Read the passage and answer the following question.
Days passed. The crocodile's wife was feeling more and more eager to eat the monkey's heart. So, she thought of a plan to get the monkey there. One day the crocodile's wife pretended to be very ill. She began to shed tears as if she were in great pain. The crocodile was sad to see his wife ill. He sat by her and said, 'What shall I do to help you?'
'I am very ill,' said the wife. I asked the doctor and he said that I would get well only if I ate a monkey's heart.
'A monkey's heart?' asked the crocodile.
'Yes,' said the wife, 'a monkey's heart. You must get your friend's heart if you want me to get well.'
'How can I do that?' the crocodile said, 'He is my only friend. I cannot think of doing him any harm.'
'Then you can go and live with your friend,' said the crocodile's wife, 'You don't love your wife. You love only your friend. You want to see your wife dead. Then you will be free to be with your friend always.'
The crocodile was very unhappy. He did not want to harm his friend. At the same time he could not allow his wife to die.
'How can I kill my only friend?' the crocodile asked again, and started shedding tears himself.
'Why can't you kill a monkey?' said his wife, 'Crocodiles have to kill monkeys.'
The crocodile shed more tears; he could not decide what to do.
'You don't love me,' said the crocodile's wife, 'A wife cannot live without her husband's love. I have decided to end my life. When you come back today from visiting your friend, you will find me dead.'
The crocodile began to think. As a husband he had to protect his wife. It was his duty. He decided to save the life of his wife. He went to see the monkey. The monkey was wondering why the crocodile was late that day and when he saw the crocodile he asked, 'Why, my friend, why are you so late? Did you meet with an accident on the way?'
'No accident,' said the crocodile, 'My wife and I had a quarrel. She said that I was not your friend. You have done so much for us, yet I have not invited you home. She has asked me to take you home today. She wants to meet you.'
'How sweet of her to ask me home,' said the monkey, 'I would also like to meet her. But how can I go there? You live in water and I shall be drowned if I try to get to your home.'
'We live on the river bank,' said the crocodile, 'I can easily take you there. You can ride on my back while I swim.'
The monkey thought it was a good idea. He felt happy that he had such good friend.
The monkey and the crocodile set out for the home of the crocodile. The monkey sat on the crocodile's back and the crocodile started swimming up the river. When they reached the middle of the river, the crocodile began to dive. The monkey was frightened. 'Hey,' he cried, 'What are you doing? I shall be drowned if you go down any further.'
