खण्ड ‘क’ [20 अंक]
(पाठ्यपुस्तक व पूरक पाठ्यपुस्तक)

प्रश्न 1.
निम्नलिखित प्रश्नों के उत्तर लगभग 25-30 शब्दों में लिखिए। (2 x 4 = 8)
(क) ‘फादर कामिल बुल्के संकल्प से संन्यासी थे, मन से नहीं।’ लेखक के इस कथन के आधार पर सिद्ध कीजिए कि फ़ादर का जीवन परंपरागत संन्यासियों से किस प्रकार अलग था?
उत्तरः

  • संन्यासी के परंपरागत स्वरूप में मोह त्यागकर सामान्यतः समाज से पलायन कर जाने की प्रवृत्ति फ़ादर कामिल बुल्के द्वारा परंपरागत संन्यासी प्रवृत्ति से अलग नई परंपरा की स्थापना
  • कॉलेज में अध्ययन एवं अध्यापन…प्रियजनों के प्रति मोह, प्रेम व अपनत्व
  • प्रियजनों के घर समय-समय पर आना-जाना, संकट के समय सहानुभूति रख उन्हें धैर्य बँधाना आदि

फादर कामिल बुल्के ने परम्परागत संन्यासी की प्रवृत्ति को त्यागकर एक नई परंपरा स्थापित की। संन्यासी के परंपरागत स्वरूप में मोह को त्यागकर सामान्यतः समाज से पलायन करने की प्रवृत्ति होती है। फादर कामिल बुल्के ऐसे नहीं थे। वे एक बार जिससे रिश्ता बना लेते थे उसे जीवन भर निभाते भी थे। वे अपने प्रियजनों के घर पर समय-समय पर आते जाते थे व उनके संकट के समय उन्हें सहानुभूति व धैर्य बँधाते थे। इससे सिद्ध होता है कि फादर कामिल बुल्के संकल्प से संन्यासी थे, मन से नहीं।

(ख) फादर की उपस्थिति लेखक को देवदार की छाया के समान क्यों लगती थी? पाठ के आधार पर सिद्ध कीजिए।
उत्तरः

  • मानवीय गुणों से परिपूर्ण व्यक्तित्व व सबके लिए कल्याण की कामना ।
  • परम हितैषी के समान लोगों को आशीर्वचनों से सराबोर कर देना
  • भरपूर वात्सल्य से भरी नीली आँखों में तैरता अपनापन
  • उपर्युक्त कारणों से फ़ादर की उपस्थिति देवदार की छाया जैसी लगना

फादर मानवीय गुणों से ओतप्रोत थे। उनके मन में सबके लिए कल्याण की भावना थी। वे अपने परम हितैषी लोगों को अपने आशीर्वचनों से भर देते थे। उनकी नीली आँखों में सबके लिए सदा वात्सल्य का भाव तैरता रहता था। जिस प्रकार देवदार का वृक्ष अपनी छाया से पथिक को शीतलता का अहसास कराता है, उसी प्रकार फादर कामिल बुल्के अपनी बाँहों के घेरे में सदा सबको मातृत्व का अहसास कराते थे।

(ग) क्या सनक सकारात्मक भी हो सकती है? सकारात्मक सनक की जीवन में क्या भूमिका हो सकती है? सटीक उदाहरणों द्वारा अपने विचार प्रकट कीजिए।
उत्तरः

  • सनक अर्थात् धुन का पक्का होना, लगन, मेहनत तथा ईमानदारी से काम करने की सनक, सकारात्मक सनक
  • वैज्ञानिकों, महापुरुषों तथा समाज सेवियों के उदाहरण आज़ादी के मतवाले क्रांतिकारी, सामाजिक बुराइयों को समूल नष्ट करने की ठानने वाले समाज सुधारक
  • पहाड़ काटकर रास्ता बनाने वाले दशरथ माँझी जैसे सकारात्मक सनक वाले व्यक्तियों के उदाहरण…..

सनक का शाब्दिक अर्थ है धुन का पक्का होना अर्थात् लगन, मेहनत और ईमानदारी से अपने काम में लगे रहना। यदि सनक का परिणाम सबके हित में होता है तो वह सनक सकरात्मक होती है। आज़ादी के मतवाले क्रांतिकारियों ने देश को आजाद कराने में अपने प्राणों की बाज़ी लगा दी। पहाड़ को काटकर रास्ता बनाने वाले दशरथ माँझी की सनक ने आज हमारे सामने सकारात्मक परिणाम प्रस्तुत किया। अतः सनक सकारात्मक भी हो सकती है और इस प्रकार की सनक समाज के हित के लिए होती है।

(घ) ‘लखनवी’ अंदाज’ शीर्षक की सार्थकता तर्क सहित सिद्ध कीजिए।
उत्तरः

  • विषय वस्तु से शीर्षक के पूरी तरह मेल खाने में ही शीर्षक की सार्थकता
  • ‘लखनवी अंदाज़’ शीर्षक की कथानक से पूर्णतः संबद्धता
  • झूठी नवाबी शान, दिखावा, सनक, नज़ाकत आदि का वर्णन लेखक को दिखाने के लिए खीरे की फाँके सूंघकर खिड़की से बाहर फेंकने वाली घटना का उल्लेख आदि

