Zelda: Dr. Ladlow, 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. Ladlow has claimed that his theory is irrefutably correct.

Anson: Then Dr. Ladlow is not responsible psychologist. Dr. Ladlow’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.

17.   Which one of the following can be properly inferred from Anson’s argument?

(A) Dr. Ladlow’s evidence that his theory generates consistently accurate predictions about how rates 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 disproved.

(C) No matter how responsible psychologists are, they can never develop correct theoretical explanations.

(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.

这题我用排除法，

A属无关选项；

C太绝对化，与Anson所说相反；

D的错更明显，说负责任的心理学家都不会做老鼠如何在玉米地活动的预测，显然很荒谬 ；

E典型的A－>B 不能推出 B－>A。

所以B对，可由文中的两个前提推出：1。research was not conclusive；2。Responsible psychologists always accept the possibility that new evidence will show that their theories are incorrect.

请指教！

你的解答让我茅塞顿开，总算明白E为什么不对。

不过maze应该是迷宫的意思。
