6.    Advertisement: For sinus pain, three out of four hospitals give their patients Novex. So when you want the most effective painkiller for sinus pain, Novex is the one to choose.

Which of the following, if true, most seriously undermines the advertisement’s argument?

(A) Some competing brands of painkillers are intended to reduce other kinds of pain in addition to sinus pain.

(B) Many hospitals that do not usually use Novex will do so for those patients who cannot tolerate the drug the hospitals usually use.

(C) Many drug manufacturers increase sales of their products to hospitals by selling these products to the hospitals at the lowest price the manufacturers can afford.

(D) Unlike some competing brands of painkillers, Novex is available from pharmacies without a doctor’s prescription.（D）

(E) In clinical trials Novex has been found more effective than competing brands of painkillers that have been on the market longer than Novex.

请教为什么D？C为什么不对。谢谢。

搜过后，看了所有解释，但没有一个是很CONVINCING的。

有些说不须处方药更方便，有些说是安全。

究竟不须医生处方的药，跟医院给此药（医院开药的，难道不是医生开的吗？那有啥方不方便的？），有啥必然联系？

当然，医生也可以开非处方药，但这许多者间有什么关系？脑子里一团糟啊！

请各位清楚解释一下。

同样疑惑，

hospitals give their patients意即处方药呀！

OTC非处方药不一定要在医院的药方拿吧？
