Question

some people may doubt memoir not because they mistrust human memory but because they mistrust the authors morality. critics may suspect an author of exaggerating or even fabricating events. however, there is no reason to be suspicious of memoir authors intentions. entirely truthful memoirs are frequently at the top of nonfiction bestseller lists. with enough literary talent, an honest author can create an enticing, engrossing tale that will sell well. writing a factual memoir that appeals to readers has the potential to be profitable for the author, and there is no incentive for a memoir writer to knowingly alter or embellish the truth. a well - written memoir is compelling enough as it is.
the fifth paragraph is meant to support the authors main claim that memoir is best categorized under the umbrella of literary nonfiction. whats wrong with the authors argument in the fifth paragraph?
instead of providing evidence against a counterargument, the author attacks those who disagree with the main claim.
the author has created a straw man; it is untrue that anyone doubts the truth of successful memoirs.
it is contradictory to state that compelling memoir is profitable and also that there is no reason to embellish a memoir.
there is no evidence that memoirs are popular among nonfiction readers.

Explanation:

The author claims that a truthful memoir can be profitable and there's no incentive to alter the truth. But if a memoir is profitable (which might depend on being more engaging), there could be an incentive to embellish (even if the author says there isn't). This is a contradiction.

Answer:

It is contradictory to state that compelling memoir is profitable and also that there is no reason to embellish a memoir.