“लखनवी अंदाज’ पाठ में नवाब साहब के माध्यम से झूठी शान, दिखावे और सनक का वर्णन किया गया है। किस तरह एक नवाब केवल दिखावे के लिए बिना खाए ही खीरे को फेंक देता है और उदर तृप्ति का दिखावा करता है। पाठ का शीर्षक विषयवस्तु से पूरी तरह मेल खाता है इसलिए पाठ का शीर्षक सार्थक है।

  • कविता समाज में क्रांति और उत्साह की भावना का संचार करने के उद्देश्यूपरक सृजन से प्रेरित बादल की गर्जना व क्रांति के माध्यम से लोगों के जीवन में उत्साह का संचार, प्रकृति में नव-जीवन का समावेश, क्रांति-चेतना का शंखनाद आदि शीर्षक की सार्थकता के आधार

‘उत्साह’ कविता एक आह्वान गीत है। कवि बादलों की गर्जना के माध्यम से निराश व हताश लोगों के जीवन में नवीन उत्साह का संचार करना चाहते हैं। यह कविता समाज में क्रांति और उत्साह की भावना का संचार करने के उद्देश्य से लिखी गई है। अतः कविता का शीर्षक सही है।

(ख) इस सत्र में पढ़ी गई किस कविता में फागुन के प्राकृतिक सौंदर्य का वर्णन किया गया है? उसे अपने शब्दों में व्यक्त कीजिए।
उत्तरः
निराला कृत ‘अट नहीं रही है’ कविता में चित्रित फागुन के अप्रतिम सौंदर्य की अपने शब्दों में कलात्मक अभिव्यक्ति

  • फागुन की सर्वव्यापक आभा एवं उसके अद्भुत सौंदर्य की व्यापकता का उल्लेख
  • प्रकृति में सौंदर्य व उल्लास का समावेश, कण-कण का फागुन के रंग में रंग जाना आदि

इस सत्र में पढ़ी गई महाकवि निराला की कविता ‘अट नहीं रही है’ कविता में फागुन के अप्रतिम सौंदर्य की कलात्मक अभिव्यक्ति की गई है। फागुन की आभा की सर्वव्यापकता ने प्रकृति को अद्भुत सौंदर्य से परिपूर्ण कर दिया है और वह कवि की आँखों में समा नहीं पा रहा है। पेड़-पौधे नव पल्लव और नव पुष्प से भर गए हैं। उनकी सुगंध धरती-आसमान को महका रही है। इस सौंदर्य ने मानव मन के साथ-साथ पशु-पक्षी को भी मुग्ध कर दिया है।

(ग) इस सत्र में पढ़ी गई किस कविता में कोरी भावुकता न होकर जीवन में संचित किए अनुभवों की अनिवार्य सीख है? कविता के नाम के साथ कथन की पुष्टि के लिए उपयुक्त तर्क भी प्रस्तुत कीजिए।
उत्तरः

  • ऋतुराज कृत ‘कन्यादान’ कविता…विदाई के समय माँ की केवल भावुकता का प्रदर्शन नहीं जीवन में संचित अनुभव पर आधारित उपदेश-सौंदर्य व वस्त्राभूषणों पर न रीझना, मानसिक रूप से दृढ़ बनना आदि
  • स्वयं को किसी के सामने लड़की जैसा न दिखाने आदि की व्यावहारिक सीख

कवि ऋतुराज द्वारा रचित कविता ‘कन्यादान’ में माँ द्वारा अपनी बेटी को उसके विवाह के अवसर पर केवल कोरी भावुकता में न जीते हुए जीवन में संचित किए गए अनुभवों को अपनाने की अनिवार्य सीख दी गई है। माँ ने बेटी को वस्त्रोंआभूषणों के कृत्रिम बंधन में न बंधने की सीख दी है। वह इन्हें केवल शाब्दिक भ्रम मानती हैं और उसे मानसिक रूप से दृढ़ बने रहने को कहती हैं। वह कहती है कि तुम्हें लड़की के समान मर्यादित जीवन तो जीना ही है पर अपने ऊपर होने वाले शोषण का विरोध भी करना है।

(घ) इस सत्र में पढ़ी गई किस कविता की अंतिम पंक्तियाँ आपको प्रभावित करती हैं और क्यों? तर्क सहित स्पष्ट कीजिए।
उत्तर

  • कन्यादान-‘आग रोटियाँ………जीवन के।।’
  • उत्साह-‘विकल-विकल………गरजो।।
  • अट नहीं रही है-‘कहीं पड़ी है…….पट नहीं रही है।।

इनमें से किसी एक कविता की उल्लिखित अंतिम काव्य-पंक्तियों के प्रभावित करने व प्रिय होने के कारणों का तर्क सहित उल्लेख

इस सत्र की पढ़ी गई कविताओं में से ‘कन्यादान’ कविता की अंतिम पंक्तियाँ ‘आग रोटियाँ सेंकने के लिए है जलने के लिए नहीं….’ ने मुझे सर्वाधिक प्रभावित किया है क्योंकि इन पंक्तियों से हमें यह सीख मिलती है कि ससुराल में सबका मानसम्मान करना है पर यदि हमारे ऊपर कोई अन्याय या अत्याचार हो तो हमें उसे चुपचाप रहकर सहना नहीं करना है बल्कि उसका विरोध करना है।

