The correct option is E A discussion of persistent racial unrest in American society
The correct answer would be option E. The conversation between Troy and Rose was about the introduction of racial integration in baseball. The characters emerge to the point agreeing on the futility of discrimination and that merit is what matters. The racial unrest in American society has been long going, and its effects have been felt in every spectrum of the citizens' lives. The sports talk is just a way to mask the ongoing struggle. The statements of the other options are incoherent with the tone of the text. This excerpt is not just about Troy's baseball career, or how the neighborhoods have evolved. Troy's son isn't mentioned in the entirety of the text. Therefore, options A,B,C and D are incorrect in this context.
