51. 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.

                             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.（B）

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

答案B，陈在解释E是叙述道：E选项把一个结论成立的必要条件当成了该结论成立的充分条件。但是在解释归纳题的做法的时候陈又单列出一种“必要条件”题型，请问这里陈的解释对吗？B又是如何推出的？
