标题: 老题再问．．．ＮＮ答ＧＷＤ－３０－２７

1. GWD-30-Q27

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.

还是不动

哪位解释下吧．．．．．

c的意思是说strenuous activities 本身可能会导致一定的医疗费用，这个费用要是超过了由于锻炼节省下来的医疗费用，personnel officer 节省医疗费用的初衷就泡汤了；因此C的假设是必要的。

而B的意思是说那些被要求参加锻炼的人招致的医疗费用将比没有被要求参加锻炼的人要少。

这个答案实在是很有迷惑性，我第一眼也会选他，仔细思考后，我觉得：

这个假设不是必要的，就算not B，题目中的arguement照样可以成立。解释如下：

倘若“那些被要求参加锻炼的人招致的医疗费用将比没有被要求参加锻炼的人要多”，只要被要求参加锻炼的人身体好了，自己的医疗费用减少了，也就达到personnel officer目的了。
