标题: FeiFei-103疑问

Questions 102-103

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

(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

小的实在是不解答案为什么是 D，想请问大家如何来解此题？谢谢！！

原文的identical twins 的脑genetically identical，但一个schizophrenic，另一个没有。所以单靠genetic information 不能确定一个人是否schizophrenic，D却说相反，故必错（could be true EXCEPT）。
