Source of qu? Wanted to strike out E as it introduced new information that initially appeared unrelated.

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.


I too believe it's E and the reason for this is highlighted in red.

I don't think it's D because D states that the whatever nuclei were larger than those of the average male cat and not of the same size as those of female cats. What if indeed the male cats had larger nuclei, but they weren't nearly as large as those of females?

E is out of scope, you need to assume something in E that is not in the argument

Re: The interstitial nucleus, a subregion of the brain's [#permalink] New post 25 Jul 2013, 22:11
This question is from the June 1999 LSAT (section 3, logical reasoning).

The credited response is E. I hated this question, and hated this answer choices. Narrowed my final selection down to D and E. Both answer choices seemed incredibly weak, leaving me to guess D.

However, after further reflection I realized that, if anything, D seemed to weaken the argument. If disease X affects no more than .05 percent of all male cats, and 1,000 autopsies are performed on male cats who did not contract the disease, finding only 5 of cats with larger interstitial nuclei would seem to support the idea that size affects the likelihood of contracting the disease (because the 995 cats with average sized nuclei did not contract it).

While, in hindsight, E seems slightly more compelling, the answer is so deceptively worded, lending to my frustration in connecting it to the the conclusion of the argument. The stimulus discusses the interstitial nucleus, noting that it is only a subregion of the hypothalamus. E states that the hypothalamus itself is known not to be linked to disease Y, of which X is a subtype. Confusing, but if the interstitial nucleus is a subregion of the hypothalamus I can see how the two could be considered one in the same (a similar argument could be made for the X/Y subtype classification).

An expectedly tricky question # 25.
