The interstitial nucleus, a subregion 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 who 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 who 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.

答案选E，我觉得选D

D只是重复了题目的意思，没办法削弱啊~~

E中，如果X是由Y引起的，而Y和脑子里的啥啥啥有又没什么关系的话，那么X也和脑子没什么关系

呵呵~~我是这么理解的，不知道对不对？

我做的时候觉得选C，后来才发现题目里的结论是说公猫的脑子的大小和得X病有关系，C都在说母猫。。。。

额。。。不好意思，我刚刚好像理解错了，题目里说公猫的interstitial nucleus一般来说比母猫的小，然后在解剖的患X病的公猫里发现这些猫的interstitial nucleus和母猫的一样大，公猫里一般有不到0.05%会得X这个病。D里面说，在解剖的1000只没有得X病的公猫中，有5只的interstitial nucleus比一般的公猫大，好像和题目没什么关系~

谢谢楼上牛牛的快速解答！

麻烦问一下是不是D选项中的interstitial nuclei larger than those of the average male cat.，改成as large as the size of the female cat ，就有削弱结论the size 决定得不得病了啊？！

我觉得好像不会，因为D里面说的1000只公猫都是没得病的~D选项应该和整个题没什么关系~我是这样理解的~呵呵~~

我觉得结论the size of the interstitial nucleus determines whether or not male cats can contract disease X.
的得出是由于证据当得病male的size和female的size，但是如果没得病的male cats中有些size如果和female一样的话，就削弱结论，因为size和female的一致的除了得病的，还有没得病的

噢~~~~听你这么说，我觉得挺有道理的~~这样应该是对的~

再看看有没有其他NN来答这个问题吧！呵呵~~~

恩。好的。谢谢！

这道题我遇到过对象是RAT的,呵呵
我当时选C
闷啊~