CBSE Sample Papers for Class 10 Hindi A Set 1 with Solutions

प्रश्न 3.
निम्नलिखित प्रश्नों में से किन्हीं दो प्रश्नों के उत्तर लगभग 50-60 शब्दों में लिखिए। (3 × 2 = 6)
(क) ‘माता का अंचल’ पाठ में वर्णित बचपन और आज के बचपन में क्या अंतर है? क्या इस अंतर का प्रभाव दोनों बचपनों के जीवन मूल्यों पर पड़ा है? तर्क सहित स्पष्ट कीजिए।
उत्तरः
खेल-खिलौनों व खेलने के स्थान में अंतर, पहले खेत-खलिहानों व खुले में खेलने की जगह बचपन का अब घर या अपने कमरे तक सीमित हो जाना पहले बचपन को संयुक्त परिवार का प्रेम व समय मिलना, अब एकल परिवार में कामकाजी माँ-बाप के जाने के बाद एकाकीपन पहले बड़ों के प्रेम के साथ-साथ संस्कार मिलना, अब माता-पिता की व्यस्तता से संस्कारों में गिरावट आना

यह पाठ काफी समय पहले लिखा हुआ है। उस समय और आज के समय के जीवन में दिन रात का अन्तर आ गया है। उस समय के बचपन में बच्चों पर पढ़ाई लिखाई का कोई दबाव नहीं था। सभी बच्चे मिलकर खूब खेलते थे किंतु अब आपस में स्नेह-भाव, विचारों का आदान-प्रदान व विश्वास की कमी हो गई है। आज के बच्चों की पढ़ाई के पाठ्यक्रम इतने मुश्किल हो गए हैं कि उन्हें पूरा करने में इतना समय लग जाता है

और उनके पास खेलने का समय ही नहीं बचता। आज के खेल की सामग्री व साधन भी बदल गए हैं। गली में नाटक खेलना, गिली मिट्टी के खिलौने बनाना, विवाह रचना, खेती करना आदि खेल नहीं रहे। पहले बचपन को संयुक्त परिवार का प्रेम व समय मिलता था पर अब एकल परिवार हो गए हैं और माँ-बाप के कामकाजी होने के कारण बच्चे को अकेले रहना पड़ता है और वह एकाकी हो जाता है। संयुक्त परिवार में रहकर उसे प्रेम और संस्कार मिलते थे पर आज एकाकी होने के कारण उसके संस्कारों में गिरावट आने लगी है।

(ख) ‘जॉर्ज पंचम की नाक’ पाठ में निहित व्यंग्य को स्पष्ट करते हुए बताइए कि मानसिक पराधीनता से मुक्ति पाना क्यों आवश्यक है?
उत्तरः

  • सत्ता से जुड़े लोगों का मानसिक पराधीनता का शिकार होना
  • सरकारी तंत्र में नीचे से ऊपर तक भ्रष्टाचार व्याप्त होना देश के सच्चे विकास व आम जनता के सच्चे सम्मान व स्वाभिमान की रक्षा के लिए मानसिक पराधीनता से मुक्ति पाना आवश्यक

‘जार्ज पंचम की नाक’ पाठ के आधार पर यह स्पष्ट है कि सादियों तक अंग्रेजों के पराधीन रहने के कारण आत्मसम्मान और स्वाबलंबन का भाव आज लुप्त हो गया है। पूरा सरकारी तंत्र अपनी अव्यवस्था, अयोग्यता और स्वार्थ सिद्धि के भाव को छिपाने के लिए चाटुकारिता को अपनाता है। सत्ता से जुड़ा हुआ प्रत्येक व्यक्ति मानसिक पराधीनता का शिकार है। ऊपर से नीचे तक सरकारी तंत्र में केवल भ्रष्टाचार का ही बोलबाला है। ऐसी स्थिति में देश का विकास संभव नहीं है। अतः देश के सच्चे विकास व आम जनता के सच्चे सम्मान व स्वभिमान की रक्षा के लिए मानसिक पराधीनता से मुक्ति पाना अत्यावश्यक है।

(ग) नदी, फूलों, वादियों और झरनों के स्वर्गिक सौंदर्य के बीच किन दृश्यों ने लेखिका के हृदय को झकझोर दिया? ‘साना-साना हाथ जोड़ि’ पाठ के आधार पर उत्तर दीजिए।
उत्तरः

  • आजीविका के लिए स्थानीय महिलाओं का अपनी पीठ पर बच्चे लादकर मार्ग बनाने के लिए पत्थर तोड़ने की विवशता
  • उस प्राकृतिक सौंदर्य के बीच भूख, दैन्य और जीवित रहने के लिए लड़ी जाने वाली – जीवन की जंग
  • संवेदनाओं को झकझोर देने वाली अनुभूति

प्राकृतिक सौंदर्य के अलौकिक आनंद में डूबी लेखिका का मन तब झकझोर उठा जब उन्होंने देखा। लेखिका ने देखा कि कुछ पहाड़ी औरतें पहाड़ों को तोड़ रही थी। यह बहुत जोखिम भरा कार्य था क्योंकि इन्हें कई बार डायनामाइट से भी करती हैं। उनके हाथों में हथौड़े-कुदाल देखकर ऐसा लेखिका ने कहा। वहीं दूसरी ओर पीठ पर डोको (बड़ी टोकरी) में उनके बच्चे भी बँधे थे, वह पत्ते बीन रही थी। जहां इतना सौंदर्य का प्रतिरूप था वहीं भूख, प्यास और आजीविका के लिए लड़ाई चल रही थी।

