Question

claim: it is ethical for food companies to sell unlabeled genetically modified food because customers can become confused if there are too many labels. reason: gmo labels reinforce stigmas about genetically modified foods. which piece of evidence most clearly supports this reason?
○ a recent study shows that most consumers negatively perceive a gmo label as a warning.
○ gmo foods can offer consumers nutritional benefits.
○ referring to gmo foods as \frankenstein foods\ stirs consumers’ emotions.
○ some gmo crops require fewer resources to produce, so they are good for the environment.

Explanation:

The reason given is that GMO labels reinforce stigmas about genetically modified foods. We need to find evidence that supports this. Option A states that most consumers negatively perceive a GMO label as a warning, which shows that labels create a negative stigma (since they are seen as a warning, implying something bad), thus supporting the reason. Option B talks about nutritional benefits, not stigmas. Option C is about the term "Frankenstein foods" stirring emotions, not about labels reinforcing stigmas. Option D is about environmental benefits, not related to stigmas from labels.

Answer:

A. A recent study shows that most consumers negatively perceive a GMO label as a warning.
