[求助]FeiFei-17 B为什么不是答案啊？

17. Psychologist: Some astrologers claim that our horoscopes completely determine our personalities, but this claim is false, I concede that identical twins---who are, of course, born at practically the same time---often do have similar personalities. However, birth records were examined to find two individuals who were born 40 years ago on the same day and at exactly the same time---one in a hospital in Toronto and one in a hospital in New York. Personalities of these two individuals are in fact different.

Which one of the following is an assumption on which the psychologist’s argument depends?

A.        Astrologers have not subjected their claims to rigorous experimentation.

B.        The personality differences between the two individuals cannot be explained by the cultural difference between Toronto and New York.

C.        The geographical difference between Toronto and New York did not result in the two individuals having different horoscopes.

D.       Complete birth records for the past 40 years were kept at both hospitals.

E.        Identical twins have identical genetic structures and usually have similar home environments.

答案：C

思路： Psychologist举例否原观点，举的反例必定是在原观点相同的前提情况下产生了与原观点不同的结论。原观点的前提情况是相同星座，结论是性格相同。反例的前提情况需要与原观点的一致，所以即是不管多伦多还是纽约生的星座是一样的。

A, 是无关选项，占星家们做没做实验对原文半点影响没有。

B, 是无关选项，心理学家们驳的是星象，跟文化没关系。

D, 是废话，重复了原文的背景。

E, 也是废话，重复了原文的背景。

我读起来B好像也是答案，属于排除他因啊。排除了因为文化造成的差异。