प्रश्न 4.
निम्नलिखित अनुच्छेदों में से किसी एक विषय पर दिए गए संकेत बिन्दुओं के आधार पर लगभग 150 शब्दों में एक अनुच्छेद लिखिए।
(क) कोरोना काल और ऑनलाइन पढ़ाई संकेत-बिन्दु-भूमिका, लॉकडाउन की घोषणा, ऑनलाइन कक्षाओं का आरंभ, इसके लाभ, ऑफ़लाइन कक्षाओं से तुलना, तकनीकी से जुड़ी बाधाएँ, निष्कर्ष
उत्तरः
दिए गए तीन अनुच्छेदों में से किसी एक विषय पर दिए गए संकेत-बिंदुओं के आधार पर लगभग 150 शब्दों में अनुच्छेद लेखन

  • भूमिका – 1 अंक
  • विषयवस्तु – 3 अंक
  • भाषा – 1 अंक

कोरोना काल और ऑनलाइन पढ़ाई कोरोना महामारी ने लोगों को स्वास्थ्य के दृष्टिकोण से ही प्रभावित नहीं किया बल्कि आर्थिक और मानसिक रूप से भी बहुत अधिक प्रभावित किया है। इस महामारी से निम्न और मध्यम-निम्न आय वाले देश अधिक प्रभावित हुए हैं। यहाँ की अर्थव्यस्था में बहुत गिरावट देखने को मिली है। देश में सम्पूर्ण लॉकडाउन लगने से स्कूल, कॉलेज और विश्वविद्यालयों को बंद रखा गया जिसके कारण छात्र जीवन बहुत प्रभावित हुआ। छात्रों को पढ़ाई में बहुत सी समस्याओं का सामना करना पड़ा और इस दौरान शिक्षा प्रणाली में असमानता और अधिक बढ़ी है।

ऑफलाइन कोचिंग संस्थान, स्कूल, कॉलेज और विश्वविद्यालय बंद होने के बाद ऑनलाइन शिक्षा व्यवस्था में तेजी से उछाल देखने को मिला । बहुत से ऐसे शिक्षण संस्थान थे जो कभी ऑनलाइन शिक्षा व्यवस्था से परिचित नहीं थे उन्होंने भी ऑनलाइन शिक्षा में कदम रखा और बहुत तेजी के साथ अपने आप को स्थापित करने में सफलता भी हासिल की। भारत सरकार ने कई तकनीकी संस्थानों के साथ मिलकर ऑनलाइन शिक्षा को बढ़ावा देने के लिए स्वयं, दीक्षा, इ-पाठशाला जैसे कई सारे पोर्टल विकसित किये ताकि एक गरीब छात्र भी आसानी से घर बैठे शिक्षा प्राप्त कर सके । यू-ट्यूब जैसे वीडियो शेयरिंग प्लेटफार्म पर भी बहुत सारे शिक्षकों ने फ्री में बच्चों को पढ़ाना शुरू किया ताकि छात्रों की शिक्षा पर इस कोरोना के प्रभाव को कम किया जा सके।

इस प्रकार अचानक से शिक्षा को ऑनलाइन रूप देना वास्तविक ऑनलाइन शिक्षा नहीं कहा जा सकता बल्कि इस प्रकार की शिक्षा को आपातकालीन ऑनलाइन शिक्षा कहना बेहतर होगा। क्योंकि इसके लिए पहले कोई अनुसंधान नहीं किया गया और बच्चों को बिना किसी तैयारी के ऑनलाइन शिक्षा को अपनाना पड़ा। ऑनलाइन शिक्षा कितनी भी गुणवत्ता पूर्ण क्यों न हो लेकिन ये कभी भी क्लास रूम से प्राप्त होने वाली शिक्षा का स्थान नहीं ले सकती। आज भी गाँवों में रहने वाले ऐसे बहुत से छात्र हैं जिनके पास मोबाइल और इंटरनेट की सुविधा नहीं है और परिवार की स्थिति भी इतनी अच्छी नहीं है कि उनको पढ़ाई करने के लिए मोबाइल फ़ोन दिला सके। ऐसे में शिक्षा में अमीर और गरीब बच्चों के बीच में बहुत असमानता देखने को मिली।

(ख) मानव और प्राकृतिक आपदाएँ संकेत-बिंदु-भूमिका, प्रकृति और मानव का नाता, मानव द्वारा बिना सोचे-विचारे प्रकृति का दोहन, कारण एवं प्रभाव, प्रकृति के रौद्र रूप के लिए दोषी कौन, निष्कर्ष
उत्तरः
मानव और प्राकृतिक आपदाएँ प्राचीन काल से, मनुष्य पृथ्वी के चेहरे पर विभिन्न प्रकार की प्राकृतिक आपदाओं के पीड़ित हैं। यह भूकंप, बाढ़, चक्रवात या ज्वालामुखीय विस्फोट हो, मनुष्यों ने हमेशा किसी भी प्राकृतिक आपदा का डर पाल रखा है। ऐसे डर के लिए प्राथमिक कारण का अनुमान लगाने में मुश्किल नहीं हैयह प्राकृतिक आपदाओं से निपटने में मानव की अक्षमता रही है। आज, हम अपने पूर्वजों से वैज्ञानिक और तकनीकी रूप से बेहतर हैं। विज्ञान में प्रगति ने वास्तव में कई आपदाओं की भविष्यवाणी करने में मदद की है और उनमें से कुछ को नियंत्रित करने के तरीकों को खोजा है।

