First of all I will provide the definition of a problem novel, also known as social novel; it is work of fiction in which a prevailing social problem, including gender, race, or class prejudice, is dramatized through its effect on the characters of a novel.
So, accortding to this explanation, To Kill a Mockingbird can be considered a problem novel because it narrates the story of Tom who is accused of rapping a girl and the judge who convicted him of the crime did not believe his innocence just because he is not a white man. In other words, since Tom is black, he is considered guilty of the repe. which is an example of rascisms; a severe issue endured by many in the United States.
Moreover, through the novel, the characters have to cope to different challenges and obstacles while they grow up,so, they change as the story goes on and ther view of the world changes as well.
