Maybe the best way to understand why Answer Choice (C), in plain language, is incorrect is to think about how the stimulus made it clear that box office figures are of little to no help in understanding audience reactions, while (C) assumes that we can suddenly depend on box office figures to tell us anything about audience reactions.

This LSAT question ignores real-world context without explicitly accounting for such realities. In reality, coffee roasting decreases caffeine, with longer roasting reducing caffeine further. It's unreasonable that the correct answer implies considering drinking dark roast coffee while also advising caution, since it might contain more caffeine and upset the stomach more than lighter roasts, on the basis that irritation increases with caffeine consumption. The correct answer necessitates more information from the stimulus. Answer Choice (A) does not actually help to evaluate an argument unless you are unaware of real-world context. Furthermore, this is not the first question I have discovered to be inconsistent with reality and the rules. Let one do with such a thought what they might.