हालांकि, आज भी प्राकृतिक आपदाओं से होने वाली क्षति बहुत बड़ी है। ऐसा क्यों है? क्या आधुनिक युग में प्राकृतिक आपदाएं अकेले प्राकृतिक बलों का परिणाम हैं? तकनीकी क्षमता का लापरवाही भरा उपयोग पर्यावरणीय गिरावट और इसके प्रतिकूल प्रभावों के लिए ज़िम्मेदार है। बड़े पैमाने पर खनन भूस्खलन को प्रेरित करता है। ऐसा प्रतीत होता है कि हम मनुष्यों को नुकसान पहुँचाने के बावजूद पारिस्थितिकीय गिरावट और प्राकृतिक आपदाओं के लिए जिम्मेदार हमारे कार्यों को सीमित करने में असमर्थ रहे हैं। कुछ हद तक, विज्ञान ने मनुष्यों को नुकसान की मात्रा सीमित करके प्राकृतिक आपदाओं से निपटने में मदद की है। प्राकृतिक आपदाएं न केवल भौतिक संपत्ति के नुकसान में बल्कि पीड़ितों को अत्यधिक शारीरिक और मानसिक पीड़ा का कारण बनती हैं।

तकनीकी और वैज्ञानिक विकास के कारण, आजकल प्राकृतिक आपदाओं की भविष्यवाणी की जा सकती है। उदाहरण के लिए, सिस्मोग्राफ की एक श्रृंखला, डेटा उत्पन्न कर सकती है जो प्रारंभिक चेतावनियां प्रदान करती है। प्राकृतिक आपदाएं भी अकेले नहीं आती हैं; ऐसी एक आपदा से खराब स्वच्छता, स्वास्थ्य और पुनर्वास कार्यों के कारण कई अन्य समस्याएं हो सकती हैं। मनुष्यों ने निश्चित रूप से उम्र बढ़ने से प्राकृतिक आपदाओं का सामना कैसे किया है, यहाँ तक कि उनके साथ कुछ हद तक सामना करना है। लेकिन अब भी प्रकृति का क्रोध वैज्ञानिक रूप से उन्नत और तकनीकी रूप से सुसज्जित मानव को एक व्यावहारिक गैर-इकाई के लिए कम कर सकता है।

(ग) सड़क सुरक्षाः जीवन रक्षा संकेत-बिंदु-भूमिका, सड़क सुरक्षा से जुड़े कुछ प्रमुख नियम, सड़क सुरक्षा के नियमों की अनदेखी से होने वाली हानियाँ, इन्हें अपनाने के लाभ, निष्कर्ष
उत्तरः
सड़क सुरक्षा : जीवन रक्षा
सभी सड़क सुरक्षा उपायों के प्रयोग द्वारा सड़क हादसों की रोक-थाम और बचाव है-सड़क सुरक्षा। सभी लोगों के लिये उनके पूरे जीवन भर सड़क सुरक्षा उपायों का अनुसरण करना बहुत ही अच्छा और सुरक्षित है। सभी को गाड़ी चलाते समय या पैदल चलते वक्त दूसरों का सम्मान करना चाहिये और उनकी सुरक्षा का ध्यान रखना चाहिये। सड़क किनारे हादसें, चोट और मृत्यु को टालने के लिये बहुत महत्वपूर्ण पहलूओं में से एक है

सड़क पर लोगों की सुरक्षा । दिनों-दिन सड़क पर गाड़ी चलाना असुरक्षित बनता जा रहा है। कई बार लोग लम्बे समय तक अपने निजी वाहनों को बिना किसी नियमित रख-रखाव और मरम्मत के रखते हैं, इसलिये ये बहुत जरूरी है कि समय से मरम्मत के साथ वाहनों की ठीक ढंग से कार्य करने की स्थिति के प्रति आश्वस्त रहें। ये केवल वाहन के जीवन को ही नहीं बढ़ाता है; हादसों को घटाने में भी मदद करता है। एक महत्वपूर्ण विषय के रूप में स्कूल में सड़क सुरक्षा उपायों को जरुर जोड़ना चाहिये जिससे चालन से पहले ही अपने शुरुआती समय में ही विद्यार्थीयों को इसके बारे में पूरी जानकारी प्राप्त हो सके। वाहनों के संचालन और उचित सड़क सुरक्षा उपायों के बारे में गलत जानकारी के कारण ज्यादातर सड़क हादसे होते हैं।

सभी सड़क समस्याओं से बचने के लिये निम्न सभी सड़क सुरक्षा उपाय बहुत मदद करते हैं। सड़क सुरक्षा के कुछ प्रभावकारी उपाय हैं जैसे वाहन के बारे में मूल जानकारी, मौसम और सड़क के हालात के अनुसार रक्षात्मक चालन, वाहन लाईटों और हॉर्न का प्रयोग, सीट पेटीका पहनना, वाहन शीशा का सही प्रयोग, अधिक-गति से बचना, रोड लाईट को समझना, सड़क पर दूसरे वाहनों से दूरी बना के रखना, परेशानी की स्थिति को संभालने की उचित समझ, टी.वी पर डॉक्यूमेंटरी जागरुकता का प्रसारण आदि।

