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.
题目分析：A说一个健康的人和一个不健康的人哪种人接受体检更频繁，原文没说过这个比较，杀。B说那些参加锻炼的人和那些不参加锻炼的人那个医疗费用高，也没说过这种比较，杀。C说健身的那些program生成的医疗费用不会高于program本身，这个选项就是说健身后没有别的花费产生，明显是把其他出口堵死的支持方法，留着。D说健身项目适用于哪种人更多一些，没提，杀。E说那些健身的和不健身的哪种人因病离开工作的更多，显然没说，杀。
