标题: lsat-3-4-23
(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.

23. Which one of the following is an assumption required by the argument?

(A) The brain of person suffering from schizophrenia is smaller than the brain of anyone not suffering from schizophrenia

(B) The relative smallness of certain parts of the brains of schizophrenics is not the result of schizophrenia or of medications used in its treatment.

(D) When a pair of identical twins both suffer from schizophrenia, their brains are the same size

(E) People who have an identical twin are no more likely to suffer from schizophrenia than those who do not.

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.

文章结论实际上是在说：这种病是先天的。那么23题，e是怎么作为假设前提的？没有看出其中的关系！

24题e中的viral infections什么意思?这能说明上面的这个结论？d我想是因为alone过于绝对所以错了

个人认为23的答案是B, 24的答案是A, 不知道对不对。

23答案是B

24E说明了因果关系，所以support了，答案是D

答案分别是B D

请大家分析一下23题B怎样作为假设的

23同意B

24選D, 因為題目說了跟基因無關, 因此推不出D...

哈哈, 剛好跟icyeye mm 同時回貼...

B是assumption... 題目說因為X所以Y, B說明並不是因為Y所以X, 排除他因...

以下是引用Pudding在2005-2-26 18:13:00的发言：

是不是写错了？应该是：不是因为X所以Y吧？对吗？

沒寫錯... 有點像OG裡的一個題目:

題目說夫妻不同的睡眠時間導致婚姻失和, 前提是, 並不是因為婚姻失和所以兩人才故意錯開睡眠時間...

我的意思是, 兩件事中如果是果就不會同時是因....
