Which statement about facts in memoirs is not correct?

an author's descriptions of actual events are a way to include facts in a memoir.

An author's thoughts are used to indicate facts in a memoir.

Explanation:

A memoir is a written form of historical description of someone so the authors thought and personal opinion is not used to determine the fact.

So the statement that gives the sense of using the writer’s personal opinion as a fact in any memoir is incorrect.

The author can only illustrate, describe and incorporate dialogues based on what really happened and not include his own thoughts about it.
