    41. Question

    Read the passage carefully and answer the questions given below

    The secret of writing good English is not just memorizing the rules of grammar; actually, it lies in developing the habit of unambiguous thinking and precise expression. Mathew Arnold, an English poet and prose writer, commented, “Have something to say and say it as clearly as possible.” Many of the students in Pakistan have no particular style because they have nothing to say. If any unclear idea they have, they express it vaguely. Perspicuity or lucidity is the prime requisite of an impressive writing style. In order to attain lucidity, we should avoid dangling of ideas, vagueness of expression, redundancy of arguments, and use of bombastic words.

    Read the passage carefully and answer the questions given below

    I should say to the reawakened nations of Asia. Your independence will not be very difficult to preserve, especially in view of the division of the rest of the world into two hostile camps. But what will perhaps be more difficult will be refrain from copying the mistakes of the west .The west throughout the last five centuries has displayed extraordinary energy – energy which has taken many forms, some good, and some bad. It has explored the world from Pole to Pole. It has learnt the secrets of atoms and stars. It has discovered how to produce such an abundance of necessaries and comforts as previous ages would have thought unimaginable .But all this, which might have ministered to human happiness, has been vitiated by one fatal fault; the love of power over other human beings. Africans and Asians alike have been tortured in the oppressed by energetic ingenuity of western conquest. If the word is to be happy energy and ingenuity must no longer be expended in the exploitation of those who have less of these of qualities. Mankind must learn a degree of mutual respect which has never hitherto existed. Perhaps some at least of the nations of Asia will have learnt this lesson from their suffering at the hands of ingenious despots.
