots near the door and close it. I will ask Sohanlal to come to your house to call you. He will open the door in a hurry and all the pots will be broken.” The same thing happened. Now, Sohanlal said, “I will give you money or I will buy you new pots. At this Kabira disagreed. Sohanlal realized his mistake and went away without getting anything.

Answer 10.

Parenting

Parents should love their children unconditionally. A parent is someone who cuddles their children when they are going right in their lives because parents everywhere can say that if we as parents trust ourselves enough to trust our children, it will make parenthood easier. Parents know what their child’s requirements are and they train them to become independent in life. There is no need to teach anyone how to be a good parent. Even an illiterate mother knows how to take care of her children. But in today’s competitive world, raising a child is a very important task because it’s not always easy, it’s even harder if we do not have the consistent help if we are a single parent. Every good parent does not read parenting books, goes to parenting classes or had examples to learn more. In today’s world, it is better if the young adults are trained how to become better parents. This can help them to bring up their children by providing them with better nutrient food and care.

OR

Trustworthiness

Trust is one of the most important aspects of the relationship. Medicine cures the physical ailment of a person but trust and care help a person recover mentally. A trustworthy person will be dependable and honest with you. They will not lie, steal, cheat, lose devotion in something or turn their back on you over trivial matters. Integrity, honesty, reliability, and loyalty are easy ways to describe trustworthiness. Integrity is believing in yourself and standing up for what you believe in. Life will be difficult if there is no trust between husband and wife, parents and children, friends and neighbors, etc. When trust is lost it is irreparable. If trust is lost life may go on but the broken edge will always be visible. A trustworthy person is a valuable and reliable person.

According to Anne the best remedy for those who are afraid, lonely or unhappy is to go outside, somewhere where they can be quite alone with nature heavens and God. It is all this time only that one feels that all is as it should be and that God wishes to see people happy, amides nature’s simple beauty. As long as the sun shines, the cloudless skies exist, one cannot be unhappy. There will always be comfort and solace for every sorrow, whatever circumstances may be as one looks out of an open window, overall the roofs and on to the horizon. Anne firmly believes that nature brings solace in all troubles. She also feels that it would be long before she will be able to share this overwhelming feeling of blessing with someone who feels the way she does about it. Anne prefers to think about the beauty that exists in the world. Anne’s advice is to go outside, to the fields, enjoy nature and the sunshine, go out and try to recapture happiness in one’s self and in God. And to think of all the beauty that is still left in and around yourself and be happy. Anne’s diary is an amazing proof of a sensitive courageous girl. Her true spirit always appeared in every crisis. At every step, she pulled herself up and never gave up her goals, her ambition to live and be known as water.

Helen refers to examinations as the most annoying of her college life. Although she faced them many times and even cast them down yet they surfaced time and again. Helen feels that the days before these ordeals take place are spent in cramming one’s mind with mystic formulae and indigestible dates until one wishes that books and science were buried in the depths of the sea. And finally when the dreaded hour arrives the facts that one has garnered with so much of infinite trouble invariably fail one at the things one knows which are not there in an examination paper. When the proctor informs one that the time is up, it is with a feeling of intense disgust the one scribbles some rubbish in the paper and finally goes home. Helen had a tough time in overcoming these problems. Mr. Keeth had worked very hard and trained Helen to solve most of the problems mentally but the mode of examination upset all that. Nevertheless, Helen’s positive and die-hard approach made her win all the situations and rise above all the obstacles. Examinations killed the creativity and beauty of great books and one only tried to remember basic facts for exams so the appreciation of great work literature is lost.

SECTION A
(Reading – 20 Marks)

Question 1.
Read the passage given below and answer the questions that follow: (8)

1. So often these days we hear and speak of the conquest of Nature, ‘the taming of a river,’ ‘the war against insects,’ and so on. These phrases are often used without consciously attaching any value of them, but they have an underlying attitude of hostility towards Nature and Nature’s creatures, a viewpoint which seems to assume Nature as an enemy that needs to be vanquished. Alternatively, Nature is seen merely as a ‘resource’ to be ‘exploited’ – take the maximum out of it, regardless of what this does to the natural processes and to other creatures which depend on these processes. It is this attitude which views fellow human beings as a resource to be exploited, or other human communities as enemies to be conquered.

