41. Which of the following inferences can be made from the passage? [2012-11]

1. Rainfed crops should not be cultivated in irrigated areas.

2. Farming under water-deficient areas should not be a part of development strategy.

Select the correct answer using the codes given below:

Today's developing economics use much less energy per capita than developed countries such as the United States did at similar incomes, showing the potential for lower-carbon growth. Adaptation and mitigation need to be integrated into a climate-smart development strategy that increases resilience, reduces the threat of further global warming, and improves development outcomes. Adaptation and mitigation measures can advance development, and prosperity can raise incomes and foster better institutions.

A healthier population living in better-built houses and with access to bank loans and social security is better equipped to deal with a changing climate and its consequences. Advancing robust, resilient development policies that promote adaptation is needed today because changes in the climate, already begun, will increase even in the short term.

The spread of economic prosperity has always been interwined with adaptation to changing ecological conditions. But as growth has altered the environment and as environmental change has accelerated, sustaining growth and adaptability demands greater capacity to understand our environment, generate new adaptive technologies and practices, and diffuse them widely.

As economic historians have explained, much of humankind's creative potential has been directed at adapting to the changing world. But adaptation cannot cope with all the impacts related to climate change, especially as larger changes unfold in the long term.

Countries cannot grow out of harm's way fast enough to match the changing climate. And some growth strategies, whether driven by the government or the market, can also add to vulnerability particularly if they overexploit natural resources. Under the Soviet development plan, irrigated cotton cultivation expanded in water-stressed Central Asia and led to the near disappearance of the Aral Sea, threatening the livelihoods of fishermen, herders and farmers.

And clearing mangroves the natural coastal buffers against storm surges to make way for intensive farming or housing development increases the physical vulnerability of coastal settlements, whether in Guinea or in Louisiana.

Correct Answer: (d) Neither 1 nor 2
Solution:Neither statement 1 nor 2 can be inferred from the given passage.

42. Consider the following assumptions: [2012-11]

1. Sustainable economic growth demands the use of creative potential of man.

2. Intensive agriculture can lead to ecological backlash.

3. Spread of economic prosperity can adversely affect the ecology and environment.

With reference to the passage, which of the above assumptions is/are valid?

Correct Answer: (b) Adaptation and mitigation should be integrated with development strategies.
Solution:The central theme of the passage is clear that adaptation and mitigation should be integrated with development strategies. The author is not against development but a sustainable development what he is talking about.

44. With reference to the passage, which of the following statements is correct? [2012-11]

Invasions of exotic species into new geographic areas sometimes occur naturally and without human agency. However, human actions have increased this trickle to a flood. Human-caused introductions may occur either accidentally as a consequence of human transport, or intentionally but illegally to serve some private purpose or legitimately to procure some hoped-for public benefit by bringing a pest under control, producing new agricultural products or providing novel recreational opportunities.

Many introduced species are assimilated into communities without much obvious effect. However, some have been responsible for dramatic changes to native species and natural communities. For example, the accidental introduction of the brown tree snake Boiga irregulars into Guam, an island in the Pacific, has through nest predation reduced 10 endemic forest bird species to the point of extinction.

One of the major reasons for the world's great biodiversity is the occurrence of centers of endemism so that similar habitats in different parts of the world are occupied by different groups of species that happen to have evolved there. If every species naturally had access to everywhere on the globe, we might expect a relatively small number of successful species to become dominant in each biome.

The extent to which this homogenization can happen naturally is restricted by the limited powers of dispersal of most species in the face of the physical barriers that exist to dispersal. By virtue of the transport opportunities offered by humans, these barriers have been breached by an ever-increasing number of exotic species. The effects of introductions have been to convert a hugely diverse range of local community compositions into something much more homogeneous. It would be wrong, however, to conclude that introducing species to a region will inevitably cause a decline in species richness there.

For example, there are numerous species of plants, invertebrates and vertebrates found in continental Europe but absent from the British Isles (many because they have so far failed to recolonize after the last glaciations). Their introduction would be likely to augment British biodiversity. The significant detrimental effect noted above arises where aggressive species provide a novel challenge to endemic biotas ill-equipped to deal with them.

Correct Answer: (d) None of the statements (a), (b) and (c) is correct in this context.
Solution:Option (a) is incorrect because the passage states that introduction of exotic species into geographical areas may increase biodiversity as well.

Option (b) is incorrect because it cannot say that introduction of exotic species by man into new areas have always and greatly altered the ecosystems.

Option (c) is incorrect because homogenization of local community population can also occur nationally.

45. Why does man introduce exotic species into new geographical areas? [2012-11]

1. To breed exotic species with local varieties.

2. To increase agricultural productivity.

3. For beautification and landscaping.

Correct Answer: (d) 1, 2 and 3
Solution:The first paragraph provides that human introduce exotic species to breed exotic species with local varieties (producing new agricultural products), to increase agricultural productivity (bringing pest under control) and for beautification and landscaping (recreational opportunities).

