Answer: Falling Action
Explanation:
I believe that Mama, who gets hurt, and the results may be the falling action, because of the injury Mama sustained occurred after the Climax of the story.
"Even though I knew I hadn’t done anything wrong, it still bothered me that I’d been the cause of such trouble in our house."
When Maya says: "...I hadn’t done anything wrong" signifies that something wrong would most likely happen in the climax or rising action, and the word "hadn't" is a past tense that backs up our claim.
It cannot happen in the resolution because the resolution is the period in the story that has something to do with the end. We, the readers, know that this is not the ending of the story. Furthermore, this event falls in the falling action plot diagram category.