2. There is a growing lack of sensitivity and respect of our fellow creatures. This attitude is being drilled into a child by social forces, which can only be countered by environmental education. Yet, sadly, in most cases, this is not done. What is done is to talk about the food web and the energy cycles and ecological balance and how the removal of any elements disrupts the whole system, and how this can affect human beings too. What this approach lacks is the essential interaction with Nature and with other human beings. Indeed, in many environmental activities, the opposite takes place. A classic example of this is the making of a herbarium, or even worse, an insect collection, as common in both formal and non-formal education in India. A child is often encouraged to pluck leaves and flowers and run after butterflies with a net and is part of a large group of children similarly marauding a patch of nature. It is even worse when the activity is also competitive, that is, who collects the maximum. A lot of knowledge may be gained, but this knowledge emphasizes exploitation and conquest, not sensitivity and respect. Learning under a tree rather than in a classroom is far more effective and long lasting.

3. The alternative is to take up activities where ecological balance, ecological diversity, animal behavior, human plurality, and other such concepts and systems are introduced with the stress on their intrinsic worth. Materials, processes and living beings do not exist only for human use-they are worthwhile in themselves.

1.1. On the basis of your reading of the passage, answer any eight of the following questions in brief: (1 x 8 = 8)
(a) What does man’s attitude towards nature show?
(b) What is nature regarded as?
(c) How can environmental education be helpful?
(d) Which of these-leaming under a tree or in a classroom is more effective?
(e) What is man required to realize?
(f) Which type of knowledge emphasizes exploitation and conquest?
(g) What does ecological balance mean?
(h) How does a hostile attitude treat nature?
(i) Find the word in paragraph 2 which means the same as ‘communication’.

Question 2.
Read the passage given below and answer the questions that follow: (12)

1. Do children really need such long summer breaks, was a question posed by some experts recently? Apparently, such a long break disrupts their development and comes in the way of their learning process. Let’s get the takes back to their books, is perhaps the expert view, if not in so many words. One would have thought the children are doing too much during their vacations and not too little, given the plethora, of course, classes, camps and a workshop involving swimming, art, personality development, music, computers and the like that seem to cram their calendar. Even the trips taken in the name of holidays seem laden with exotic destinations and customized experience packed into a short period of time. We can do Europe in 10 days and Australia in a week and come back armed with digital memories and overflowing suitcase. Holidays are in some ways, no longer a break but an intensified search for experience not normally encountered in everyday life.

2. It is a far cry from summer holidays on experienced growing up. For holidays every year meant one thing and one thing alone- you went back to your native place, logging in with emotional headquarters of your extended family and spent two months with a gaggle of uncles, aunts and first and second cousins. The happiest memories of the childhood of a whole generation seem to be centered around this annual ritual of homecoming and of affirmation. We tendered tacit apologies for the separateness entailed in being individuals even as we scurried back into the cauldron of community and continuity represented by family. Summer vacation was a time sticky with oneness, as who we were and what we owned oozed out from our individual selves into a collective pot.

3. Summer was not really a break, but a joint. It was the bridge used to re-affirm one’s connectedness with one’s larger community. One did not travel, one returned. It was not an attempt to experience the new and the extraordinary but one that emphatically underlined the power of the old and the ordinary. As times change, what we seek from our summer breaks too has changed in fundamental ways. Today we are attached much more to the work and summer helps us temporarily detach from this new source of identity. We refuel our individual selves now, and do so with much more material than we did in the past. But for those who grew up in different times, summer was the best time for their lives. (Source: The Times of India)

Whenever crocodile visited the monkey he used to bring some gifts for him and the monkey also used to give him sweet fresh fruits from the tree on which he lived. They were very happy. One day it was stormy weather. Both of them were busy in their gossips. They did not know that such weather can be dangerous. The branch on which the monkey was sitting was very weak.

