Which statement about facts and opinions in memoirs is true? a) facts and opinions in memoirs are synonymous. b) many of the facts in memoirs would be considered opinions in other types of nonfiction. c) there is no such thing as a fact in a memoir: everything is opinion. d) most of the opinions in memoirs would be considered facts anywhere else.

The correct answer should be
B) Many of the facts in memoirs would be considered opinions in other types of nonfiction

That is because memoirs are written based on memory so they recount things and events only from the perspective of the person who is writing, which is why they are often opinions. Writing something like WW 2 began would be a real fact anywhere, but any type of analysis of the event would be an opinion.
