标题: [求助]LSAT-3-4-24 怪题
有碰到这种推论EXCEPT题，记得有个傻子原则，原文中没出现的内容，则原文推论题中出现，一定错。下面这道，出现了N多新冬冬（绿条），竟然全对。本题答案是D, 欧觉得A,B,E也没错。

The brains of identical twins are genetically identical. When only one of a pair of identical twins is a schizophrenic, certain areas of the affected twin’s brain are smaller than corresponding areas in the brain of the unaffected twin. No such differences are found when neither twin is schizophrenic. Therefore, this discovery provides definitive evidence that schizophrenia is caused by damage to the physical structure of the brain.

24. If the statements on which the conclusion above is based are all true, each of the following cold be true EXCEPT:

(A) People who lack a genetic susceptibility for the disease will not develop schizophrenia

(B) Medications can control most of the symptoms of schizophrenia inmost patients but will never be able to cure it.

(D) It will eventually be possible to determine whether or not some one will develop schizophrenia on the basis of genetic information alone

(E) Brain abnormalities associated with schizophrenia are the result of childhood viral infections that inhibit the development of brain cells.

cold be true EXCEPT。找个选项和原文矛盾。所以无关的都不是正确选项。原文的例子是基因相同（genetically identical），却一个有病，一个没病。D说可以根据基因判断某个人是否有病。所以矛盾。

COULD BE TRUE EXCEPT 可能是真的，除了那个绝对不是真的选项（答案）......

GMAT阅读里好像没有这样的问题。。。

没听说过你说的傻子原则，我觉得这个原则不适用于归纳题中的could be true，因为这种题涉及推理，既然是推理就必然含有原文没有的东西。

本题问的是could be true，就是以下哪个答案的发生是合理的，是可能发生的。lawyer说的没错啊，这等于就是在问，哪个答案是不可能发生的，也就是哪个答案和原文矛盾了。

同意。

could be ture EXCEPT 表示“不可能为真”

无关项都属于“可能为真”，必须找到题干所否定的情况。

究其原因，没看明白题干
