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?
