Despite years of public health campaigns encouraging fruit and vegetable consumption, recent national surveys indicate that the average adult's intake of these foods has not increased significantly. Simultaneously, there has been a notable rise in the popularity and availability of highly processed 'health foods' and dietary supplements. Some nutritionists infer from this that the public is generally more receptive to quick-fix solutions for health than to fundamental dietary changes. This inference is most open to criticism on the grounds that it:
Correct: D
The inference is that the public is more receptive to 'quick-fix solutions' (processed health foods, supplements) than 'fundamental dietary changes' (fruits/vegetables). The flaw here is that the rise in one type of consumption doesn't necessarily mean it's *replacing* the other or that people are choosing one *over* the other due to receptiveness. It's possible people are trying to do *both*, or that these 'health foods' are consumed by a different demographic. Choice D directly challenges this by pointing out that the rise in 'health foods' might be complementary, not competitive, with fruit/vegetable intake attempts. If people are trying to do both, the 'receptiveness' inference is weakened. Choice E is a broader statement, but D provides a concrete scenario that undermines the specific causal link proposed in the inference. Choices A, B, C miss the core logical leap about 'receptiveness' and the interaction of these trends.
