Questions 23- 24

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 could 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 in most patients but will never be able to cure it.

(c)The brains of schizophrenics share many of the characteristics found in those of people without the disorder.

(D) It will eventually be possible to determine whether or not someone 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.

大家来看看这道题。

这题我觉得思路挺怪的，也许是lsat和gmat的差别吧。

题目问can be true EXCEPT，那就是说must be false。

选项只有D must be false，因为“alone”绝对化了；其他的都超出原文范围无法判断。

原文信息：同性双胞胎的脑基因相同，生S病是脑的物理结构受损（不是基因，基因还相同）

所以答案为D（MUST BE FALSE）：根据基因信息确定是否得S病。（和原文同性双胞胎的例子相反）

这道题的解题思路是找出最不可能为真的选项，也就是与题干直接相反的选项，而不需考虑可真可不真的选项。我这样理解对吗？做这道题是非常迷惑，看着五个选项没一个是真，或可从题干推出，真不知如何下手。

我认为只有D对。

呵呵，同意lawyer_1的分析。