आदरणीय चाचाजी,

सादर चरण स्पर्श
मैं यहाँ ठीक हूँ और आशा करता हूँ कि आप भी वहाँ ठीक होंगे। कल ही पिताजी का पत्र आया था जिसे पढ़कर पता चला कि आप दीदी की आगे की पढ़ाई छुड़वा रहे हैं और उनकी शादी करवा रहे हैं। चाचाजी, दीदी कॉलेज में दाखिला लेना चाहती हैं, वे आगे की पढ़ाई कर अपने पैरों पर खड़ी होना चाहती हैं। वे सिविल सर्विसेज में जाना चाहती हैं।

चाचाजी, आज जमाना बदल चुका है और हर क्षेत्र में लड़के-लड़कियाँ कंधे-से कन्धा मिलाकर चल रहे हैं। आज अन्तरिक्ष, विज्ञान, मेडिकल, खेल आदि कोई भी क्षेत्र ऐसा नहीं है जहाँ लड़कियों ने अपना परचम न फैला रखा हो। सायना नेहवाल, पी.वी. सिन्धु, कल्पना चावला आदि ऐसे अनेक नाम हैं जिन्होंने न केवल अपना बल्कि पूरे देश का नाम रोशन किया है। चाचाजी, आप देखिएगा कि वो दिन दूर नहीं जब आप भी दीदी पर गर्व अनुभव करेंगे।

आशा है कि आप मेरी बात समझ गए होंगे और दीदी की पढ़ाई जारी रखेंगे। आपको व चाचीजी को मेरा सादर चरण स्पर्श और छोटू को प्यार। आपका प्यारा राजेश

जयपुर विषय : अनाज की कालाबाजारी रोकने हेतु।

महोदय
नम्र निवेदन है कि मैं दुर्गापुरा क्षेत्र का निवासी हूँ। इस पत्र के माध्यम से मैं आपका ध्यान हमारे क्षेत्र में हो रही अनाज की कालाबाजारी की ओर आकर्षित करना चाहता हूँ। हमारे क्षेत्र में जो सरकारी राशन की दुकान है उसका संचालक गरीबों को मुफ्त अनाज का वितरण नहीं करता है। वह अनाज के बदले में उनसे पैसे माँगता है और विरोध करने पर उन्हें डराता-धमकाता है। गरीब व्यक्ति बड़ी मुश्किल से अपना जीवन-यापन करता है। उसके पास घर-खर्च में पैसे नहीं होते तो वह अनाज के पैसे कैसे देगा। दुकान का मालिक स्वयं मुनाफा कमाने के लिए अनाज को पास की दुकानों में ऊँची कीमत पर बेच देता है और गरीब बेचारा भूखा ही रह जाता है। ताकत के अभाव में बेचारा गरीब कुछ नहीं कर पाता। हमारी कॉलोनी के कुछ लोगों ने भी उसका विरोध करने का प्रयास किया पर सब व्यर्थ रहा ।।

मेरा आपसे निवेदन है कि आप अपनी टीम को निरीक्षण हेतु यहाँ भेजें ताकि राशन संचालक को उसकी गलती का अनुभव हो और कोई गरीब यहाँ से खाली हाथ न जाए।
आशा है कि आप इस ओर उचित कार्यवाही करेंगे। धन्यवाद।
प्रार्थी

Friction Class 8 Extra Questions and Answers Science Chapter 12

Question 35.
What do you mean by lubricants? What is their use?
Answer:
The substances which reduce friction are called lubricants. To increase efficiency, friction has to be reduced. This can be done by applying oil, grease or graphite in between the moving parts of a machine. Then its thin layer is formed there and moving surfaces do not directly rub against each other. In this way, interlocking of irregularities is avoided to a great extent and movement becomes smooth.

Question 36.
Site some examples when we prefer to reduce friction.
Answer:
Some examples where we prefer to reduce friction are :

Item used Used on Used for
(i) Fine powder Carrom board For easy movement of sticker.
(ii) Lubricants and air cushion Moving machine parts Reduce heat production and hence increasing efficiency. Also decreasing wear-tear rate.
(iii) Ball bearings Machine moving parts To convert sliding friction to rolling friction.

Question 37.
What are the different types of friction? Arrange them in the increasing order of their magnitude.
Answer:
Static friction: The friction which acts between the two surfaces in contact when there is not actual relative motion between the two surfaces. It is necessary for walking also because, without this static friction, feet would slip out, making it difficult to walk.

Sliding friction: The friction which acts between the two surfaces in contact when there is actual relative motion between the two surfaces. When we push a trunk and the trunk moves, the friction acting, in this case, is sliding friction. There is sliding friction between the brake pads and bike rims each time we use bike’s brakes. This friction slows the rolling wheels.

Rolling friction: The friction which acts between the two surfaces in contact when one surface rolls over the other surface. The friction in the ball bearings is rolling friction. Rolling friction is much weaker than sliding friction or static friction. This explains why most forms of ground transportation use wheels, including bicycles, cars, 4-wheelers, roller skates and scooters.

Rolling friction < Sliding friction < Static friction.

Answer:
The rain shadow is meant by the area which is the side, of the mountain not. getting enough rain. The winds after crossing the summits of the mountains descend along the slopes on the other side of the mountains. While descending they get warmed up and become dry.

