निम्नलिखित में से कौन-सा शिक्षार्थियों में पठन विकसित करने का उद्देश्य नहीं है?
प्राथमिक स्तर पर भाषा शिक्षण का माध्यम क्या होना चाहिए?
दिशानिर्देश: नीचे दिए गए गद्यांश को ध्यानपूर्वक अध्ययन करे और इस पर आधारित प्रश्नो के उत्तर दे:
केंद्रीय माध्यमिक शिक्षा बोर्ड (सीबीएसई) 10वीं कक्षा के अच्छे परिणाम से जहां खुशी का संचार हुआ है, वहीं इससे अन्य छात्रों को बेहतर पढ़ाई की प्रेरणा भी मिली है। कुल 91.46 प्रतिशत छात्र परीक्षा में सफल हुए हैं। पिछले वर्ष की तुलना में इस बार 0.36 प्रतिशत बेहतर नतीजे रहे हैं। अब यह आश्चर्य की बात नहीं कि लड़कियों ने 93.31 के पास प्रतिशत के साथ लड़कों को पछाड़ दिया है। लड़कों के पास होने का प्रतिशत 90.14 रहा है। खास बात यह रही कि इस वर्ष 2.23 प्रतिशत या 41,804 छात्रों ने 95 प्रतिशत से अधिक अंक प्राप्त किए हैं। यह बहुत सकारात्मक बात है कि 18 लाख विद्यार्थियों के बीच 1.84 लाख से अधिक ने 90 प्रतिशत से अधिक अंक हासिल किए हैं। मोटे तौर पर यह कहा जा सकता है कि 10 में से एक विद्यार्थी को 90 प्रतिशत से अधिक अंक हासिल होने लगे हैं, यह कहीं न कहीं बेहतर होती शिक्षा की ओर एक इशारा है।
एक अच्छी बात यह रही है कि सीबीएसई ने कोरोना वायरस के कारण उत्पन्न परिस्थितियों को देखते हुए इस वर्ष 12वीं और 10वीं, दोनों कक्षाओं के टॉपरों का एलान नहीं किया है। शिक्षाविद भी मानते हैं कि टॉपरों के एलान से लाभ कम और नुकसान ज्यादा होते हैं। आज छात्रों के बीच चिंता का माहौल है, वे घरों में रहने को विवश हैं, उनमें अकेलापन, अवसाद और अन्य तरह की समस्याएं बढ़ी हैं। अत: आज शिक्षा बोर्ड को ऐसी कोई पहल नहीं करनी चाहिए कि छात्रों की बड़ी जमात में किसी तरह का असंतोष, दुख या अपमान पैदा हो। कोरोना के इस दौर में हमें यह भी ध्यान रखना चाहिए कि 10वीं की परीक्षा ढंग से नहीं हो पाई है। अनेक विषयों की परीक्षा कोरोना के कारण स्थगित करनी पड़ी है। परीक्षा फिर से लेने के प्रयास भी सफल नहीं रहे हैं। ऐसे में, विद्यार्थी जिन विषयों की परीक्षा नहीं दे पाए हैं, उनमें उन्हें आनुपातिक रूप से ही अंक दिए गए हैं। इसलिए यह कहना गलत नहीं होगा कि परिणाम संपूर्ण नहीं है। यदि कोई छात्र परीक्षा रद्द होने से पहले तीन से अधिक विषयों की परीक्षा दे चुका था, तो उसे तीन उच्चतम प्राप्त अंकों के हिसाब से बाकी विषयों में अंक दिए गए हैं। इस व्यवस्था में उन छात्रों के साथ अच्छा नहीं हुआ है, जो तीन से कम विषयों की परीक्षा दे पाए थे। ऐसे विद्यार्थियों के परिणाम की गणना में आंतरिक, व्यावहारिक और परियोजना मूल्यांकन के अंकों पर भी गौर किया गया है।
