单选题 In Britain (不列颠，英国) there once lived a king and he was very fond (喜欢的) of jokes (喜欢开玩笑). "I will give a bag full of gold (金子)to the person who can tell me the best (最好的) story (故事，新闻报道)." he said, "There is one rule (规则) , it must be a story which I cannot believe. If I can believe it, then I won't give away the bag of gold."
People came (来，出现) to the king from all parts of the country. They brought strange and wonderful (极好的，惊人的) stories. The king sat in his palace and listened to all the stories. He enjoyed them very much, but to each person he said, "I can believe that story. It could happen and it may be true. So I won' t give you the bag of gold."
At last a poor old man came to the palace. He was carrying a big jar (坛子). The old man went into the king's room and said, "Oh, King, your good father was once a poor man and my father was rich. They were very good friends. My father gave your father a large jar, like this one, and it was full of gold. Your father promised (答应) to give back the gold when he became rich. But he didn't give it back. Now I'm poor and you are rich. And I want the gold."
The king said, "I don't believe that story. The jar is very big. There isn't enough gold in all my country to fill that jar. My father didn't tell me anything about a large jar full of gold."
"All right." the old man said, "Never mind. If you don't believe the story, give me the bag of gold, please." The king remembered the rule and gave the man the bag of gold.

【正确答案】 C

【答案解析】A选项是错的，因为这故事本身就是虚构的，不存在还不还金子的问题。B、c根据第四段说的都有一定的道理。仔细琢磨，C选项更佳。因为现在虽然整个国家都没有这么多金子，但说不定他父亲在位时就有这么多金子呢。但有一点可以肯定，不管当时国家是否有这么多金子，这么大的事情，他父亲肯定会告诉他的。所以选C的理由更充分。
