Hi,
I've read the explanations but I'm starting to think I got this question right by luck.
My instant preface for the answer without going to the answer choices was that
you cannot attain a precise understanding of ambiguity. Those two mutually exclusive. "Precise understanding" in the conclusion is what I tied into the premise "ambiguity." Why should have to tie in the "enjoyment" when the argument is about the attainment of a precise understanding.
I ruled out a different reason.
Writers rely on ambiguity when they want to resort to personal expression. That doesn't rule out the plausibility that writers use ambiguity when they want to express other stuff, i.e cultural issues, history, foreign affairs etc. In this case, they may use words ambiguously because it's a campaign speech, and the vaguer you are, the more of a wider audience you can reach. In this case, how do you justify that voters won't try to understand precisely what you're saying?
My reasoning for A made C more confusing.
I settled with it because my assumption is that ambiguity and precise understanding are mutually exclusive. C sort of describes that. Please help
