Answer: Maggie is upset that Wangero has asked for her quilts
Step-by-step explanation:
We can see from the passage that Maggie is feeling upset or angry because the second that Wangero asked for her quilts, she starts to do something in the kitchen. She slammed the kitchen door so the others can see and feel her emotions of anger.
She is trying to show that to her mom and by that, she thinks that her mom would save her quilts because of her anger. That is why she is showing that she is upset.
