14?. 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.
答案
. 怎么也想不通为什么另外一种medicineof head cold 的情况会对原文的sinus medicine进行weaken.

广告宣传说sineease costs the least per dose. and sineease is as effective per dose as the most effective of those other medications.所以才。。。
D 说有一种治疗head cold 的药物比sineease 价格还低，同时有和sineease相同的成份。
所以否定了假设前提sineease costs the least per dose。故消弱。

可是原文of the many over-the-counter medications marketed for the relief of sinus headache. sineease costs the least per dose. 的意思是在所有能缓解sinus的头痛的药里面, Sineease是最便宜的, 这样,即使其他的药比Sineease便宜,如果不属于"治sinus"的范畴的话, 没有办法否定原文的这句话啊. 难道说symptoms of head cold 是sinus的一种?

和sineease相同的成份，当然可以治疗sinus headache。
举个例子如果有药物Y,本来是治疗head cold ，但现在发现和sineease相同的成份，当然可以治疗sinus headache，只是以前不知道罢了。sineease是最便宜观点是广告说的，广告说得不对所以我们才举例反驳他。
symptoms of head cold 是sinus的是不是一种没关系。就像现在阿司匹林本来是治感冒的，现在发现还可以治胃病一样。

这一题的D我原来也有疑问，D说的药比SE还便宜，虽然D是WEAKEN但却违反了前提说的“SE cost
the least per dose”，是典型的错误。
但现在我看了上面的讨论我想，D中说的药和SE还是有区别的，可以认为是两种药，所以不是违反前提。题干说：在治这种头痛的所有药中，se是最好的选择。D说的药虽然不包括在题干中，但疗效相同，价格更便宜，所以weaken。
这题应该可以结案了。
