题目
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?
选项
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.

人事专员:我们健康保险福利的高昂成本反映了员工所产生的高额医疗费用。总体而言,身体状况不佳的员工比身体健康的同事有更高的医生账单和更长的住院时间。因此,由于我们必须降低健康保险成本,我们应该向所有员工提供包括慢跑和举重的严格健身计划,并要求身体状况不佳的员工参加。
### 核心论点及正确答案方向
- **核心论点**
- **论据**:身体不佳的员工比健康员工医疗费用高,健康保险成本高。
- **论点**:通过提供健身计划并要求身体不佳员工参加能降低健康保险成本。
- **正确答案方向**
- 要使结论成立,需要假设该健身计划不会带来其他导致成本不降反升的因素,比如因健身计划本身引发的高额医疗费用等。正确答案应该是能在健身计划和降低保险成本之间建立合理联系或者排除可能阻碍降低成本的因素。
### 各选项分析
- **选项A**
- **内容**:一个健康的人会比一个身体状况不佳的人更少定期接受医生的常规体检。
- **分析**:该选项讨论的是两类人接受常规体检的频率,与健身计划能否降低健康保险成本这一核心话题无关,不能作为假设。
- **选项B**
- **内容**:被要求参加健身计划的员工所产生的医疗费用会低于不被要求参加的员工。
- **分析**:即使被要求参加健身计划的员工医疗费用低于不参加的员工,也不能确定整个计划就能降低公司总的健康保险成本,因为不知道健身计划本身是否会引发其他高额费用等,对论点的支持不充分,不能作为假设。
- **选项C**
- **内容**:该计划对身体状况不佳的员工所要求的剧烈活动本身不会产生比该计划所实现的任何削减(成本削减)都更大的医疗费用。
- **分析**:如果该健身计划本身不会产生比其能降低的成本更大的医疗费用,那么就排除了健身计划实施后可能导致成本不降反升的可能性,是使结论成立的必要假设。
- **选项D**
- **内容**:健身计划将服务更多身体状况不佳的员工而不是身体健康的员工。
- **分析**:健身计划服务哪类员工多少与能否降低健康保险成本并无直接关联,不能作为假设。
- **选项E**
- **内容**:参加健身计划的员工因病缺勤的时间会比不参加的员工少。
- **分析**:员工缺勤时间与健康保险成本的降低没有直接的逻辑联系,不能作为假设。
### 答案
正确答案是C。
