问题 单项选择题

据对一批企业的调查显示,这些企业总经理的平均年龄是57岁,而在20年前,同样的这样企业的总经理的平均年龄大约是49岁。这说明,目前企业中总经理的年龄呈老龄化趋势。 以下哪一项,对题干的论证提出的质疑最为有力( )

A.题干中没有说明,20年前这些企业关于经理人选是否有年龄限制

B.题干中没有说明,这些总经理任职的平均年数

C.20年前这些企业的总经理的平均年龄,仅是个近似数

D.题干中的信息,仅仅基于有20年以上历史的企业

答案

参考答案:D

解析: 本题是一道削弱型逻辑题。题干的结论是目前所有企业中的总经理的年龄呈老龄化趋势,但是前面的“一批企业的调查”,仅仅是对于有20年以上历史的企业。结论以偏概全,D项是最有力的质疑。

When I was at University I studied very hard. But a lot of my friends did very little work. Some did just enough to pass exams. Others didn’t do quite enough. Fred Baines was one of them. He spent more time playing than working in the library.

Once at the end of the term, we had to take an important test in chemistry. The test had a hundred questions. Beside each question we had to write “True” or “False”. While I was studying in my room the night before the test, Fred was watching TV. Fred usually worried a lot the night before a test. But on that night he looked perfectly calm. Thenhe told me of his plan. “It’s very simple. There are a hundred questions and I have to get fifty correct to pass the test. I’ll just toss(掷)the coin to decide the answers. That way, I’m sure I’ll get half the questions right.”

The next day, Fred came happily into the exam room. As he sat tossing a coin for half an hour he marked down his answers. Then he left, half an hour before the rest of us.

The next day, he saw the chemistry professor in the corridor. “Oh, good,” he said to the teacher, “Have you got the result of the test?” The teacher reached into his pocket and took out a coin. He threw it into the air, caught it in his hand and looked at it.

“I’m terribly sorry, Fred,” he said, “You failed!”
