Directions for the following 4 (four) items:

Read the following four passages and answer the items that follow. Your answers to these items should be based on the passages only.

Passage-1

Global population was around 1.6 billion in 1990-today it is around 7.2 billion and growing. Recent estimates on population growth predict a global population of 9.6 billion in 2050 and 10.9 billion in 2100. Unlike Europe and North America, where only three to four per cent of population is engaged in agriculture, around 47 per cent of India's population is dependent upon agriculture. Even if India continues to do well in the service sector and the

 manufacturing sector picks up, it is expected that around 2030 when India overtakes China as the world's most populous country, nearly 42 per cent of India's population will still be predominantly dependent on agriculture.

 

7. Which of the following is the most logical and rational inference that can be made from the above passage?

(a) Prosperity of agriculture sector is of critical importance to India.

(b) Indian economy greatly depends on its agriculture.

(c) India should take strict measures to control its rapid population growth.

(d) India's farming communities should switch over to other occupations to improve their economic conditions.

Ans: A

Passage-2

Many pathogens that cause foodborne illnesses are unknown. Food contamination can occur at any stage from farm to plate. Since most cases of food poisoning go unreported, the true extent of global foodborne illnesses is

 unknown. Improvements in international monitoring have led to greater public awareness, yet the rapid globalization of food production increases consumers' vulnerability by making food harder to regulate and trace. "We have the world on our plates", says an official of WHO.

 

8. Which of the following is the most logical corollary to the above passage?

(a) With more options for food come more risks.

(b) Food processing is the source of all foodborne illnesses.

(c) We should depend on locally produced food only.

(d) Globalization of food production should be curtailed.

Ans: A

Passage-3

I am a scientist, privileged to be somebody who tries to understand nature using the tools of science. But it is also clear that there are some really

 important questions that science cannot really answer, such as: Why is there something instead of nothing? Why are we here? In those domains, I have found that faith provides a better path to answers. I find it oddly anachronistic that in today's culture there seems to be a widespread presumption that scientific and spiritual views are incompatible.

 

9. Which of the following is the most logical and rational inference that can be made from the above passage?

(a) It is the faith and not science that can finally solve all the problems of mankind.

(b) Science and faith can be mutually complementary if their proper domains are understood.

(c) There are some very fundamental questions which cannot be answered by either science or faith.

(d) In today's culture, scientific views are given more importance than spiritual views.

Ans: B

Passage 4

Though I have discarded much of past tradition and custom, and am anxious that India should rid herself of all shackles that bind and contain her and divide her people, and suppress vast numbers of them, and prevent the free development of the body and the spirit, though I seek all this, yet I do not

 wish to cut myself off from that past completely. I am proud of that great inheritance that has been and is, ours and I am conscious that I too, like all of us, am a link in that unbroken chain which goes back to the dawn of history in the immemorial past of India.

 

10. The author wants India to rid herself of certain past bonds because

(a) he is not able to see the relevance of the past

(b) there is not much to be proud of

(c) he is not interested in the history of India

(d) they obstruct her physical and spiritual growth

Ans: D

Directions for the following 4 (four) items:

Read the following passage and answer the four items that follow. Your answers to these items should be based on the passage only.

Passage

It is no longer enough for us to talk about providing for universal access to education. Making available schooling facilities is an essential prerequisite, but is insufficient to ensure that all children attend school and participate in the learning process. The school may be there, but children may not attend or they may drop out after a few months. Through school and social mapping, we must address the entire gamut of social, economic, cultural and indeed

 linguistic and pedagogic issues, factors that prevent children from weaker sections and disadvantaged groups, as also girls, from regularly attending and complementing elementary education. The focus must be on the poorest and most vulnerable since these groups are the most disempowered and at the greatest risk of violation or denial of their right to education.

 

The right to education goes beyond free and compulsory education to include quality education for all. Quality is an integral part of the right to education. If the education process lacks quality, children are being denied their right. The Right of Children to Free and Compulsory Education Act lays down that the curriculum should provide for learning through activities, exploration and discovery. This places an obligation on us to change our perception of children as passive receivers of knowledge, and to move beyond the

 convention of using textbooks as the basis of examinations. The teaching-learning process must become stress-free; and a massive programme for curricular reform should be initiated to provide for a child-friendly learning system, that is more relevant and empowering Teacher accountability systems and processes must ensure that children are learning, and that their right to learn in a child-friendly environment is not violated. Testing and assessment systems must be re-examined and redesigned to ensure that these do not force children to struggle between school and tuition centres, and bypass childhood.

 

17. According to the passage, which of the following is/are of paramount importance under the Right to Education?

1. Sending of children to school by all parents

2. Provision of adequate physical infrastructure in schools

3. Curricular reforms for developing child-friendly learning system

Select the correct answer using the code given below.

