20. (E)
Question Type: Assumption
This question asks us to find an assumption of the argument. The conclusion is that psychotherapists should never provide psychotherapy on talk shows. The evidence is that providing psychotherapy on talk shows is nearly always incompatible with providing high-quality psychological help. One problem with this argument is that while high-quality psychological help may not be provided, decent-quality psychological help may yet still be provided through talk shows. In order for the conclusion to be established, we need to assume that any attempt to provide psychological help that doesn’t provide high-quality psychological help should be avoided. This is perfectly stated in answer choice (E).
(A) misses the mark. The issue isn’t whether psychotherapists should attempt to entertain, but whether they should attempt to give advice that is less than high-quality advice.
(B) is irrelevant. Whether the context of the advice or the nature of the advice has a greater impact on quality is not important. This issue is whether psychotherapists should give advice if that advice is less than high-quality.
(C) this answer choice is simply too strong. If this were true, it would apply to all circumstances in which there were any chance that the psychological help would be of less than high quality. So, while this answer is sufficient to draw the conclusion, it is not necessary for the conclusion.
(D) is wrong. The reason why audiences tune in is irrelevant.