46. How is homogenization prevented under natural conditions? [2012-11]

Invasions of exotic species into new geographic areas sometimes occur naturally and without human agency. However, human actions have increased this trickle to a flood. Human-caused introductions may occur either accidentally as a consequence of human transport, or intentionally but illegally to serve some private purpose or legitimately to procure some hoped-for public benefit by bringing a pest under control, producing new agricultural products or providing novel recreational opportunities.

Their introduction would be likely to augment British biodiversity. The significant detrimental effect noted above arises where aggressive species provide a novel challenge to endemic biotas ill-equipped to deal with them.

Correct Answer: (d) All the statements (a), (b) and (c) given above are correct in this context.
Solution:One of the major reasons for the world's great biodiversity is the occurrence of centers of endemism so that similar habitats in different parts of the world are occupied by different groups of species that happen to have evolved there. Due to evolution of groups of species specific to local habitats, homogenization is prevented under natural conditions. Further, the extent to which this homogenization can happen naturally is restricted by the limited powers of dispersal of most species in the face of the physical barriers (ocean and mountain range) that exist to dispersal.

Homogenization is prevented under natural conditions also due to strong adaptation of groups of species to local physical and climatic conditions.

47. How have the human beings influenced the biodiversity? [2012-11]

1. By smuggling live organisms.

2. By building highways.

3. By making ecosystems sensitive so that new species are not allowed.

4. By ensuring that new species do not have major impact on local species.

The significant detrimental effect noted above arises where aggressive species provide a novel challenge to endemic biotas ill-equipped to deal with them.

Correct Answer: (a) 1 and 2
Solution:(a) This obviously the correct answer, because it is the most practical one. It is humanly possible to smuggle live organisms and to build highways.

(b) It is not easy nor practical to make ecosystems sensitive. So this option is ruled out.

(c) This option is also ruled out for the above said reason.

(d) It is very difficult and quite unnecessary to ensure new species do not have an impact on local species. So this option is also ruled out.

48. What can be the impact of invasion of exotic species on an ecosystem? [2012-11]

1. Erosion of endemic species.

2. Change in the species composition of the community of the ecosystem.

Correct Answer: (c) Both 1 and 2
Solution:Both the statements (1) and (2) are correct.

49. According to the passage, why is a serious tension perceived between democracy and development by the detractors of democracy? [2012-11]

Most champions of democracy have been rather reticent in suggesting that democracy would itself promote development and enhancement of social welfare-they have tended to see them as good but distinctly separate and largely independent goals. The detractors of democracy, on the other hand, seemed to have been quite willing to express their diagnosis of what they see as serious tensions between democracy and development.

The theorists of the practical split "Make up your mind: do you want democracy, or instead, do you want development?" often came, at least to start with, from East Asian countries, and their voice grew in influence as several of these countries were immensely successful- through the 1970s and 1980s and even later in promoting economic growth without pursuing democracy.

To deal with these issues we have to pay particular attention to both the content of what can be called development and to the interpretation of democracy (in particular to the respective roles of voting and of public reasoning). The assessment of development cannot be divorced from the lives that people can lead and the real freedom that they enjoy.

Development can scarcely be seen merely in terms of enhancement of inanimate objects of convenience, such as a rise in the GNP (or in personal incomes), or industrialization important as they may be as means to the real ends. Their value must depend on what they do to the lives and freedom of the people involved, which must be central to the idea of development.

If development is understood in a broader way, with a focus on human lives, then it becomes immediately clear that the relation between development and democracy has to be seen partly in terms of their constitutive connection, rather than only through their external links.

Even though the question has often been asked whether political freedom is "conducive to development", we must not miss the crucial recognition that political liberties and democratic rights are among the "constituent components" of development. Their relevance for development does not have to be established indirectly through their contribution to be growth of GNP.

Correct Answer: (b) Economic growth can be promoted successfully without pursuing a democratic system of governance.
Solution:The first paragraph in the passage conveys the message that the detractors of democracy are quite vocal about that fact that a number of non-democratic governments particularly in East Asia have successfully achieved economic development.

Options (a), (c) and (d) are automatically ruled out.

50. According to the passage, what should be the ultimate assessment/aim/view of development? [2012-11]

Most champions of democracy have been rather reticent in suggesting that democracy would itself promote development and enhancement of social welfare-they have tended to see them as good but distinctly separate and largely independent goals. The detractors of democracy, on the other hand, seemed to have been quite willing to express their diagnosis of what they see as serious tensions between democracy and development.

Their relevance for development does not have to be established indirectly through their contribution to be growth of GNP.

Correct Answer: (d) Extent of real freedom that citizens enjoy.
Solution:The second and last paragraphs illustrate the fact that freedom and liberty are essential components of development.