Answer 10.
Loss is an essential part of our life. We lose our very precious possessions – especially those precious gifts we received from our old friends or some of the valuable birthday gifts given by our parents. Some of these possessions may not be very expensive but a lot of memories are attached to them. A loss of a single paisa pierces us very much. Money is earned only after hard labour. We must understand its worth. It is no use to waste money over nothing. The poet desires that the boy should understand the nature of the loss. Hence when we lose any of those possessions we become very sad. One important lession we all need to learn is the fact that nothing is permanent in life. All things are subjected to loss, damage and decay. Hence we need to know how to cope with our losses. What is more important than all possessions is the fact that our life has to go on. This understanding will help us to cope with our loss in a better way.

Physical exercise has become important these days. It has a great medicinal value in our life. It keeps our body fit and free from various ailments. Exercise can help prevent excess weight.

We can do exercise in the form of doing all our household chores, by using the stairs instead of the elevator and walking short distances. Regular physical activity can help us prevent or manage a wide range of health problem. Physical exercise has a lot of advantages. It also builds our stamina and our muscles become strong. We do not need to set aside large chunks of time for exercise.

Answer 11.
Peter Van Daan was almost sixteen when he arrived in the Annexe. He is shy and awkward and unable to express himself. He cannot assert himself. Whenever he is snubbed, he hides himself in his room. He does nothing to improve his nature because he finds it easier not to make any effort. He gets easily influenced by others. Peter is lazy and has a weak character. He is hardly a person worth Anne’s notice. Anne needs a friend and when she finds him looking at her with longing, she starts having a soft comer for him. She finds him desperately in need of affection. Peter is simple minded. He talks about sexuality so nonchalantly that she quickly gets over her embarrassment. He thinks that he is stupid and all others very smart. Peter is a weak character and does not develop much in the two years he spent in the Annexe.
OR
The diary shows the gradual growth of Anne during her two years spent in the Annexe. From a teenaged girl who is curious about the changes taking place in her anatomy to an accepting young woman who is well aware of her duties and responsibility, the diary shows it all. Anne uses her diary to pour out her thoughts and feelings, her teenage physical longings for a companion and her ambitions in life. She justified her relationship with Peter and stands up to her father but in a matured manner by writing her feelings in a letter. She is dismayed over her father’s remark “Every child has to raise itself’. She feels that parents should only advise their children or point them in the right direction as ultimately children have to shape their own character. She says it was twice as hard for the young to hold on their opinions because ideas and virtues are being shattered everywhere.
Anne feels very strongly about the freedom of women and that women should get their due respect. When she looks at the sky, she is filled with hope.
OR
Helen describes the significance of the Hutton couple in her autobiography in glowing terms. The two years that Helen spent in New York were very important because she got the chance of meeting many famous people whose names she had often heard but never met. Helen was delighted to visit the lovely residence of Mr. and Mrs. Hutton, see their library, and read the beautiful sentiments, their gifted friends had written for them. Mr. Hutton was the kindest man and the most generous person, a good friend in all weathers.
Mrs. Hutton has often advised and helped Helen in her progress through college. When Helen felt discouraged, Mrs. Hutton wrote letters to her to inspire and encourage Helen. Helen always remembered her words “One painful duty fulfilled makes the next plainer and easier”. Mr. Hutton also introduced Helen to the famous writers like Mark Twain, Mr. William Dean Howells and Mr. Charles Dudley. Helen was greatly impressed by meeting such celebrities though she could not keep pace with their literary brilliance and style.
OR
When Helen was young, it had been Dr. Graham Bell’s recommendation to Helen’s parents to meet Mr. Anagnos which finally resulted in the arrival of Anne Sullivan in Helen’s life. Dr. Bell had been most sympathetic right from the beginning. Helen also visited the world fair with him and he introduced her to autophones and other inventions that made communications in the world easier. He went everywhere with Helen and described each object in the electrical world with great interest. These experiences matured Helen and she felt that she had taken a great leap from the world of the fairy tales to the real practical world. Dr. Bell had remained a sustaining influence in her life. Helen had spent many beautiful days at his home in Cape of Breton Island. Helen spent many delightful hours in his laboratory, listening to his experiments. She also helped him in flying kites to discover the laws that will govern future air-ships. Dr. Bell was the most proficient and he had a special manner of making everything look interesting. He was also poetic and humorous. He was most happy with the deaf children and his contribution in making life easy for the deprived peoples will be remembered for a long time by the world.

