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 passage 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 the 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.

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.

ANSWER :

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.

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.

ANSWER :

A. With more options for food come more risks.

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.

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.

ANSWER :

B. Science and faith can be mutually complementary if their proper domains are understood.

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.
