Historian: Those who claim that Shakespeare did not write the plays commonly attributed to him are motivated purely by snobbery. Shakespeare was the son of a glove maker, whereas every other person proposed as the true author of the plays was an aristocrat, and many of those who argue that one or another of these aristocrats wrote the plays are the aristocrats' descendants.
The historian talks of the background of the two set of people that is Shakespeare and other proposed authors and then concludes that the claim of other people is motivated because of this background What can be the flaw?
Clearly the historian fails to look for other reasons and bases his claim purely on one angleLet us see if any choice matches it.
The reasoning in the historian's argument is most vulnerable to criticism on the grounds that the argument
(A) presumes, without providing justification, that a claim cannot be true if those who advance it are motivated by snobbery
wrong. There is no connection made between truth and snobbery(B) takes for granted that anyone who is motivated purely by snobbery cannot also be motivated by legitimate historical evidence
The flaw is basing his claim on the background, but this choice takes that background along with other reasons (C) fails to consider adequately the possible motives of those who claim that Shakespeare did write the plays commonly attributed to him
again we are looking for the flaw of basing his claim on the background(D) fails to exclude the possibility that there might be legitimate evidence motivating those who reject Shakespeare's authorship
Correct. Follows the flaw we had thought of.(E) makes use of an assumption that one would accept only if one has already accepted the truth of the conclusion.
incorrect. There is no such assumption.D