वे लक्षण, जो जनन कोशिकाओं के जीनों में परिवर्तन नहीं ला पाते हैं, वे लक्षण अगली पीढ़ी में नहीं जा सकते हैं। ऐसे लक्षणों को उपार्जित लक्षण कहते हैं।
उदाहरण के लिए :
(i) यदि किसी झींगुर को काफी दिनों से पर्याप्त भोजन न मिल पाए और इस कारण उसका वज़न घट जाए तो वज़न का घटना एक उपार्जित लक्षण है।
(ii) चूहे की कटी हुई पूंछ एक उपार्जित लक्षण है।
अथवा
एक पीढ़ी से दूसरी पीढ़ी तक प्रभावी लग DNA द्वारा स्थानांतरित होते हैं। उपार्जित लक्षण DNA में नहीं आते हैं अतः ये अगली पीढ़ी में वंशानुगत नहीं होते।
उदाहरण-जब मटर के एक शुद्ध लम्बे पौधे को एक बौने पौधे से संकरण करवाते हैं तो F, पीढ़ी के पौधे केवल लम्बे दिखाई देते हैं जबकि बौनेपन का लक्षण भी वंशानुगत होता है। जब F, पीढ़ी के पौधों का पुनः संकरण करवाते हैं, तो F, पीढ़ी में बौने पौधे भी दिखाई देते हैं। इससे पता चलता है कि बौनेपन का लक्षण भी वंशानुगत हुआ है।
अतः कहा जा सकता है, “ऐसा हो सकता है कि कोई लक्षण वंशानुगत हो जाए परन्तु व्यक्त न हो।”

उत्तर 14-

(iii) As the movement spread, foreign cloth was boycotted, and liquor shops were picketed. Peasants refused to pay revenue and chaukidari taxes, village officials resigned, and in many places forest people violated forest laws – going into Reserved Forests to collect wood and graze cattle.

Answer 20.
(i) It included the Alpine regions – the Tyrol, Austria and the Sudetenland – as well as Bohemia, where the aristocracy was predominantly German-speaking. It also included the Italian-speaking provinces of Lombardy and Venetia.

(ii) In Hungary, half of the population spoke Magyar while the other half spoke a variety of dialects. In Galicia, the aristocracy spoke Polish.

(iii) Besides these three dominant groups, there also lived within the boundaries of the empire, a mass of subject peasant peoples – Bohemians and Slovaks to the north, Slovenes in Camiola, Croats to the south, and Roumans to the east in Transylvania.

(iv) Such differences did not easily promote a sense of political unity. The only tie binding these diverse groups together was a common allegiance to the emperor.

OR

(i) The French began by building canals and draining lands in the Mekong delta to increase cultivation.

(ii) The vast system of irrigation works – canals and earthworks – built mainly with forced labour, increased rice production and allowed the export of rice to the international market.

(iii) Vietnam exported two-thirds of its rice production and by 1931 had become the third largest exporter of rice in the world.

(iv) This was followed by infrastructure projects to help transport goods for trade, move military garrisons and control the entire region. Construction of a trans-Indo-China rail network that would link the northern and southern parts of Vietnam and China was begun.

Answer 21.
(i) The literacy rate among women is only 54 per cent compared with 76 per cent among men. Similarly, a smaller proportion of girl students go for higher studies. But the girls drop out because parents prefer to spend their resources for their boys’ education rather than spending equally on their sons and daughters.

(ii) The proportion of women among the highly paid and valued jobs is still very small. On an average an Indian woman works one hour more than an average man every day. Yet much of her work is not paid and therefore often not valued.

(iii) The Equal Wages Act provides that equal wages should be paid to equal work. However in almost all areas of work, from sports and cinema, to factories and fields, women are paid less than men, even when both do exactly the same work.

