(A): Out of scope - The passage does not talk about the circumstances surrounding government funding of the FTP, and therefore it is impossible to know whether it would have continued if the plays had been more popular. Using common sense knowledge, I believe that the Great Depression would have probably dried up the finances involved in the funding.
(B): Out of scope and Detail Creep - The passage does not talk about the artists of the Harlem Renaissance, and there seems to have been a diverse set of views instead of polarized views of the social function of art.
(C): Correct Answer - Didn't select this on the first round, because the philosophical and aesthetic disagreements put me off. They seemed to be words that I hadn't seen in the passage, although they seem to refer to the fact that there were diverse views and interests of the African community that led to cultural debates and diverse preferences for different types of dramas.
(D): Out of scope - The passage does not talk about African American theater artists working today.
(E): Detail Creep - There were diverse preferences for dramas, meaning that there were some who liked urban realistic dramas and some who liked folk dramas. The passage does not mention which one was more popular.