बेशक, परीक्षा परिणाम सामने हैं, लेकिन कामचलाऊ ही हैं। उम्मीद करनी चाहिए कि कोरोना काबू में आएगा और दोबारा इस तरीके से मूल्यांकन की जरूरत नहीं रह जाएगी। गुणवत्तापूर्ण शिक्षा के लिए भी सामान्य शिक्षा, परीक्षा और परिणाम की बहाली बहुत जरूरी है। फिर भी एनसीईआरटी और सीबीएसई जैसी संस्थाओं को ऑनलाइन परीक्षा के पुख्ता तरीकों पर भी काम करना होगा। आने वाले दिनों में जो परीक्षाएं होंगी, उनका ढांचा कैसा हो? कैसे विद्यार्थियों का सही मूल्यांकन हो सके? इसके पैमाने चाक-चौबंद करने होंगे। आगे शिक्षा की चुनौतियां बहुत बढ़ रही हैं। शिक्षा की गुणवत्ता बनाए रखने के लिए विशेष प्रयास करने ही होंगे। दसवीं और बारहवीं की अगली परीक्षाओं में अब छह-सात महीने ही बचे हैं। सुनिश्चित करना होगा कि आगामी परीक्षाओं में सफल विद्यार्थियों की संख्या में कोई कमी न आने पाए

बहुत दिनों बाद मुझे धूप ने बुलाया।
ताते जल नहा पहन श्वेत वसन आई,
खुले लॉन में बैठ गई दमकती लुनाई,
सूरज खरगोश धवल गोद उछल आया।
बहुत दिनों बाद मुझे धूप ने बुलाया।
नभ के उद्यान-छत्र तले भेज टीला,
पड़ा हरा फूल कढ़ा मेज़पोश पीला,
वृक्ष खुली पुस्तक हर पृष्ठ फड़फड़ाया।
बहुत दिनों बाद मुझे धूप ने बुलाया।
पैरों में मखमल की जूती सी क्यारी,
मेघ ऊन का गोला बुनती सुकुमारी,
डोलती सलाई हिलता जल लहराया।
बहुत दिनों बाद मुझे धूप ने बुलाया।
Q. कवि ने सूरज के लिए किस उपमान का प्रयोग किया है?
निर्देश: निम्नलिखित गद्यांश को पढ़कर दिए गये प्रश्नों के उत्तर दीजिए।
विज्ञान ने प्राचीन काल के ऋषियों-मुनियों और गुरूओं के मंत्रों और अस्त्रों के प्रयोग को आज विभिन्न प्रकार के आविष्कारों द्वारा सत्य कर दिया है। रामायण काल के पुष्पक विमान, वर्षा, अग्नि, वायु आदि की शक्तियों को प्रकट करने वाले बाणों, समुद्र सोख कर जमीन निकालने वाले मंत्र से चलने वाले अद्भुत बाण-अस्त्र, महाभारतकालीन संजय की प्राप्त हुई दिव्य-दृष्टि आदि को साक्षात् और सत्य करने के लिए विज्ञान ने हमें बहुत कुछ उपलब्ध करा दिया है।
मनुष्य विज्ञान की सहायता से शारीरिक कमज़ोरियों एवं स्वास्थ्य संबंधी समस्याओं से निजात पाने में सक्षम हो गया है। ऐसी असाध्य बीमारियों का इलाज भी संभव है, जिन्हें पहले लाइलाज समझा जाता था। अब टीबी सहित कैंसर जैसी खतरनाक बीमारियों को शुरुआती स्तर पर ही समाप्त करना संभव हो गया है।
विज्ञान का सहयोग मनुष्य के लिए एक अभिशाप के रूप में भी सामने आया है। विज्ञान की सहायता से मानव ने घातक हथियारों का आविष्कार किया तथा साथ ही मनुष्य ने अपने सुख-चैन के लिए अनेक प्रकार की मशीनों को भी आविष्कार किया, किंतु अफ़सोस की बात यह है कि मशीन के साथ-साथ वह भी मशीन होता जा रहा है, जिसके कारण उसकी जीवन-शैली भी अत्यंत व्यस्त हो गई है।
Q. ‘आविष्कार’ शब्द में निम्न में से कौन-सा उपसर्ग है?
Directions: Read the passage given below and answer the question that follows.
