标题: 请教feifei 逻辑17题

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.

答案是c

请问B为什么不对,我觉得B就是排除了一个有可能造成性格差异的因素.

多谢!

关键是看所谓的horoscopes 是否一致，而不是看personality，作者假设前提是时间一致就是horoscopes 一致，这其中有地域差异，但是作者assumpt地域差异不影响horoscopes，从而立论。

X说：A=》B

Y说：在a条件下，同意X的观点，即A=》B；在b条件下，事实与X的观点相违背，即认为X没有把b条件的影响考虑在内。也就是说X认为b不会对结论造成影响。

个人觉得题目应该改成在Y的理解下，X的assumption或许更加恰当？
