Questions 100-101
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 a 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.

. 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 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 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

总觉得B怪怪的...原文只说了Dr. Ladlow这个 Psychologist不负责任，怎么变成了众多Psychologists都不负责任了？

100. Anson说Dr. Ladlow不是有责任感的心理学家，因为有责任感的心理学家会承认新的研究成果可能会证明他们的理论不正确。

他的思路是：非B(因为Anson不承认新的研究成果可能会证明他的理论不正确)-->非A(所以Dr. Ladlow不是有责任感的心理学家)

通过这个思路我们可以知道A-->B，即责任感的心理学家-->会承认新的研究成果可能会证明他的理论不正确。

而E的说法是B-->A，即承认新的研究成果可能会证明他的理论不正确-->就是责任感的心理学家，所以E错。

B的说法有点绕，意思是A和非B不可以同时存在，即心理学家不能“既有责任感”又“不承认他们的理论可能不正确”。