There is one more reason that the moist winds do not cross over the other side of die mountains which are too high as in the case of the Himalayas which also render Tibet a dry region. This dry side of the mountain is called the leeward side and the rainless area on the leeward side is known as the rain shadow.

Question 22.
Discuss the reason why do the south-west monsoons give less rain in Tamil Nadu
Or
Why Chennai is dry even when it is raining heavily on the Malabar Coast in the month of July?
Or
Give the reasons why south-west. monsoons are less rainy in Tamil Nadu?
Answer:
Following are the reasons which cause Chennai keeping dry even when its raining heavily on the Malabar Coast in the month of July.

The Malabar Coast lies on the Western Ghats while Tamil Nadu or Chennai lies on the Eastern Ghats. In, the month of July when the monsoons arise from the Arabian sea and ‘first of all strike against the Western Ghats it rains heavily on the Malabar Coast.

Hence while leaving the Western Ghats these monsoons get almost deprived of their moisture. By the time they reach the Eastern ghats after covering a long distance, they cannot provide much-needed rain.

Question 24.
What kina climate is in Thiruvananthapuram?
Answer:
Thiruvananthapuram has an equal kind of climate; not, very cold or hot. the main reason for its equal climate is that it is situated on the seashore. Sea always keeps this place with a moderate climate. Again this place is situated on a hill. Heise it remains free from the hot climate of the temperate zone:

Question 25.
Why do the southwesterly winds cause rain in India?
Answer:
During the months of June- September, the South-West monsoon blow northward from the Arabian SeS and Bay of Bengal. These southwest winds cause rainfall almost in the whole of the northern India. These southwest monsoons blow from the oceanic high-pressure areas towards the low-pressure areas of land so they make heavy rainfall.

Question 26.
Discuss the distribution of precipitation in the country and the consequences of its uneven distribution.
Answer:
The distribution of precipitation in India is quite uneven:

  • Annual rainfall over 300, cm is received by the parts of western coast and north-eastern India. While western Rajsathan and. the adjoining parts of Gujrat, Haryana and Punjab receive rainfall even less than 50 cm.
  • The interior of the Deccan Plateau or the east of the Sahyadris also receives low rainfall.
  • The third area of low precipitation is around Leh in Kashmir.
  • Rest of the country receives moderate rainfall.
  • Himalayas region receives snowfall too.

Question 27.

The Arabian Sea branch of Monsoon’ strikes the Western Ghats and causes heavy- rains in Konkan and Malabar. It becomes comparatively dry when it reaches the Deccan Plateau and Madhya Pradesh. The branch of the Arabian Sea Monsoon passes over West Rajasthan and the Aravalli Hills.

Class 9 Geography Chapter 4 Extra Questions and Answers Climate

Question 28.
What is the reason that the rainfall decreases while going upward in the Ganga Valley but increases while going up the Indus. Valley?
or
How would you prove that the rainfall decreases while going eastward from West Bengal to Punjab?
Answer:
The monsoons rise both from the Bay of Bengal as well as from the Arabian Sea. The monsoons arriving from the Bay of Bengal cause heavy rainfall in the Brahmaputra Valley. Then because of the Himalayas, they take a Western turn and move up the Ganga Valley.

Here as they proceed westwards, become drier and drier and cause less and less rairi moving forward. It is the reason that Kolkata receives rainfall about 120cm, Patna 100, Allahabad 15 cm and Delhi about 56′ cm. Thus, moving upward the rainfall definitely decreases. It is the reason why Punjab gets less rain than West Bengal.

Question 29.
Discuss the factors controlling die Indian weather conditions.
Answer:
The main factors controlling the Indian weather conditions are the following:
1. Atmospheric Pressure: A big part of India lies in the area of north-east trade winds which are devoid of moisture and do not give fain. This is the reason that India has a quite long arid land. But the whole country is not arid.

During summer, the land of India gets heated more than its water parts. Because of this the low-pressure areas, develop over the interior vast landmass of Asia and high-pressure areas develop over the Indian ocean in the south: As the air moves from the high-pressure area to low pressure areas, the moisture-laden winds of the sea blow towards the landmass of Asia including India. These moisture-laden winds cause widespread rains in India in the summer season.

2. Upper Air Circulation: When the jet streams move eastwards, the Tibetan Highlands bifurcate them into two branches. The southern branch blow south of the Himalayas. This branch exercises an important effect on the winter weather in India.

3. Tropical Cyclones: The jet streams are attracted towards the. tropical depression in summer weather. These depressions attract the rain-bearing monsoons towards them and help in distribution of the monsoon rainfall over a large part of India.

4. The Western Disturbances: These are brought by the jet currents. When these disturbances enter India from west and north-west during winter they cause some rain in north-western parts of India. In the summer season, these jet currents move northwards and give place to an easterly jet stream which flow Over north India along 25°N.

Question 30.
Give an account of the hot weather season in India.
Answer:
It is a well-known fact that due to. apparent northward movement of the sun, the global heat belt shifts northward. Because of this fact from March to May, it is hot weather season in India. In March the highest day temperatures come around 38°C. This temperature is found in the Deccan Plateau. The temperature reaches around 42°C in Gujrat and Madhya Pradesh by April.

