Legislation has been proposed that would allow herbal treatment manufacturers to use in their advertisements customers’ claims that this treatment effectively combat certain diseases. Such advertisements would be permitted only for products that have long been in common use with no record of harm, even when used in high doses. The proposal’s backers reason that this criterion should ensure that such advertisement do no harm even if they lead people to take ineffective treatments, for if the products are safe when taken regularly in large doses, they should remain safe at smaller or equal doses.

Which of the following would, if true, most undermine the reasoning of the proposal’s backers?

A Most people who believe that herbal treatments are medicinally efficacious base their belief on rumors and folklore.
B The active ingredients in many orthodox medicines are extracted from herbs.
C If people are told that herbal treatments have health benefits, they may buy greater quantities of them.
D Most people who are taking a particular treatment for health problem generally will not at the same time try other treatments that may be more effective.
E If herbal treatments are widely believed to have benefits, then the prices of these products will increase.

欢迎大家给出答案和分析～～
谢谢大噶！！

感觉上，核心是such advertisement do not harm, 所以就是找harm。D，我的理解是，如果无效但无害的治疗耽误了有效的治疗，那实际上还是造成了harm

选D；同意楼上观点，虽然草药本身无害，但是正在用草药进行无效治疗的病人不会去尝试真正有效的治疗方式，因此实际上对病人有害。

其实带入场景就很好理解，实际生活中好多老人听信那些无用的保健品，虽然不会对身体造成直接损失，但是可能他们就盲目相信无用的保健品，而不去看医生做正规的治疗，其实还是耽误了病情造成了负面的健康影响。
