Conflicts resolved: Mama gets her house and a larger space for her growing family. Walter, by turning down Mr. Linder's check, becomes a man in his family's eyes--especially in his son's eyes, which is why he changes his mind. Beneatha seems to have a worthwhile direction to her life by her consideration of going to Africa to work. Ruth is proud of her husband and feels for once that her children will be in a better place with the move out of the apartment.
Conflicts unresolved: The audience never knows if Willie ever gets punished for stealing the Youngers' money, or if Walter finds a job that makes him feel worthwhile and significant. Similarly, since Beneatha does shift from one interest to another, the audience does not know for sure that she really sticks with her new goals. Finally, Hansberry leaves it wide open as to how the Youngers will fare in the unwelcoming white neighborhood.
