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 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.
(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 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.
Key is D, 能帮我解释一下 b c e选项么?
只要是could be true就不能选,要选的是那些肯定与文中信息相反的东西.那么文中没说到的自然就could be true就不会是答案.
(e)文中说到了schizophrenia及所谓的成因,但Brain abnormalities没说到过,所以就可能由childhood viral infections引起.
