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 serously undermines the advertisement's argument? (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. 在论坛里搜索了一下,只看到关于B和C的讨论,而C和D的讨论没有结果 在最开始做的时候,我毫不犹豫选择了C,认为C是一个非常典型的他因替代解释。OG给出的答案也是C. 但是,后来在听Feifei的网络课堂时,Feifei一直强调,这道题需要一个常识,就是关于在美国处方药和非处方药的区别。正因为D是非处方药,所以,患者去了医院都会要求医生开Novex,为了买药的方便。而C中低价促销的策略是针对所有药的,不仅不能说明削弱结论,反而加强了结论,即Novex是最有效的。 另外,综合Feifei总结的规律之一:当两个事物进行比较时,如果其他方面都是相同的,那么只能加强结论,举例夏利和富康的区别。 所以,我现在困惑了,这道题的答案到底是C还是D?
