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

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D



请大家分析为何D是Must Be False。我个人觉得D和其他选项一样文中并无完全提到。

没人解释吗？

D的意思是，鉴别是否是S病应该建立在基因上。而原文很明显在说明，S病并不缘于基因

原来这样，谢谢。
我想问一下，如果选项和文中无关那也是Must Be False，也就是Except。这个如何判断呢。是不是Except题，选项还是要和文中有关。
