Read the following passage carefully and answer the questions based on it. One of the great delusions of modern times is the prevailing belief that we are more civilized than our ancestors. At no other period of the history of mankind has the word 'civilization' been so often misused and misunderstood, it is not in the abundance of material alone that civilization lies. Neither does it consist of the advance of scientific knowladge, however amazing that may be. The inventions and discoveries of science have undoubtedly brought unheard of blessings and comforts to us. But they are  not civilization. What we have failed to see is that civilization is a special way of human behaviour, of thought and feeling. The essential quality of civilization lies in the spirit of man, in his attitude to himself, to his fellowmen and to life as a whole. Looking everywhere around us today, you will find that man has made no progress since the dawn of history, in his attitude towards his fellowmen. On all the highest pillars in cities of the world, you will find the figure of conqueror or a general soldier. We know far more about our killers and destroyers than about our saviours and saints. The warriors are the heroes of the world. What have scientific inventions given mankind?