In fact temperatures, around 48°C are commonly found in the north-western part of the country in May. In peninsular India, these temperatures reveal the moderating influence of the Ocean.
The summer months experience rising temperature and falling air pressure in the northern part of the country.
A striking feature of the hot weather, season is the loo. The loo is meant by the strong, hot dry winds blowing during day over northern and northwestern India.

Sometimes they even continue until late in the evening. Direct exposure to these winds may even prove to be fatal. Dust storms are very common during the month of May in northern India. These storms bring temporary relief as they lower the temperature and may bring light rain and cool breeze.

This is also the season for localised thunderstorms, associated with violent winds, torrential downpours, often accompanied by hail. In West Bengal, these storms are known as the ‘Kaal Baisakhi: Towards the dose of the summer seasons, pre-monsoon showers are common especially, in Kerala and Karnataka. They help in the early ripening of mangoes, and are often referred to as ‘mango showers’.

Soil Class 7 Questions And Answers Question 17.
Write about soil erosion.
Answer:
The removal of fertile topsoil by water, wind or ice is known as erosion. Plant roots firmly bind the soil. In the absence of plants, soil becomes loose. So it can be moved by wind and flowing water. So, cutting of trees and deforestation should be prevented and efforts should be made to increase the green areas.

Chapter 9 Science Class 7 Extra Questions Question 18.
Discuss the dependence of crop on soil type.
Answer:
The climatic factors, as well as the components of soil, determine the various types of vegetation and crops that might grow in any region. Clayey and loamy soils are both suitable for growing cereals like wheat and gram. Such soils are good at retaining water. For paddy, soils rich in clay and organic matter and having a good capacity to retain water, are ideal.

For lentils (masoor) and other pulses, loamy soils, which drain water easily, are required. For cotton, sandy-loam or loam, which drain water easily and can hold plenty of air, are more suitable. Crops such as wheat are grown in the fine clayey soils because they are rich in humus and are very fertile.

  • Salim was able to obtain credit from the bank against some security. He got the loan, had bought the stocks and earning profit when he sold the stock.

Salim would be able to make profit year after year his business will expand.

Swapna took loan from the moneylender and paid a higher rate of interest. But what she bought for her farming expenses, she did not obtain the desired result. Unfortunately, her crop failed. She was caught up in debit. She had to pay to the moneylender a high amount in the form of interesct.

Question 23.
Why should the people deposit money with bank
Answer:
People hold money as deposit with the bank. At a point of time, people need only some currency for their day-to-day needs. For instance, workers who receive their salaries at the end of each month have extra cash at the beginning of the month.

They deposit it with the banks by opening a bank account in their name. Banks accept the deposits and also pay an interest rate on the deposits. In this way people’s money is safe with the banks and it earns an interest. People also have the provision to withdraw the money as and when they require. Since the deposits in the bank accounts can be withdrawn on demand, these deposits are called demand deposits.

Demand deposits offer another interesting facility. It is this facility which lends it the essential characteristics of money (that of a medium of exchange). One would like to make payments by cheques instead of cash. For payment through cheque, the payer who has an account with the bank makes out a cheque for a specific amount. A cheque is a paper instructing the bank to pay a specific amount from the person’s account to the person in whose name the cheque has been made.

Question 24.
What does the bank do with the deposits it has?
Answer:
Banks has the deposits from the people. It keeps only a small proportion of their deposits as cash with themselves. For example, banks in India these days hold about 15 per cent of their deposits as cash. This is kept as provision to pay the depositors who might come to withdraw money from the bank on any day. Since, on any particular day, only some of its many depositors come to withdraw cash, the bank is able to manage with this cash.

Banks use the major portion of the deposits to extend loans. There is a huge demand for loans for various economic activities banks make use of the deposits to meet the loan requirement of the people. In this way, banks mediate between those who a surplus funds (the depositors) and those who are in need these funds (the borrowers). Banks charge a higher interest rate on loans than what they offer on deposits. The difference between what is charge from borrowers and what is paid to depositors is their main source of income.

Question 25.
What do you mean by terms of credit? Why do the lender aks for collateral against loan?
Answer:

Class 10 Economics Chapter 3 Extra Questions and Answers Money and Credit 1

The Reserve Bank of India supervises the functioning of formal sources of loans. For instance, the banks maintain a minimum cash balance out of the deposits they receive. The RBI monitor that the banks actually maintain the cash balance.

Question 27.
Write a note on ‘Self Help Group’.
Answer:
In recent years, people have tried out some newer ways of providing loans to the poor. The idea is to organise rural poor, in particular women, into small Self Help Groups (SHGs) and pool (collect) their savings. A typical SHG has 15-20 members, usually belonging to one neighbourhood, who meet and save Regularly. Saving per member varies from ₹ 25 to ₹ 100 or more, depending on the ability of the people to save.

Members can take small loans from the group itself to meet their needs. The group charges interest on these loans but this is still less than what the moneylender charges. After a year or two, if the group is regular in savings, it becomes eligible for availing loan from the bank.

The SHGs help borrowers overcome the problem of lack of collateral. They can get timely loans for a variety of purposes and at a reasonable interest rate. Moreover, SHGs are the building blocks of organisation of the rural poor. Not only does it help women to become financially self-reliant, but the regular meetings of the group also provide a platform to discuss and act on a variety of social issues such as health, nutrition, domestic violence, etc.
