【GMAT考满分逻辑CR题库】A group of scientists have studied schizophreni_真题_答案

题目内容

A group of scientists have studied schizophrenics in an isolated community in Costa Rica with the objective of learning about the causes of schizophrenia worldwide. A flaw in this strategy is that schizophrenia is characterized by impaired emotional responses, and the way emotional responses are learned may differ across cultures of the world. It might even be fair to say that, on what is now a largely interconnected planet, a schizophrenic in an isolated community is a schizophrenic of no practical interest.

Which of the following, if true, would most weaken the argument made above about the group's approach?

A
All schizophrenics have certain features in common which, if studied, would help scientists to learn about the causes of schizophrenia in general.
分析该选项
B
Living in an urban environment during childhood or as an adult doubles the risk of schizophrenia in an individual.
分析该选项
C
To understand schizophrenia, it is necessary to learn about not just impaired emotional responses, but also paranoid beliefs, hallucinations, and disorganized thinking.
分析该选项
D
The group of scientists will not draw conclusions about schizophrenics as a whole from their findings in the isolated community.
分析该选项
E
Of the schizophrenics present in the isolated community, more than half have travelled abroad in their adulthood.
