Correct Answer: B

Rationale: The main idea of the passage about High Fructose Corn Syrup is that it may be contributing to obesity in America. This is evident from the information provided in the extract, which discusses how HFCS has been linked to health issues, including obesity. Choice A is incorrect because the passage primarily focuses on the potential health risks associated with HFCS consumption, not just the examination by the American Medical Association. Choice C is irrelevant as it only talks about the manufacturing process of HFCS, which is not the central theme of the passage. Choice D is incorrect as it emphasizes the preference of rats for HFCS, which is a minor point compared to the potential impact on human health, particularly in relation to obesity.

Correct Answer: D

Correct Answer: B