(iv) In many parts of India, parents prefer to have sons and find ways to have the girl child aborted before she is bom. Such sex-selective abortion led to a decline in child sex ratio (number of girl children per thousand boys) in the country to merely 927. This ratio has fallen below 850 or even 800 in some places.

(v) There are reports of various kinds of harassment, exploitation and violence against women. They are not even safe even within their own home from beating, harassment and other forms of domestic violence.

Answer 22.
(i) Reforms through Legal Ways: Law has an important role to play in political reform. Carefully devised changes in law can help to discourage wrong political practices and encourage good ones. Example: A change in rules for LBW decisions helped to reduce negative batting tactics. But no one would ever think that the quality of cricket could be improved mainly through changes in the mles.

(ii) Any legal change must carefully look at what results it will have on politics. Sometimes the results may be counter-productive. Example: Many states have banned people who have more than two children from contesting panchayat elections. This has resulted in denial of democratic opportunity to many poor and women, which was not intended. Another example is RTI.

(iii) Reform through ‘Political Practices’: Democratic reforms are to be brought about principally through political practice. The most important concern should be to increase and improve the quality of political participation by ordinary citizens.

(iv) Reform measures that rely on democratic movements, citizens’ organisations and the media are likely to succeed in reforming political system. The main focus of political reforms should be on ways to strengthen democratic practices.

Answer 23.
(i) The government has launched a major road development project linking Delhi-Kolkata- Chennai-Mumbai and Delhi by six-lane Super Highways.

(ii) The North-South corridors linking Srinagar (Jammu & Kashmir) and Kanyakumari (Tamil Nadu), and East-West Corridor connecting Silcher (Assam) and Porbander (Gujarat) are part of this project.

(iii) The major objective of these Super Highways is to reduce the time and distance between the mega cities of India.

(iv) The National Highway Authority of India (NHAI) implements and maintains these super highways.

Answer 24.
Successful location: Mumbai, 1854

Factors responsible for location of cotton textile industry in Gujarat and Maharashtra:

(i) Availability of raw cotton: This region predominantly located in the black soil. Therefore, good quality of cotton was easily available.

(ii) Well developed transportation network: This region was well connected with efficient network of roads and railways. It got the benefit of port facilities also.

(iii) Market: There was a huge demand for cotton goods in and around this region. Therefore, this industry concentrated in and around Gujarat and Maharashtra.

Answer 25.
(i) Primary-Agricultural Sector

(ii) 370 million

(iii) Agricultural Sector is most important unorganised sector because the unorganised sector mostly comprises of landless agricultural labourers, small and marginal farmers. Nearly 80 per cent of rural households in India are in small and marginal farmer category. These farmers need to be supported through adequate facility for timely delivery of seeds, agricultural inputs, credit, storage facilities and marketing outlets. Employment is more production is less.

(iv) Tertiary Sector: Employment is less and production is less. Also it produces ‘services’ rather than ‘goods’.

Non-renewable resources are those which will get exhausted after years of use. We have a fixed stock on earth which cannot be replenished. Example: Crude oil.

Answer 7.
Removing barriers or restrictions set by the government in the economy is what is known as liberalisation.

Answer 8.
(i) In the nineteenth century, colonial India had become an exporter of agricultural goods and importer of manufactures. The depression immediately affected Indian trade. India’s exports and imports nearly halved between 1928 and 1934.

(ii) As international prices crashed, prices in India also plunged between 1928 and 1934 Peasants and farmers suffered more than urban dwellers. Though agricultural prices fell sharply, the colonial government refused to reduce revenue demands. Peasants producing for the world market were the worst hit.

(iii) For example, jute producers of Bengal suffered as the raw jute that was processed in factories for export in the form of gunny bags crashed, as gunny exports collapsed, the price of raw jute crashed more than expected.

(iv) Across India, peasants’ indebtedness increased. They used up their savings, mortgaged lands, and sold whatever jewellery and precious metals they had to meet their expenses. In these depression years, India became an exporter of precious metals, notably gold. The famous economist John Maynard Keynes thought that Indian gold exports promoted global economic recovery.

