Direction: Read the passage and answer the following questions.

Nehru's was a many sided personality. He enjoyed reading and writing books as much
as he enjoyed fighting political and social evils or residing tyranny. In him, the
scientist and the humanist were held in perfect balance. While he kept looking at
special problems from a scientific standpoint. He never forgot that we should nourish
the total man. As a scientist, he refused to believe in a benevolent power interested in
men's affairs. But, as a self proclaimed non-believer, he loved affirming his faith in
life and the beauty of nature. He adored children. Unlike Wordsworth, he did not see

Direction: Read the passage and answer the following questions.

Nationalism, of course, is a curious phenomenon which at a certain stage in a
country's history gives life, growth and unity but, at the same time, it has a tendency
to limit one, because one thinks of one's country as something different from the rest
of world. One's perspective changes and one is continuously thinking of one's own
struggles and virtues and failing to the exclusion of other thoughts. The result is that
the same nationalism which is the symbol of growth for a people becomes a symbol
of the cessation of that growth in mind. Nationalism, when it becomes successful
sometimes goes on spreading in an aggressive way and becomes a danger
internationally. Whatever line of thought you follow, you arrive at the conclusion that
some kind of balance must be found. Otherwise something that was good can turn
into evil. Culture, which is essentially good become not only static but aggressive and
something that breeds conflict and hatred when looked at from a wrong point of view.
How are you to find a balance, I don't know. Apart from the political and economic
problems of the age, perhaps, that is the greatest problem today because behind it
there is tremendous search for something which it cannot find. We turn to economic
theories because they have an undoubted importance. It is folly to talk of culture or
even of god when human beings starve and die. Before one can talk about anything
else one must provide the normal essentials of life to human beings. That is where
economies comes in. Human beings today are not in mood to tolerate this suffering
and starvation and inequality when they see that the burden is not equally shared.
Others profit while they only bear the burden.

Direction (Question 76 to 79): Read the passage and answer the following questions.

Many sociologists have argued that there is functional relationship between
education and economic system. They point to the fact that mass formal education
began in industrial society. They note that the expansion of the economies of
industrial societies is accompanied by a corresponding expansion of their educational
systems. They explain this correspondence in terms of the needs of industry for
skilled and trained manpower, needs which are met by the educational system. Thus,
the provision of mass elementary education in Britain in 1870 can be seen as a
response to the needs of industry for a literate and numerate workforce at a time when
industrial processes were becoming more complex and the demand for technical skills
was steadily growing.

(A) its expansion needs sound learning

(C) industrial society gave rise to vocational education
(D) industrial society changed the pattern of education

78. The observation of the Sociologists are based on a study of

(A) the statistical data available in a historical context
(B) economic system of the 19th century
(C) the correlation between industry and education in a historical context
(D) growth of industry during 19th century

79. The Sociologists referred to in the passage say that the relationship between industry
and elementary education was one

(A) based on mutual need
(B) based entirely on the need of the industry
(C) based entirely on economic need
(D) based on some inexplicable historical forces
