The GoT references hit different. I prefer them more than the Jedi ones.

If it helps anyone, I went into this question with my strategy for point-of-disagreement questions. I first summarized the professor's argument and then the critics. It is not explicitly stated but the music critic disagrees with the professor's conclusion that rap music is individualistic and non-traditional. From using this strategy, I knew that the method of reasoning had to do with disagreeing or "challenging" the conclusion.

I can see why E is tempting because the critic touches on both aspects mentioned in the conclusion, but the critic mainly attacks the conclusion by showing that there are certain things he forgot to consider when forming his conclusion.
