Answer:
The biography uses a chronological structure; "Marian Anderson Sings" uses flashbacks to narrate the events.
Step-by-step explanation:
Marian Anderson was a black woman who became popular for singing at the Lincoln Memorial Hall. Such event made a huge turning point for African Americans to stand out for their rights.
The biography uses a chronological structure because it started from the beginning of Marian Anderson's life in an orderly fashion (from birth until she died).
"Marian Anderson Sings," on the other hand, uses flashbacks to narrate events. These flashbacks are vital in showing the important events that happened in a person's life. It also presents how the character made decisions regarding what happened during those times.
