The factor of Maya Angelou's memoir that makes it so vivid and full of vibrant life is: A. Setting. The reason is because, setting in a story is the background and description to give you a sense of where the story takes place. Rather than putting dull, boring words in a story, it is better to help the reader to feel as if he or she was actually there, through the use of descriptive words. There you go! Money in the sack, just for you, and lots of it! Alright, hope that helps you. ;)
