Directions—(Q. 1–12) Read the following passage carefully and answer the questions given below it. Certain words have been printed in bold to help you locate them while answering some of the questions.

Keshava, the washerman had a donkey. They worked together all day, and Keshava would pour out his heart to the doneky. One day, Keshava was walking home with the donkey when he felt tired. He tied the donkey to a tree and sat down to rest for a while, near a school. A window was open, and through it, a teacher could be heard scolding the students. ‘Here I am, trying to turn you donkeys into human beings, but you just won’t study !’ As soon as Keshava heard these words, his ears pricked up. A man who could actually turn donkeys into humans ! This was the answer to his prayers. Impatiently, he waited for school to be over that day. when everyone had gone home, and only the teacher remained behind to check some papers, Keshava entered the classroom.

‘How can I help you ?’ asked the teacher. Keshava scratched his head and said, ‘I heard what you said to the children. This donkey is my companion. If you made it human, we could have such good times together.’ The teacher decided to trick Keshava. He pretended to think for a while and then said, ‘Give me six months and it will cost you a thousand rupees.’ The washerman agreed and rushed home to get the money. He then left the donkey in the teacher’s care.

After the six months were up, Keshava went to the teacher. The teacher had been using the donkey for his own work. Not wanting to give it up, he said, ‘Oh, your donkey became so clever that it ran away. He is the headman of the next village.’ When Keshava reached the next village he found the village elders sitting under a tree, discussing serious problems. How surprised they were when Keshava marched up to the headman, grabbed his arm and said, ‘How dare you ? You think you are so clever that you ran away ? Come home at once !’

The headman understood someone had played a trick on Keshava. ‘I am not your donkey !’ he said. ‘Go find the sage in the forest.’ Keshava found the sage sitting under a tree with his eyes closed, deep in meditation. He crept up and grabbed the sage’s beard. ‘Come back home now !’ he shouted. The startled sage somehow calmed Keshava. When he heard what had happened, he had a good laugh. Then he told the washerman kindly, ‘The teacher made a fool of you. Your donkey must be still with him. Go and take it back from him. Try to make some real friends, who will talk with you and share your troubles. A donkey will never be able to do that !’ Keshava returned home later that day with his donkey, sadder and wiser.
