Read the passage given below and answer the questions that follow. Once, there was a renowned scholar who lived in a beautiful monastery with many of his pupils. He was known as a very effective teacher. Many of his students grew up to become great masters. One day, one of them was caught stealing from his fellow-students. They reported the incident to the teacher. But he took no action against the boy. A few days later the same boy was again caught stealing. And again the teacher did nothing to punish him. 'This made the other students angry. They requested the teacher to dismiss the thief. They even threatened to leave as a group if the boy was allowed to stay in the monastery'. The teacher called a meeting of the students. When they had assembled, he said to them: "You are good boys who know what is right and what is wrong. If you leave, you will have no trouble in joining some other school. But what about your brother who does not even know the difference between right and wrong? Who will teach him if I don't? No, I cannot ask him to go even if it means losing all of you. "Tears rolled down the cheeks of the boy who had stolen. He never stole and in later life became renowned for his integrity thereafter How did the other boys threaten the teacher for his inaction?
