The new perfume Aurora smells worse to Joan than any comparably priced perfume, and none of her friend likes the smell of Aurora as much as the smell of other perfumes. However, she and her friends must have a defect in their sense of smell, since Professor Jameson prefers the smell of Aurora to that of any other perfume and she is one of the world’s foremost experts on the physiology of smell.
The reasoning is flawed because it
(A) calls into question the
truthfulness of the opponent rather than addressing the point issue - WRONG. Irrelevant.
(B) ignore the well-known fact that someone can
prefer one thing to another without liking either very much - WRONG. Covers only experts aspect and does not relate it to Joan and friends aspect.
(C) fails to establish that there is
widespread agreement among the experts in the field - WRONG. Irrelevant.
(D) makes an
illegitimate appeal to the authority of an expert - CORRECT. Takes a biased view and concludes.
(E)
misrepresents the position against which it is directed - WRONG. "misrepresentation" is wrong.
There is a diversion in what Joan and friends feel and how it is rejected based on experts feeling. This where it falters; the choice that brings this into light is the right answer.
Answer D.
