The correct answer is A. A memoir relies on the narrator's memory, while a biography relies on various other sources and D. A memoir talks about a limited experience in a person's life, while a biography deals with a larger part
Explanation:
A memoir is a memory or set of memories written by an individual about specific events or moments that are part of the individual's life, a memoir does not aim at telling the whole story life of a person but just one or more important moments in the person's life. On the other hand, a biography is a description of the life of an individual including information about his/her family, education, profession, death, among others, which is usually written by someone else, instead of the individual itself.
This implies memoirs emerge from the memory, feeling and experience on the individual and focused on limited experiences because they do not tell all the information in a person life but such relevant events; on the other hand, biographies relly not only on the memory of the person but other sources such as documents or family testimonies and aims at describing the life of the individual as a whole and not only few events as in the case of memoirs.
