题目是这样的：
A research discovered that people who have low levels of immune system activity tend to score much lower on tests of mental health than do people with normal or high immune system activity. The researcher concluded from this experiment that the immune system protects against mental illness as well as against physical disease.
The research's conclusion depends on which of the following assumptions:
A. High immune system activity protects against mental illness better than normal immune system activity does.
B. Mental illness is similar to physical disease in its effects on body system.
C. People with high immune system activity cannot develop mental illness.
D. Mental illness does not cause people's immune system activity to decrease.
E. Psychological treatment of mental illness is not as effective as is medical treatment.
总感觉答案不够周延，请高手来点津，或者论坛里面有没这道题的讨论帖呢？多谢各位了！

答案是D吗？
题目的推导是：
免疫力较弱的人通常比免疫力强或免疫力正常的人在“mental health”测
试中得分低 －> 因此免疫系统不仅防御生理疾病，而且防御mental
disease
a 题目中没有比较免疫力强和免疫力正常的人在“mental health”上的得
分
b 同样，题目中没有提到相关信息（也显然违背常识）
c 同样，题目中并没有提到免疫力强的人就不会得mental illness
d 正确。如果我们假设这个选项的assumption错误，即mental illness会
导致人的免疫力下降，那么mental health得分低的人因为患有mental
illness机率高，所以导致免疫力较弱，因此我们就无法证明免疫系统是否
可以帮助人们防御mental disease
e 题目中没有相关信息

这个题目的内容来源就是“Report on Tourism”, 或者说题目讨论的内容是这个report的观点。思路如下：
题中条件（1）住在Spirng酒店的人数>住在Harris酒店人数
（2）住Harris最大酒店人数>住Sping RAH酒店人数
这两个条件同时正确看似矛盾，其实是报告没说清楚，认为Spring RAH概念等同于Spring酒店这个概念，即Spring只有 1家酒店RAH

谢谢及时回帖，答案是D，其他选项确实没什么争议，就是光有D感觉不太周延，这样一来“as well as against physical disease”这句话就可有可无了，既然加上了这句话应该不会当作常识部分默认吧，总觉得应该在假设中得到体现，比如加上免疫系统对mental illness和physical disease的致病机理是类似的这样的假设。大家怎么看呢？
