1. Why didn't Beneatha want to be a doctor anymore?
She used to think that fixing people's ailments was the best thing to do. Now she thinks that physical ailments aren't the problem of society. People's hearts aren't true. She gives up on the human race and calls them "puny, small, and selfish." She sees no human battle worth fighting.
2. How did Asagai define "idealists" and "realists"?
"[Life] is simply a long line -- as in geometry, you know, one that reaches into infinity. And because we cannot see the end -- we also cannot see how it changes. And it is very odd but those who see the changes are called "idealists" -- and those who cannot, or refuse to think, they are the "realists."
3. What does Asagai ask Beneatha to do?
He asks her to marry him and return to Africa with him to live.
4. What fault does Mama find with herself?
She says she aimed too high -- had too-high dreams.
5. What solution does Walter have?
He thinks accepting the money from Lindner will solve their problem.
6. Why didn't Walter take the money Lindner offered?
Walter is a good, decent man underneath. His conscience and moral upbringing wouldn't let him ruin his family's pride.
7. Did the Youngers stay or move?
They did move.