(a) 1 only

(b) 1 and 2 only

3. The Right to Education intends to take full advantage of demographic dividend.

Which of the above assumptions is/are valid?

(a) 1 only

(b) 2 and 3 only

(c) 3 only

(d) 1, 2 and 3

Ans: A

 

19. According to the passage, which one of the following is critical in bringing quality in education?

(d) Inculcating learning through activities and discovery

Ans: D

 

20. What is the essential message in this passage?

(a) The Right to Education now is a Fundamental Right.

(b) The Right to Education enables the children of poor and weaker sections of the society to attend schools.

(c) The Right to Free and Compulsory Education should include quality education for all.

(d) The Government as well as parents should ensure that all children attend schools.

Directions for the following 7 (seven) items:

Read the following four passages and answer the items that follow. Your answers to these items should be based on the passages only.

Passage-1

Desertification is a term used to explain a process of decline in the biological productivity of an ecosystem, leading to total loss of productivity. While this phenomenon is often linked to the arid, semi-arid and sub-humid ecosystems, even in the humid tropics, the impact could be most dramatic. Impoverishment of human-impacted terrestrial ecosystems may exhibit itself

 in a variety of ways: accelerated erosion as in the mountain regions of the country, salinization of land as in the semi-arid and arid 'green revolution' areas of the country, e.g., Haryana and western Uttar Pradesh. and site quality decline a common phenomenon due to general decline in tree cover and monotonous monoculture of rice/wheat across the Indian plains. A major consequence of deforestation is that it relates to adverse alterations in the hydrology and related soil and nutrient losses. The consequences of deforestation invariably arise out of site degradation through erosive losses. Tropical Asia, Africa and South America have the highest levels of erosion. The already high rates for the tropics are increasing at an alarming rate (e.g.,

 through the major river systems-Ganga and Brahmaputra, in the Indian context), due to deforestation and ill-suited land management practices subsequent to forest clearing. In the mountain context, the declining moisture retention of the mountain soils, drying up of the underground springs and smaller rivers in the Himalayan region could be attributed to drastic changes in the forest cover. An indirect consequence is drastic alteration in the upland-lowland interaction, mediated through water. The current concern the tea planter of Assam has is about the damage to tea plantations due to frequent inundation along the flood-plains of Brahmaputra, and the damage to tea

 plantation and the consequent loss in tea productivity is due to rising level of the river bottom because of siltation and the changing course of the river system. The ultimate consequences of site desertification are soil degradation, alteration in available water and its quality, and the consequent decline in food, fodder and fuel-wood yields essential for the economic well-being of rural communities.

 

27. According to the passage, which of the following are the consequences of decline in forest cover?

1. Loss of topsoil

2. Loss of smaller rivers

3. Adverse effect on agricultural production

4. Declining of groundwater

Select the correct answer using the code given below.

(a) 1, 2 and 3 only

(b) 2, 3 and 4 only

(c) 1 and 4 only

(d) 1, 2, 3 and 4

Ans: D

 

28. Which of the following is/are the correct inference/inferences that can be made from the passage?

1. Deforestation can cause changes in the course of rivers.

2. Salinization of land takes place due to human activities only.

3. Intense monoculture practice in plains is a major reason for desertification in Tropical Asia, Africa and South America.

Select the correct answer using the code given below.

(a) 1 only

(b) 1 and 2 only

(c) 2 and 3 only

(d) None of the above is a correct inference

Ans: A

 

29. With reference to desertification', as described in the passage, the following assumptions have been made :

2. Deforestation invariably leads to floods and desertification.

Which of the above assumptions is/are valid?

(a) 1 only

(b) 2 only

(c) Both 1 and 2

(d) Neither 1 nor 2

Ans: D

Passage-2

A diversity of natural assets will be needed to cope with climate change and ensure productive agriculture, forestry, and fisheries. For example, crop varieties are needed that perform well under drought, heat, and enhanced CO. But the private-sector and farmer led process of choosing crops favours homogeneity adapted to past or current conditions, not varieties capable of producing consistently high yields in warmer, wetter, or drier conditions.

 Accelerated breeding programmes are needed to conserve a wider pool of genetic resources of existing crops, breeds, and their wild relatives. Relatively intact ecosystems, such as forested catchments, mangroves, wetlands, can buffer the impacts of climate change. Under a changing climate, these ecosystems are themselves at risk, and management approaches will need to be more proactive and adaptive. Connections between natural areas, such as

 migration corridors, may be needed to facilitate species movements to keep up with the change in climate.

 

30. With reference to the above passage, which of the following would assist us in coping with the climate change?

1. Conservation of natural water sources

2. Conservation of wider gene pool

3. Existing crop management practices

4. Migration corridors

Select the correct answer using the code given below.

