Final answer:
Maya Angelou employs sensory, concrete details in her biography to vividly portray Aunt Tee's character and engage readers.
Step-by-step explanation:
In the excerpt from Maya Angelou's biography "Living Well, Living Good," the narrative technique used to reveal the character of Aunt Tee and engage readers is C. sensory, concrete details.
Angelou's description of the setting through the use of vivid sensory language—"...jokes were told, fingers snapped, feet were patted, and there was a great deal of laughter..."—allows readers to visualize the scene and hear the sounds of laughter and rhythm.
This technique not only paints a clear portrait of Aunt Tee's environment but also helps to establish the mood of the narrative, making it more vivid and engaging. It is a way of showing rather than simply telling about Aunt Tee's character and the atmosphere she is surrounded by.
