标题: FeiFei-100

Zelda: Dr. L, a research psychologist, has convincingly demonstrated that his theory about the determinants of rat behavior generates consistently accurate predictions about how rats will perform in a maze. On the basis of this evidence, Dr. L. has claimed that his theory is irrefutablely correct.

Anson: Then Dr.L is not a responsible psychologist, Dr.L's evidence does not conclusively prove that his theory is correct. Responsible psychologists always accept the possibility that new evidence will show that their theories are incorrect.

Which one of the following can be properly inferred from Anson's argument?

A. Dr. L's evidence that his theory generates consistently accurate predictions about how rats will perform in a maze is inaccurate.

B. Psychologists who can derive consistently accurate predictions about how rats will perform in a maze from their theories cannot responsibly conclude that those theories cannot be disputed.

C. No matter how responsible psychologists are, they can never develop correct theoretical explainations.

D. Responsible psychologists do not make predictions about how rats will perform in a maze.

E. Psychologists who accept the possibility that new evidence will show that their theories are incorrect are responsible psychologists.

请问 E 为何不对呢？Thanks.

E 为ANSON最后一句话的逆命题，故不一定正确

多谢 lawyer, 还是不明白。在何种情况下 E 不正确? 举个例子吧。

再谢。

原文 Responsible psychologists always accept the possibility：Responsible——〉accept the possibility

E为Psychologists who accept the possibility are responsible ：accept the possibility ——〉responsible。

所以两者为逆命题，元命题正确，逆命题不一定正确。

麻烦请问了，那么B是怎么翻译的？

请大牛们指点下

我觉得应该选B,推理中premise是Dr.L's evidence does not conclusively prove that his theory is correct.Responsible psychologists always accept the possibility that new evidence will show that their theories are incorrect.结论是Then Dr.L is not a responsible psychologist. B选项就是上面条件部分的重述;

A, Anson的结论是基于DR.L从自己推理正确进而推出自己的结论无法推翻这个点来反驳的,至于推理部分没有说accurate与否

C can never过度极端,而且文中没有这两个比较的信息

D Responsible psychologists 只是不会说自己undisputable,至于能否make prediction无法得知

E 这个部分如lawyer所说,正向说明在文中,选项是反向说,但是反向成立与否不知
