D?

The stimulus assumes that the consumers' enjoyment of the beverage is a health benefit; I think the flaw in D may be true, but is irrelevant

Hi @hallerae, thanks for your post. You are given a specific test: compare health-related benefits with potential risks. You are then told that Yellow No. 5 *might* cause allergic reactions. This is not an "unproven claim" - it's just a statement regarding a possible side effect of Yellow No. 5. @Ashley-Tien's point is an important one. On Flawed Method of Reasoning questions, always focus on the flaw in the argument itself. To do so, focus on the conclusion, and assess whether the given premises support that conclusion. Here, the flaw is not reliance on an unproven claim - it's treating "enjoyment of a beverage" as a "health benefit." Hope this helps! Please let us know if you have any additional questions.
