Answer:
A.) to endear certain characters to us.
D.) to show characters’ educational levels.
Stowe's use of dialogue enriches the setting of the story in various ways. First of all, it makes the characters more realistic and endears certain characters to us. By representing their speech as it most likely sounded in real life, we feel like we get to know the characters better. This makes us care about them more deeply. Stowe also uses dialect in order to show the educational levels of the characters, as "standard" English is most likely to be used by characters who are literate and have received some education.
