(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.

(C) The use of an ambiguous term

(D) The discrediting of facts

2nd question, I don't believe A can be the answer because it is not a personal attack. The first sentence: "Then Dr. ladlow is not responsible psychologist" is a conclusion drawn from a general principle given in the second half of Anson's argument

B was also a contender to me for question 1. I see how E can be negated now. Let:
A= Responsible psychologist
B= Accept the possibility that new evidence will show that their theories are incorrect
The stem says If A then B
E says if B then A. This is not necessarily true for B can be for other reasons than A
Nice question Aspire!
