I am really confused by this question, partially because I'm not sure what the question stem is asking us to do, but then also, I don't get why the answer is E. I think the q-stem wants us to consider one of the answer choices as the conclusion put out by the health association. I just feel very lost by this question.
The critic seems to undermine B, but I guess its wrong because its not something the Health Association would say? A-D don't seem to be things that the critic would undermine. They seem irrelevant.
The only way I look at E is that since volunteers are able to suceed, something stronger than a volunteer (being told by a physician) would also have to succeed and the critic's response is still applicable?