(v) The depression proved less grim for urban India. Because of falling prices, those with fixed incomes, town-dwelling landowners who received rents and middle-class salaried employees, now found themselves better off.

OR

(i) Cotton weavers in India faced two problems at the same time: their export market collapsed and the local market shrank, being glutted with Manchester imports. Produced by machines at lower costs, the imported cotton goods were so cheap that weavers could not easily compete with them.

(ii) By the 1850s, reports from most weaving regions of India narrated stories of decline and desolation. By the 1860s, weavers faced a new problem. They could not get sufficient supply of raw cotton of good quality.

(iii) When the American Civil War broke out and cotton supplies from the US were cut off, Britain turned to India. As raw cotton exports from India increased, the price of raw cotton shot up.

(iv) Weavers in India were starved of supplies and forced to buy raw cotton at exorbitant prices. In this, situation weaving could not pay. Then, by the end of the nineteenth century, weavers and other craftspeople faced yet another problem. Factories in India began production, flooding the market with machine-made goods.

OR

(i) At first, Bombay was the major outlet for cotton textiles from Gujarat.

(ii) Later, in the nineteenth century, the city functioned as a port through which large quantities of raw materials such as cotton and opium would pass.

(iii) Gradually, it also became an important administrative centre in western India, and then, by the end of the nineteenth century, a major industrial centre.

Answer 9.
Deeply grateful to print, Luther said, ‘Printing is the ultimate gift of God and the greatest one.’ (Compulsory point)

Reasons:
(i) In 1517, the religious reformer Martin Luther wrote Ninety Five Theses criticising many of the practices and rituals of the Roman Catholic Church. A printed copy of this was posted on a church door in Wittenberg.

(ii) It challenged the Church to debate his ideas. Luther’s writings were immediately reproduced in vast numbers and read widely.

(iii) This lead to a division within the Church and to the beginning of the Protestant Reformation. Luther’s translation of the New Testament sold 5,000 copies within a few weeks and a second edition appeared within three months.

(iv) Several scholars, in fact, think that print brought about a new intellectual atmosphere and helped spread the new ideas that led to the Reformation.

OR

(i) It was with the writing of Premchand that the Hindi novel achieved excellence. He began writing in Urdu and then shifted to Hindi, remaining an immensely influential writer in both languages. He drew on the traditional art of kissa-goi (storytelling).

(ii) Many critics think that his novel Sewasadan (The Abode of Service), published in 1916, lifted the Hindi novel from the realm of fantasy, moralising and simple entertainment to a serious reflection on the lives of ordinary people and social issues.

(iii) Sewasadan deals mainly with the poor condition of women in society. Issues like child marriage and dowry are woven into the story of the novel. It also tells us about the ways in which the Indian upper classes used whatever little opportunities they got from colonial authorities to govern themselves.

Answer 10.
The ethnic composition of this small country is very complex:

  1. Of the country’s total population, 59 per cent lives in the Flemish region and speaks Dutch language. Another 40 per cent people live in the Wallonia region and speak French. Remaining one per cent of the Belgians speak German.
  2. In the capital city Brussels, 80 per cent people speak French while 20 per cent are Dutch speaking.

Innovative Method: Any one of the Accommodation Methods OR simply write Accommodation OR Community Government.

Answer 11.
(i) If social differences cross cut one another, it is difficult to pit one group of people against the other. It means that groups that share a common interest on one issue are likely to be in different sides on a different issue.

(ii) Example: Consider the cases of Northern Ireland and the Netherlands. Both are predominantly Christian but divided between Catholics and Protestants. In Northern Ireland, class and religion overlap with each other. If you are Catholic, you are also more likely to be poor, and you may have suffered a history of discrimination. In the Netherlands, class and religion tend to cut across each other. Catholics and Protestants are about equally likely to be poor or rich.

(iii) The result is that Catholics and Protestants have had conflicts in Northern Ireland, while they do not do so in the Netherlands. Overlapping social differences create possibilities of deep social divisions and tensions. Cross-cutting social differences are easier to accommodate.

