3. 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 0.5 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, but, the hypothalamus is known not to be causally linked to disease Y, and disease X is a subtype of disease Y.

The two portions in boldface play which of the following roles?

(A) The first is a fact in support of the consideration that is one of two points of this argument; the second is the alternative point that weighs against the first.

(B) The first is an evidence that supports the consideration that the argument includes; the second is the fact that weighs against that consideration that could be drawn from the first.

(C) The first is a general principle that is against the conclusion; the second is that conclusion.

(D) The first is an evidence that supports the conclusion; the second is an exceptional example.

(E) The first is a fact in support of the conclusion that the argument depends on; the second is a fact that is against the first one.

I chose E. The key is B. What's the consideration here? Consideration is something you need to take into consideration when you make some decisions.

I think the first and the second both are the facts and the conclusion of this argument is "Thus, the size of the interstitial nucleus determines whether or not male cats can contract disease X" . And the conclusion can't be drawn without the first. So "the first is a fact in support of conclusion that the argument depends on". "the argument depends on" is kinda wield though.

E错在第二画线没法反对第一画线（the first one，即使知第一结论也无法否定），第二depends on（必要条件）语气太强。B的the first指第一个consideration，其实就是第一个结论。第一个consideration很可能推出的是用判断X的方法去判断X一类的病，具体到原文就是Y病(Y和X是大类和小类的关系)，第二个划线就是为了反对用判断X的方法去判断X一类的病这个第一个consideration很可能推出的第二个consideration。即B