Once upon a time, there lived a sparrow in a tree. He was very happy to have a beautiful and comfortable nest of his own in the tree. The sparrow used to fly to far off places to pick at grains from so many fields, full of crops. At the Sun set, he would return to his perch. One day, the sparrow ate his fill, but could not return to his nest because of the heavy rains which continued for the whole night. The sparrow had to spend the whole night in a big banyan tree a little distance away from home.
The next morning, when the rain stopped and the sky became clear, the sparrow returned to his tree. He was astonished to find a rabbit occupying his beautiful and comfortable nest. The sparrow lost his temper and spoke to the rabbit, "It's my home you're sitting in. Please quit this place at once".
"Do not talk like a fool", replied the rabbit. "Trees, rivers and lakes do not belong to anyone. Places like these are yours only so long as you are living in. If someone else occupies it in your absence, it belongs to the new occupant. So, go away and do not disturb me anymore".
But, the sparrow was not satisfied with this illogical reply. He said, "Let's ask a person of wisdom and only then our case will be settled".
At a distance from the tree, there lived a wild cat. The cat, somehow, overheard the discussion that took place between the sparrow and the rabbit.
The cat immediately thought of a plan, took a holy dip in the river, and then sat like a priest and began chanting God's name in a loud tone. When the rabbit and the sparrow heard the cat chanting God's name, they approached him with a hope to get impartial justice and requested him to pass a judgement in the matter.
The cat became very happy to have both of them in front of him. He pretended to listen to their arguments. But, as soon as the right opportunity came, the cat pounced upon both of them and killed and ate them together with great relish.
(from Panchtantra)

Directions: Choose the appropriate word group for the underlined words in the given sentence.
My grandfather is 90 but he is as fit as a fiddle.
To which of the following categories does TV belong as a teaching aid?
Read the passage carefully and answer the questions that follow. Some words may be highlighted. Pay attention.
While the apprehension of losing job security is the most natural human tendency, there are some factors like technology that are beyond an individual's control. The sooner the employees embrace the truth, the easier it would be to convert it into an opportunity. This can be done by upgrading employee-skillset with the following skills for the requirement of future roles:
Leadership: The ability to lead the automation change will be a crucial skill in the organization. The leader will be also responsible for identifying the right talent in the machine age and engaging the workforce through human touch points.
Information Technology: Who can handle technology better than the technologists themselves? However, automation will force employees to hone their understanding of big data, machine learning, cloud computing, augmented reality, and mathematical and analytical skills. With the huge amount of data available, they should be able to apply it to present insight.
Management: The future workplaces will be a collaboration of machines/robots and humans. Hence, the managerial skills required to strike a balance between machines and human emotions, and making them work alongside will also come handy.
Soft Skills: Machines are after all machines. They may do work more quickly and efficiently, but they can't bring in 100 percent human touch and feel. There will be areas where people to people interaction, human relationships, and networking will still matter, hence soft skills such as communication, social and behavioural, cognitive and emotional intelligence would be expected from the employees.
It's about time that employees start reskilling/upgrading their skills and search for relevant programmes/courses in their organizations or outside. For example, IT major Capgemini is planning to train each of its one lakh employees in India in digital skills by 2018. Intel has launched 60 courses as a part of its 'AI Developer Education Programme' to train 15,000 Indian engineers, developers, scientists, and students.
It can't be denied that automation will impact the jobs considerably in India. However, developing people-centric skills and upgrading/reskilling for new roles could help employees tide over the automation wave.

Direction: Read the following passage and answer the questions given below.
