What is the dominant conflict and two sub-conflicts in To Kill a Mockingbird?I have no idea what the answer is.
I'm not sure if I understand your question correctly, but if you are seeking the main conflict(s) in the novel, there are actually two: They basically serve as the two prime plots in TKAM. The first part of the novel concerns the children's attempts to either get a look at Boo Radley in the flesh, or at least lure him outside or make some sort of contact with him. The conflict arises when the children finally recognize that their harrassment of Boo actually invades his privacy. The main conflict in the second half of the story deals with Atticus's defense of Tom Robinson and whether Tom is guilty of the crime of which he is accused--the rape of Mayella Ewell. Atticus takes the case even though he realizes that defending a Negro accused of raping a white woman will cause problems for him and his family. As for other "sub-conflicts," there are the attempts, particularly by Aunt Alexandra, to make Scout more ladylike and Scout's refusal to give up her tomboy ways; and there are the problems Scout has with her teachers, Miss Caroline--whose modern teaching techniques don't mesh with Scout's already advanced skills--and Miss Gates, whose hypocrisy concerning Jews and Negroes are evident to even the immature Scout.