Answer 12.
Composition:
(i) Sri Lanka has a diverse population. The major social groups are the Sinhala-speakers (74 per cent) and the Tamil-speakers (18 per cent). Among Tamils there are two subgroups. Tamil natives of the country are called ‘Sri Lankan Tamils’ (13 per cent).

(ii) The rest, whose forefathers came from India as plantation workers during colonial period, are called ‘Indian Tamils’. As you can see from the map, Sri Lankan Tamils are concentrated in the north and east of the country.

(iii) Most of the Sinhala-speaking people are Buddhists, while most of the Tamils are Hindus or Muslims. There are about 7 per cent Christians, who are both Tamil and Sinhala.

Answer 13.

Regions/StatesRich inPoor/Deficient in
Amnachal PradeshAbundance of water resourcesLacks infrastructural development
RajasthanWell endowed with solar and wind energyLacks water resources
Cold desert of LadakhRich cultural heritageDeficient in water, infrastructure and some vital minerals.

Therefore, there is a need for balanced resource at the national, state, regional and local levels.

Answer 14.
Primitive subsistence farming is practised on small patches of land with the help of primitive tools like hoe, dao and digging sticks with family/community labour.

Characteristics :

  1. Farming depends upon monsoon
  2. Natural fertility of soil is used
  3. Slash and bum type of agriculture is followed by clearing a patch of land and after some time switching over to another land.

Answer 15.
It is because consumers have the right to be informed about the particulars of goods and services that they purchase. Consumers can then complain and ask for compensation or replacement if the product proves to be defective in any manner.

For example:

  1. If we buy a product and find it defective well within the expiry period, we can ask for a replacement. If the expiry period was not printed, the manufacturer would blame the shopkeeper and will not accept the responsibility. If people sell medicines that have expired severe action can be taken against them.
  2. Similarly, one can protest and complain if someone sells a good at more than the printed price on the packet. This is indicated by ‘MRP’  maximum retail price. In fact consumers can bargain with the seller to sell at less than the MRP.

Answer 16.

  1. Under COPRA, a three-tier quasijudicial machinery at the district, state and national levels was set up for redressal of consumer disputes.
  2. The district level court deals with the cases involving claims upto ₹ 20 lakhs, the state level courts between ₹ 20 lakhs and ₹ 1 crore and the national level court deals with cases involving claims exceeding ₹ 1 crore.
  3. If a case is dismissed in district level court, the consumer can also appeal in state and then in National level courts.

Thus, the Act has enabled us as consumers to have the right to represent in the consumer courts.

Answer 17.

  1. Rising competition
  2. Uncertain employment
  3. The condition of work and hardships of workers have become common to many industrial and service units in India. Even many organized sector have started to follow unorganized features.
  4. Several small scale industries have shut down due to competition which led to many workers jobless.

Answer 18.
(i) Higher cost of borrowing means a larger part of the earnings of the borrowers is used to repay the loan. Hence, borrowers have less income left for themselves. In certain cases, the high interest rate for borrowing can mean that the amount to be repaid is greater than the income of the borrower. This could lead to increasing debt and debt trap. Also, people who might wish to start an enterprise by borrowing may not do so because of the high cost of borrowing.

(ii) For these reasons, banks and cooperative societies need to lend more. This would lead to higher incomes and many people could then borrow cheaply for a variety of needs. They could grow crops, do business, set up small-scale industries etc. They could set up new industries or trade in goods. So cheap and affordable credit is crucial for the country’s development.

Answer 19.
(i) For plantation workers in Assam, freedom meant the right to move freely in and out of the confined space in which they were enclosed, and it meant retaining a link with the village from which they had come.

(ii) Under the Inland Emigration Act of 1859, plantation workers were not permitted to leave the tea gardens without permission, and in fact they were rarely given such permission.

(iii) When they heard of the Non-Cooperation Movement, thousands of workers defied the authorities, left the plantations and headed home. They believed that Gandhi Raj was coming and everyone would be given land in their own villages.

(iv) They, however, never reached their destination. Stranded on the way by a railway and steamer strike, they were caught by the police and brutally beaten up.

