C选项看不太懂,求助!

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.

答案是C

Necessary assumption. Use negation.

If you negate C, you have:
The strenuous activities required of out-of-shape employees by the program WOULD by themselves generate medical expenses greater than any reduction achieved by the program.

If so, it beats the purpose of the employer to use fitness group as a means to reduce medical cost. Thus, when you negate C, the conclusion falls apart. C is the necessary assumption.

我觉得B选项更适合用于加强结论。但是假设题和加强题不一样,假设题是搭个桥使结论在条件下能够成立。你可以试试把两个选项都取非,C选项比B选项更大程度上削弱了原题。而且大多数情况下,假设题的答案都是否定句。。。
我不是大神。。。不知道你能不能明白==

B) is not necessary.  The whole paragraph builds on the hypothesis that employee with an active life style would incur less in medical bills.

B) compares employee who are "required" to participated in the fitness program against who are not, neither of which has been mentioned in the passage.

Necessary assumption is a must-be-true type of questions, which would not allow NEW evidence.

B) is new evidence.  Thus, B) could not be the correct answer.

In addition, even if B) is negated, the conclusion of the passage could still be correct. When you negate B), you have:
The medical expenses incurred by employees who are required to participate in the fitness program would be NO less than those incurred by employees who are not required to participate.  So what! This condition or constraint is meaningless to the conclusion since iff these out-of-shape employees improve their health and thus reduce their medical bills, the total insurance cost for the company can be reduced.  So the conclusion still holds.