Biodiversity for food and agriculture is among the earth’s most important resources. Crops, farm animals, aquatic organisms, forest trees, micro-organisms, and invertebrates – thousands of species and their genetic variability make up the web of biodiversity in ecosystems that the world’s food production depends on. Biodiversity is indispensable, be it insects pollinating plants, microscopic bacteria needed for making cheese, diverse breeds of livestock needed for living even in the harshest of environments, or the thousands of varieties of crops that sustain food security worldwide. For thousands of years, humankind has used, developed, and relied on biodiversity for food and agriculture. Biodiversity, and in particular genetic diversity, is being lost at an alarming rate. With the erosion of these resources, mankind loses the potential to adapt to new socio-economic and environmental conditions, such as population growth and climate change. Maintaining biodiversity for food and agriculture is a global responsibility. Risking biodiversity to man-made or other factors will always lead to an extremely large-scale famine of sheer magnitude. The FAO Commission on Genetic Resources for Food and Agriculture is an international forum that specifically deals with all components of biodiversity for sustaining food and agriculture.
The importance of agricultural biodiversity encompasses socio-cultural, economic, and environmental elements. All domesticated crops and animals result from the management of biodiversity, which is constantly responding to new challenges to maintain and increase productivity under constantly varying conditions and population pressures. Agricultural biodiversity is essential to satisfy basic human needs for food and livelihood security. Biodiversity, food, and nutrition interact on a number of key issues. It contributes directly to food security, nutrition, and well-being by providing a variety of plants and animals from domesticated and wild sources. Biodiversity can also serve as a safety net to vulnerable households relying on it during times of crisis, provide income opportunities to the rural poor, and sustain productive agricultural ecosystems. Coping mechanisms based on indigenous plants are particularly important for the most vulnerable people who have little access to formal employment, land, or market opportunities. Wild indigenous plants provide alternate sources of food when harvests fail.
Q. Agricultural biodiversity encompasses which of the following?
Which speaking activity is carried out in pairs or groups and often involve pupils asking and answering questions?

Nitu, a language learner, is finding certain topics taken up in class ‘difficult’. She is not able to understand the basic ideas and is also not able to handle the practice exercises or problems. Which one of the following is NOT the possible reason behind this challenge of teaching language?
Direction: Read the following information carefully and answer the given questions.
Initiatives such as “4 per mille” and Terraton aim to sequester huge amounts of carbon in the soil. The 2018 U.S. Farm Bill includes the first-ever incentives for farmers to adopt practices aimed at improving soil health and sequestering carbon. But these initiatives are missing a key point: not all soil carbon is the same.
The very different lifetimes of particulate organic matter and mineral-associated organic matter have important implications for these efforts. For example, adding low-quality crop residues to agricultural fields would likely create more particulate organic matter than mineral-associated organic matter. This could increase soil carbon in the short term - but if that field later is disturbed by tilling, a lot of it would decompose and the benefit would be quickly reversed. The best practices focus on building up the mineral-associated organic matter for longer-term carbon storage, while also producing high-quality particulate organic matter with lots of nitrogen to help boost crop productivity.
Natural healthy soils show us that providing continuous and diverse plant inputs that reach all the way to deep soil is key for achieving both high mineral-associated organic matter storage and particulate organic matter recycling. There are many promising ways to do this, such as maintaining plant cover on fields year-round; growing diverse crops that include high-nitrogen legumes and perennials with deep roots; and minimizing tillage.
However, not all soils can accumulate both mineral-associated organic matter and particulate organic matter. Before implementing any management practices for carbon sequestration, participants should first assess the carbon storage potential of the local soil, much as a doctor studies a patient before prescribing a cure. Sequestering soil carbon effectively requires an understanding of how particulate organic matter and mineral-associated organic matter work, how human actions affect them, and how to build up both types to meet our planet’s climate and food security needs.
Q. What conclusion can be drawn from the given passage?
