Read the given passage and answer the questions that follow.


A fisherman, enfeebled with age, could no longer go out to sea, so he began fishing in the river. Every morning he would go down to the river and sit there fishing the whole day long. In the evening he would sell whatever he had caught, buy food for himself and go home. It was a hard life for an old man. One hot afternoon while he was bemoaning his fate, a large bird with silvery feathers alighted on a rock near him. It was Kaha, the heavenly bird. “You should not be doing such work at your age,” said the bird. ‘From now on I will bring you a big fish every evening. You can sell it and live in comfort’. True to her word, the bird began to drop a large fish at his doorstep every evening. As big fish were in great demand, the fisherman was soon rolling in money. He bought a cottage near the sea, with a garden around it and engaged a servant to cook for him.

One day, he heard the royal courtier make an announcement. ‘Whoever can give information about the Kaha bird and help catch it will be rewarded with half the kingdom !’ ‘Why does the king want the bird?’ he asked. ‘He has lost his sight and a wise man has advised him to bathe his eyes with the blood of Kaha.” Do you know where she can be found?’ he asked. ‘No…I mean …no, no…’ the fisherman could not give a coherent reply. The courtier, sensing that he knew something about the bird, took him to the palace. ‘If you have information about the bird, tell me. I will personally crown you king of half my domain’, said the king. The fisherman agreed. ‘But Kaha is strong. I will need help’. The king sent a dozen soldiers with him. That evening when Kaha came with the fish, the fisherman said, ‘Today I have laid out a feast for you. Please alight and come in so that I can thank you’. Kaha was reluctant but the fisherman pleaded so earnestly that she finally gave in, and alighted. The moment she was on the ground, the fisherman grabbed one of her legs and shouted to the soldiers for help. They rushed to his aid, but their combined effort could not keep Kaha down.

She rose into the air with the fisherman still clinging onto her leg and neither he nor Kaha were ever seen again.