(a) 1, 2 and 3 only

(b) 1, 2 and 4 only

(c) 3 and 4 only

(d) 1, 2, 3 and 4

Ans: B

 

31. With reference to the above passage, the following assumptions have been made:

1. Diversification of livelihoods acts as a coping strategy for climate change.

2. Adoption of monocropping practice leads to the extinction of plant varieties and their wild relatives.

Which of the above assumptions is/are valid?

(a) 1 only

(b) 2 only

(c) Both 1 and 2

(d) Neither 1 nor 2

Ans: C

Passage-3

Today, the top environmental challenge is a combination of people and their aspirations. If the aspirations are use like the frugal ones we had after the Second World War, a lot more is possible than if we view the planet as a giant shopping mall. We need to get beyond the fascination with glitter and understand that the planet works as a biological system.

 

32. Which of the following is the most crucial and logical inference that can be made from the above passage?

(a) The Earth can meet only the basic needs of humans for food, clothing and shelter.

(b) The only way to meet environmental challenge is to limit human population.

(c) Reducing our consumerism is very much in our own interest.

(d) Knowledge of biological systems can only help us save this planet.

Ans: C

Рassage-4

Some people believe that leadership is a quality which you have at birth or not at all. This theory is false, for the art of leadership can be acquired and can indeed be taught. This discovery is made in time of war and the results achieved can surprise even the instructors. Faced with the alternatives of

 going left or right, every soldier soon grasps that a prompt decision either way is better than an endless discussion. A firm choice of direction has an even chance of being right while to do nothing will be almost certainly wrong.

 

33. The author of the passage holds the view that

(a) leadership can be taught through war experience only

(b) leadership can be acquired as well as taught

(c) the results of training show that more people acquire leadership than are expected

(d) despite rigorous instruction, very few leaders are produced

Directions for the following 8 (eight) items:

Read the following eight passages and answer the items that follow. Your answers to these items should be based on the passages only.

Passage-1

All actions to address climate change ultimately involve costs. Funding in vital in under countries like India to design and implement adaptation and mitigation plans and projects. The problem is more severe for developing

 countries like India, which would be one of the hardest hit by climate change, given its need to finance development. Most countries do indeed treat climate change as real threat and are striving to address it in a more comprehensive and integrated manner with the limited resources at their disposal.

 

49. With reference to the above passage, the following assumptions have been made

1. Climate change is not a challenge for developed countries.

2. Climate change is a complex policy issue and also a development issue for many countries.

3. Ways and means of finance must be found to enable developing countries to enhance their adaptive capacity.

Which of the above assumptions is/are valid?

(a) 1 and 2 only

(b) 3 only

(c) 2 and 3 only

(d) 1, 2 and 3

Ans: C

Passage-2

Cooking with biomass and coal in India is now recognized to cause major health problems, with women and children in poor populations facing the greatest risk. There are more than 10 lakh premature deaths each year from household air pollution due to polluting cooking fuels with another 1.5 lakh

 due to their contribution to general outdoor air pollution in the country. Although the fraction of the Indian population using clean cooking fuels, such as LPG, natural gas and electricity, is slowly rising, the number using polluting solid fuels as their primary cooking fuel has remained static for nearly 30 years at about 70 crore.

 

50. Which of the following is the most crucial and logical inference that can be made from the above passage?

(a) Rural people are giving up the use of polluting solid fuels due to their increasing awareness of health hazards.

(b) Subsidizing the use of clean cooking fuels will solve the problem of India's indoor air pollution.

(c) India should increase its import of natural gas and produce more electricity.

(d) Access to cooking gas can reduce premature deaths in poor

households.

Ans: D

Passage-3

Scientific knowledge has its dangers, but so has every great thing. Over and beyond the dangers with which it threatens the present, it opens up as nothing

 else can, the vision of a possible happy world; a world without poverty, without war, with little illness. Science, whatever unpleasant consequences it may have by the way, is in its very nature a liberator.

 

51. Which one of the following is the most important implication of the passage?

(a) A happy world is a dream of science.

(b) Science only can build a happy world, but it is also the only major threat.

(c) A happy world is not possible without science.

(d) A happy world is not at all possible with or without science.

Ans: A

Passage-4

The Arctic's vast reserves of fossil fuel, fish and minerals are now accessible for a longer period in a year. But unlike Antarctica, which is protected from exploitation by the Antarctic Treaty framed during the Cold War and is not subject to territorial claims by any country, there is no legal regime protecting

 the Arctic from industrialization, especially at a time when the world craves for more and more resources. The distinct possibility of ice-free summer has prompted countries with Arctic coastline to scramble for great chunks of the melting ocean.

 

52. Which one of the following is the most important implication of the passage?

(a) India can have territorial claims in the Arctic territory and free access to its resources

(b) Melting of summer ice in the Arctic leads to changes in the geopolitics.

