Answer:
The correct answer is: She tries to convince Misfit that he is a good man.
Explanation:
At the beginning of the story, the grandmother doesn't like Misfit and she tries to avoid his as much she can and to protect her children from him. However, her attitude changes when he captivates her family. She takes the main role in the liberation of her family and tries to convince Misfit he is a good man and he should let them go.
This fact affects the theme of the text because the grandmother becomes the main voice of the story, by taking the dominant role in her household, while she tries to protect her family from Misfit.
