FEIFEI 103

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.

 

103. 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 schizophrenics share many of the characteristics found in those of people without the disorder

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

 

 

答案是C哦，为什么D对呢？

D must be wrong because as said in the sentence "The brains of identical twins are genetically identical", so it is impossible to "determine whether or not someone will develop schizophrenia on the basis of genetic information alone"

啊。。难道我的答案有错。。我这个版本的FEIFEI103的答案是D哦～

既然是identical twins,那么他们的gene应该是完全相同的啦～题目中给出edidence来看，determine on the basis of genetic information alone怎么可能是对的啊。。

迷惑了～

答案是D的。
文章开头说到了The brains of identical twins are genetically identical，就是说twins的基因是一样的，但是他们其中有人得schizophrenic有人不得，所以很明显，单靠gene是不能确定是不是会得schizophrenic的。D项正好与原文相反，不可能是真的。
