标题: GWD 9-8　请帮忙看一下，之前没讨论过THX!

答案选C，实在把我绕晕了。另外请教assumption答案中主句有not，一定是答案吗

Q8:

Personnel officer: The exorbitant cost of our health-insurance benefits reflects the high dollar amount of medical expenses incurred by our employees. Employees who are out of shape, as a group, have higher doctor bills and longer hospital stays than do their colleagues who are fit. Therefore, since we must reduce our health-insurance costs, we should offer a rigorous fitness program of jogging and weight lifting to all employees, and require employees who are out of shape to participate.

The conclusion reached by the personnel officer depends on which of the following assumptions?

A person who is fit would receive a routine physical checkup by a doctor less regularly than would a person who is out of shape.
The medical expenses incurred by employees who are required to participate in the fitness program would be less than those incurred by employees who are not required to participate.
The strenuous activities required of out-of-shape employees by the program would not by themselves generate medical expenses greater than any reduction achieved by the program.
The fitness program would serve more employees who are out of shape than it would employees who are fit.
The employees who participate in the fitness program would be away from work because of illness less than would the employees who do not participate.

结论：需要向员工提供健身项目。。。以降低健康保险费用

C: 这些激烈的活动不会造成更高的医疗费用（抵消了健康活动所降低的费用）

提高费用呼应了结论中的降低。你可以做一个测试，对C项做一个肯定回答，看看结果是否导致题目中结论的削弱。“这些激烈活动提高了费用”；不正好反驳了结论吗？

有not就一定是答案？这我没听说过。有人如此总结过这类题目吗？

谢谢bandito，assumption题还是老老实实地用not+weaken的方法作，以前passion的小班曾说过优先看主句有否定词的选项，但发现很多题这种方法都不奏效
