Hello. You forgot to report that this question was about "To Kill a Mockingbird". It is important that you always provide all the information necessary for your question to be answered, as you deserve.
Answer:
Scout overhears Atticus and Aunt Alexandra talking about whether Calpurnia needed to stay in the house.
Explanation:
Scout is a girl who although very young manages to understand very well the situations that happen around her. She lives with her brother, Jem; his father, Atticus; and a black maid named Calpurnia.
Calpurnia was primarily responsible for creating Scout (her mother died) and everyone in the family has a high regard for Calpurnia.
Meanwhile, Scout's family is visited by Aunt Alexandra, a very prejudiced woman who believes that Calpurnia should be fired and sent home, since she is black and, according to her thoughts, inferior and a bad influence.
One day Scout overhears his father and aunt Alexandra arguing in the living room. They are talking about whether it is necessary for Calpurnia to remain in the house, as Aunt Alexandra found it absurd that Calpurnia would take the children to a service in an African church, even with Atticus's permission.
The excerpt provides background information on a character as part of the exposition.
