关于头痛药的一道题

lisiberry

Advertisement: Of the many over-the-counter medications marketed for the relief of sinus headache. SineEase costs the least per dose. And SineEase is as effective per dose as the most effective of those other medications. So for relief from sinus headaches, SineEase is the best buy.

Which of the following, if true, most seriously weakens the argument above?

(A) Most of the over-the-counter medications marketed for the relief of sinus headache are equally effective per dose in providing such relief.
(B) Many of the over-the-counter medications marketed for the relief of sinus headache contain the same active ingredient as SineEase.
(C) People who suffer from frequent sinus headaches are strongly advised to consult a doctor before taking any over-the-counter medication.
(D) An over-the-counter medication that is marketed for the relief of symptoms of head cold is identical in composition to SineEase but costs less per dose.
(E) The per dose price for any given over-the-counter medication marketed for the relief of sinus headache is higher for smaller packages than it is for larger packages.

OA：D
有点疑惑，真的是D这么简单的答案？
原题说SineEase最便宜，D说还有另一种更便宜。
确实是削弱了，可是，感觉太简单了。考点在哪里呢？

C选项好有迷惑性，好吧可以引申为prescription medication 里有更好的for relief of sinus headache。这样的话比D选项就好了。可惜选项并没有明确指出这一点
D选项本来不是很认同，但是identical一词说明两个药品成分完全一样。cost per dose还低，那这个选项就是最相关的。
所以还是D选项是最佳选项。

嗯，我最开始也选的C。
果真选D的原因就是另一种药价格低。
感觉正确选项简单过度，迷惑选项又有点迷惑过头。

谢谢啦。

是的。太简单直白了，还有个难的混在里面，已经被gmat折磨的心力交瘁的一不小心病急乱投医就错选了C。我也犹豫过，D选项里的药物是用来治疗另一种的，即使成分一样，就可以成为减轻头痛的best buy了吗？？哎很有迷惑性啊。然而C选项实在不争气。没有提prescription一下就由最佳变成无关了啊，落差好大。
