Questions: 196 – 200
Directions (Q Nos. 196-200) Read the following passage carefully and answer the
questions given below it.
In this work of incessant and feverish activity, men have little time to think, much less to consider ideals and objectives. Yet how are we to act, even in the present, unless we know which way we are going and what our objectives are? It is only in the peaceful atmosphere of a university that these basic problems can be adequately considered. It is only when the young men and women, who are in the university today and on whom the burden of life’s problems will fall tomorrow, learn to have clear objectives and standards of values that there is hope for the next generation. The past generation produced some great men but as a generation it led the world repeatedly to disaster. World Wars II nd are the price that has been paid for the lack of wisdom on man’s part in this generation. I think that there is always a close and intimate relationship between the end we aim at and the means adopted to attain it. Even, if the end is right, but the means are wrong, it will vitiate the end or divert us in a wrong direction. Means and ends are thus intimately and inextricably connected and cannot be separated. That indeed has been the lesson of old taught us by many great men in the past, but unfortunately it seldom remembered.

A. they consider these ideals meaningless
B. they do not want to burden themselves with such ideas
C. they have no inclination for such things

A. the absence of wisdom and sagacity

C. his ignoring the ideals and objectives of life
