Answer:
Momma makes Marguerite C. take off her dress.
Momma does this because she wants to B. impress Mrs. Flowers.
One inference the reader can make about Momma's personality traits based on this action is that she is B. proud.
Step-by-step explanation:
In this passage, we see that Momma makes Marguerite take off her dress in order to show it off. She wants to show what a good job she has done with the dress and in this way, impress Mrs. Flowers. This embarrasses Marguerite, and Mrs. Flowers is aware of it, but Momma does not think about it. We can conclude that Momma is proud, as she wants Mrs. Flowers to appreciate the quality of her work.