(v) They interpreted the term swaraj in their own ways, imagining it to be a time when all suffering and all troubles would be over. Yet, when the tribals chanted Gandhiji’s name and raised slogans demanding ‘Swatantra Bharat’, they were also emotionally relating to an all-India agitation.

(vi) When they acted in the name of Mahatma Gandhi, or linked their movement to that of the Congress, they were identifying with a movement which went beyond the limits of their immediate locality.

Answer 20.
German philosopher Johann Gottfried Herder (1744-1803) claimed that true German culture was to be discovered among the common people – das volk. He popularized true spirit of nation through folksongs, folk poetry and folk dance.

(i) Culture played an important role in creating the idea of the nation. Art and poetry, stories and music helped to express and shape nationalist feelings. Emotions, intuition and mystical feelings were not focused. Their effort was to shared collective heritage, a common cultural past, as the basis of a nation. They criticized the glorification of reason and science.

(ii) Examples:

  • German philosopher Johann Gottfried Herder
  • Karol Kurpinski

OR
(i) In 1926 a major protest erupted in the Saigon Native Girls School. A Vietnamese girl sitting in one of the front seats was asked to move to the back of the class and allow a local French student to occupy the front bench.

(ii) She refused. The principal, also a colon (French people in the colonies), expelled her. When angry students protested, they too were expelled, leading to a further spread of open protests.

(iii) Seeing the situation getting out of control, the government forced the school to take the students back.

(iv) The principal reluctantly agreed but warned the students, ‘I will crush all Vietnamese under my feet. Ah! You wish my deportation. Know well that I will leave only after I am assured Vietnamese no longer inhabit Cochinchina.’

Answer 21.

  1. Awareness
  2. mobilization for sharing opinions
  3. feeling for nation building
  4. Work for bringing social change
  5. Honesty in all spheres
  6. Accommodation of all differences

Answer 22.
(i) For a long time, the same party ruled both at the Centre and in most of the States. In those days, the Central Government would often misuse the Constitution to dismiss the State governments that were controlled by rival parties. This undermined the spirit of federalism.

(ii) All this changed significantly after 1990. This period saw the rise of regional political parties in many States of the country. This was also the beginning of the era of Coalition Governments at the Centre.

(iii) Since no single party got a clear majority in the Lok Sabha, the major national parties had to enter into an alliance with many parties including several regional parties to form a government at the Centre.

(iv) It led to a new culture of power sharing and respect for the autonomy of State Governments.

(v) This trend was supported by a major judgment of the Supreme Court that made it difficult for the Central Government to dismiss state governments in an arbitrary manner.

Answer 23.

Tin, copper, lead and zinc1. E.g. Coal, some forms of iron ore2.  E.g. Gypsum, potash and sodium salt

Answer 24.
This has been done by NTPC through the following:

  1. Optimum utilisation of equipment adopting latest techniques and upgrading existing equipment.
  2. Minimising waste generation by maximising ash utilization.
  3. Providing green belts for nurturing ecological balance and addressing the question of special purpose vehicle for afforestation.
  4. Reducing environmental pollution through ash pond management, ash water recycling system and liquid waste management.
  5. Ecological monitoring reviews and online database management for all its power stations.

Answer 25.
(i) SHG’s are a new source of providing loans to the rural poor particularly women. It may consist of 15-20 members belonging to a neighborhood who meet and save regularly. Their savings may vary from Rs 25 to Rs 100 or more depending on the ability to save. They provide loans to its members according to necessity.

(ii) The rate of interest charged by SHG’s is lesser than that charged by money lender. The SHG helps the borrowers overcome the problem of lack of collateral.

(iii) Small loans are provided to members for instance meeting working capital needs such as buying seeds, raw materials, fertilizers or cloth.

(iv) The group decides on the loans to be granted-the purpose, amount, interests to be charged, repayment schedule etc.

(v) The reason why banks are lending to these groups even without collateral is that in any case of non-repayment of loan, the members of the group seriously follow it up. They are the building blocks of organization of the rural poor. They also discuss certain social issues such as health, nutrition and domestic violence.
