大家好 , 先聲明 , 我同意這一題,不大向最近的GMAT走勢 (老题到是見過幾次) ,考生可不必理會.

這道題,小時後在X加上課的時候,黃老師也曾經發來練習過. 當時老師的講解,讓我頭昏腦脹不已.

今天再度見到這道題 @@ 還是昏頭 . 無能為力ing.

看完題幹,畫個邏輯圖,有迅速想到 : 找他因

但是 ,還是飆錯了 , (我飆B @@) ?昏頭中 @@

懇請指點 謝謝大家 :D
===============================================
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.

正確答案 E

題目說生病跟hypothalamus有關
e說根本無關,直接否定,所以選她

b無關,沒講到得x病是什麼原因,無法否定
另外,跟z也沒關係的