(c) The Arctic region will solve the world's future problem of resource crunch.

(d) The Arctic region has more resources than Antarctica.

Ans: B

Passage-5

Being a member of the WTO, India is bound by the agreements that have been signed and ratified by its members, including itself. According to Article 6 of the Agriculture Agreement, providing minimum support prices for agricultural products is considered distorting and is subject to limits. The subsidy arising from 'minimal supports' cannot exceed 10 per cent of the

 value of agricultural production for developing countries. PDS in India entails minimum support prices and public stockholding of food grains. It is possible that, in some years, the subsidy to producers will exceed 10 per cent of the value of agricultural production.

 

53. What is the crucial message conveyed by the above passage?

(a) India should revise its PDS.

(b) India should not be a member of WTO.

(c) For India, food security collides with trade.

(d) India provides food security to its poor.

Ans: C

Passage-6

India's educational system is modelled on the mass education system that developed in the 19th century in Europe and later spread around the world. The goal of the system is to condition children as 'good' citizens and productive workers. This suited the industrial age that needed the constant supply of a compliant workforce with a narrow set of capabilities. Our educational Institutes resemble factories with bells, uniforms and batch-

processing of learners, designed to get learners to conform. But, from an economic point of view, the environment today is very different. It is a complex, volatile and globally interconnected world.

 

54. With reference to the above passage, the following assumptions have been made:

1. India continues to be a developing country essentially due to its faulty education system.

2. Today's learners need to acquire new-age skill-sets.

3. A good number of Indians go to some developed countries for education because the educational systems there are a perfect reflection of the societies in which they function.

Which of the above assumptions is/are valid?

(a) 1 and 3 only

(b) 2 only

(c) 2 and 3 only

(d) 1, 2 and 3

Ans: B

Passage-7

The practice of dieting has become an epidemic; everyone is looking out for a way to attain that perfect body. We are all different with respect to our ethnicity, genetics, family history, gender, age, physical and mental and spiritual health status, lifestyles and preferences. Thereby we also differ in what foods we tolerate or are sensitive to. So we really cannot reduce so many

 complexities into one diet or diet book. This explains the failure of diets across the world in curbing obesity. Unless the reasons for weight gain are well understood and addressed and unless habits are changed permanently, no diet is likely to succeed.

Directions for the following 3 (three) Items:

Read the following two passages and answer the items that follow. Your answers to these items should be based on the passages only.

Passage-1

The quest for cheap and plentiful meat has resulted in factory farms where more and more animals are squeezed into smaller lots in cruel and shocking conditions. Such practices have resulted in many of the world's health pandemics such as the avian flu. Worldwide, livestock are increasingly raised in cruel, cramped conditions, where animals spend their short lives under

 artificial light, pumped full of antibiotics and growth hormones, until the day they are slaughtered. Meat production is water-intensive. 15000 litres of water is needed for every kilogram of meat compared with 3400 litres for rice, 3300 litres for eggs and 255 litres for a kilogram of potatoes.

 

78. What is the most rational and crucial message given by the passage?

(a) Mass production of meat through industrial farming is cheap and is suitable for providing protein nutrition to poor countries.

(b) Meat-producing industry violates the laws against cruelty to animals.

(c) Mass production of meat through industrial farming is undesirable and should be stopped immediately.

(d) Environmental cost of meat production is unsustainable when it is produced through industrial farming.

Ans: D

Passage-2

A male tiger was removed from Pench Tiger Reserve and was relocated in Panna National Park. Later, this tiger trekked toward his home 250 miles away. The trek of this solitary tiger highlights a crisis. Many wildlife reserves exist as islands of fragile habitat in a vast sea of humanity, yet tigers can range over a hundred miles, seeking prey, mates and territory. Nearly a third of India's tigers live outside tiger reserves, a situation that is dangerous for

 both human and animal. Prey and tigers can only disperse if there are recognized corridors of land between protected areas to allow unmolested passage.

 

79. Which of the following is the most rational and crucial message given by the passage?

(a) The conflict between man and wildlife cannot be resolved, no matter what efforts we make.

(b) Safe wildlife corridors between protected areas is an essential aspect of conservation efforts.

(c) India needs to declare more protected areas and set up more tiger reserves.

(d) India's National Parks and Tiger Reserves need to be professionally managed.

Ans: B

 

80. With reference to the above passage, the following assumptions have been made:

1. The strategy of conservation of wildlife by relocating them from one protected area to another is not often successful.

2. India does not have suitable legislation to save the tigers, and its conservation efforts have failed which formed the tigers to live outside protected areas.

Which of the above assumptions is/are valid?

(a) 1 only

(b) 2 only

(c) Both 1 and 2

(d) Neither 1 nor 2

Ans: A
