Read the following passage carefully and answer the questions given below it.
Games, though essential, should not become the be-all and end-all of student life. Generally some students waste too much time on them, and fail in their examination. One must never devote more than an hour to sports, and after that, should not even think about them. Again, if a player plays a game rashly, there is every danger of his breaking a limb. If it is played without the spirit of sportsmanship, it can lead to bad blood and quarrels. In some of the colleges there is a tradition that if the visiting team is winning a match, the home team plays foul, picks a quarrel, and tries to injure the visitors. But in spite of all these minor defects, sports are very useful in keeping the students busy and in developing their personalities. India expects its citizens to have the qualities of true sportsmen. If we all acquire these qualities, there will be no narrow-mindedness, no corruption and no injustice. There will be independence in the real sense of the word.
