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. 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.

B. 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.

C. 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.

D. The fitness program would serve more employees who are out of shape than it would employees who are fit.

E. 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.

为嘛不能选B?? 为啥选C？？？

原文大意：

因为——身体不好的员工增加了公司的医疗支出

所以——公司组织身体不好的员工锻炼，以降低费用

关键点：

因为——医疗支出

所以——降低费用

比较：

医疗支出 〉降低费用

C选项，恰好是说：公司组织员工进行锻炼不会导致医疗支出大于公司所降低的费用。所以正确

B选项意思是：那些身体不好，需要参加锻炼的人的医疗费用比那些身体好不需要参加锻炼的人要少。与原文意思相反。所以错误。
