听力原文: There was once a man in South America who had a parrot, a pet bird that could imitate speech. The parrot was unique. There was no bird like him in the whole world. He could learn to say any word except one. He could not say the name of his native town, Ketunnel. The man did everything be could to teach the parrot to say Ketunnel, but he never succeeded. At first he was very gentle with the bird. But gradually, he lost his temper. "You stupid bird. Why can't you learn to say that one word? Say Ketunnel or I will kill you. "but the parrot would not say it. Many times the man screamed, "Say Ketunnel or I will kill you. "but the bird would never repeat the name. Finally, the man gave up. He picked up the parrot and threw him into the chicken house. "You are even more stupid than chickens." In the chicken house, there were four old chickens, waiting to be killed for Sunday's dinner. The next morning, when he went out to the chicken house, the man opened the door. He was shocked by what he saw. He could not believe his eyes and ears.. On the floor lay three dead chickens. The parrot was screaming at the fourth, "Say Ketunnel, or I'll kill you."
Why did the man lose his temper?

Because the bird screamed all day long.
C. Because the bird uttered the wrong word.
D. Because the bird failed to say the name of the town.
