The correct answers are "it shows that Janie finally understands her grandmother" and "it suggests that Janie is searching for more than materialism".
Explanation: Janie was encouraged by her grandmother to marry for wealth. She now understands it because her grandmother worked hard her entire life, and felt that a wealthy, idle lifestyle was a better option. Now that Janie had experienced wealth herself, she knows that it didn't make her happy. She prefers her simple working life with Tea Cake.
