多谢楼上指点,OG11的解释如下:

Argument Construction

Situation    Finding that people with low immune-system activity score lower on mental health tests than people with normal or high levels of immune activity, a researcher concludes that the immune system protects mental as well as physical health.

Reasoning
                  What assumption does the researcher make? The researcher asserts that immune-system activity can inhibit mental illness as it does physical illness
While it is possible that mental i11ness might itself depress immune-system activity, the researcher assumes that this is not the caseIf mental illness caused a decline in immune-system activity, then lower levels of immune-system activity would be expected as a resultand the higher levels would merely indicate the absence of illness rather than any effect on illness.

A  The researcher does not distinguish between high and normal levels of immune-system activity, so this assumption is not needed

B  The researcher is investigating only mental illnessnot physical diseaseso this assumption is not needed

C  Immune-system activity could protect mental health without offering total prevention of mental illnessthis assumption is not needed

D  CorrectThis statement properly identifies does not decrease immune system activity the researcher's underlying assumption that mental illness

E  Since different treatments are not discussedany assumption about them is unnecessary

其实我的问题跟这个帖子的lz一样,也是觉得A、C取非后也是对原结论的削弱,因此迷惑,但是现在看OG11的解释,我的理解是A、C看起来还是跟原文无关阿!

不知道这样理解对否。最近是不是考试的人少或者是大家都太强了,好像没有多少人讨论这些老帖子。

我想借这个题问一下,什么情况下需要取非啊?是不是取非就一定能筛选出答案?可是从楼上的几位讨论来看,好像不一定啊。刚学逻辑,请nn指教啊,谢谢!!!

是不是可以这样理解

比如说 immune-system 高时 mental health 好可能 是I-S导致M-H,也可能是M-H导致I-S..

但是题中只从I-S高且M-S好就推出免疫能力决定精神健康程度

这样就忽略了M-H导致I-S的一面

所以答案是D
