24. The interstitial nucleus, a sub-region of the brain’s hypothalamus, is typically smaller for male cats than for female cats. A neurobiologist performed autopsies on male cats who died from disease X, a disease affecting no more than .05 percent of male cats, and found that these male cats had interstitial nuclei that were as large as those generally found in female cats. Thus, the size of the interstitial nucleus determines whether or not male cats can contract disease X.

Which one of the following statements, if true, most seriously weakens the argument?

A.   No female cats have been known to contract disease X, which is a subtype of disease Y.
B.   Many male cats that contract disease X also contract disease Z, the cause of which is unknown.
C.   the interstitial nuclei of female cats who contact disease X are larger than those of female cats who do not contract disease X.
D.   Of 1,000 autopsies on male cats that did not contract disease X, 5 revealed interstitial nuclei larger than those of the average male cat.
E.   The hypothalamus is known not to be causally linked to disease Y, and disease X is a subtype of disease Y.

我在ADE中卡了会，率先排除A，然后卡DE。结果选了D，答案确实E。不知道为什么，分析中说D只是一个DATA，不能起到削弱的作用。后来我想了下，觉得DATA的范围一般都不大，即便是削弱也是小削弱，后来确实也是E比较好，不知我这么想是不是对呢？又或是分析中有其他意思？
