Why does Langston Hughes anwer his main queston with a list of questions and is he expressing political of societal values?

You might consider Unsettled Family Life as a theme shared with Alice Walker's Everyday Use. This theme is introduced very early in Hughes' life, when his father left the family for Mexico. From that point on, Langston's father plays a very small role in his life. Also at a young age, Langston is put in the care of his Grandmother Mary. She leads a settled life, but dies a few years after taking Langston under her wing. The Reeds, who are good caretakers, but are not family, then care for Langston. Carrie Hughes, Langston's mother, eventually returns to reclaim her of son and he joins his mother and his new stepfather in Cleveland. For the remainder of his life, his mother will perpetually separate and return to his stepfather, moving from city to city and state to state in the process. Langston's sense of home is therefore not a solitary location, but wherever his mother happens to be at the time.

Hughes' unsettled family life translates two ways. Firstly, Hughes never has a father figure he can idolize. As a result, he turns to speakers such as Booker T. Washington and writers such as W.E.B. DuBois for male guidance. Second, Langston's nomadic lifestyle as a youth continues into his adulthood, when he explores the world, in the process becoming a cultured individual. Although his unsettled family life was unfortunate, it prepared Hughes for his future as an influential poet and writer.
