一道PREP的逻辑题 请各位帮忙看下 感激不尽

t is illegal to advertise prescription medications in Hedland except directly to physicians, either by mail or in medical journals.A proposed law would allow general advertising of prescription medications.Opponents object that the general population lacks the specialized knowledge to evaluate such advertisements and might ask their physicians for inappropriate medications.But since physicians have the final say as to whether to prescribe a medication for a patient, inappropriate prescriptions would not become more common.

Which of the following would it be most useful to establish in order to evaluate the argument?

(A) Whether advertising for prescription medications might alert patients to the existence of effective treatments for minor ailments that they had previously thought to be untreatable

(B) Whether some people might go to a physician for no reason other than to ask for a particular medication they have seen advertised

(C) Whether the proposed law requires prescription-medication advertisements directed to the general public to provide the same information as do advertisements directed to physicians

(D) Whether advertisements for prescription medications are currently an important source of information about newly available medications for physicians

(E) Whether physicians would give in to a patient's demand for a prescription medication chosen by the patient when the one originally prescribed by the physician fails to perform as desired

答案：E
第一次做选了C，后来看了看觉得该选D，不知道为什么选E 求解答 谢谢啊！！！

我觉得该题的落脚点是这样的（最后一句话）：因为医生有有最终权决定病人是否服用什么药，所以错误处方不会太常见。关键点在于：是否医生能成功决定病人买什么药呢，万一病人不听怎么办～所以E：是否医生能帮病人进行合理的处方选则，在以前处方没有效果的前提下。
C：医生与公众是否接收同样的广告与错误处方变少无关。
D：新药广告途经这个也无关。

这个argument归纳为一句话，就是“因为最后有医生把关药方，所以公开做药品广告没问题”。

所以要evaluate就是医生的把关是否有效,所以E是最佳选项。
