(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. (E) In clinical trials Novex has been found more effective than competing brands of painkillers that have been on the market longer than Novex.
原题里是医院的概念,而D却偷换了概念,变成了parmacies了。 题目给的原因是因为医院给病人开药大多都开N,所以N有效。 反驳它,为什么C不对呢?C的逻辑是医院,因为采购成本低,从药商那里买来很多的N,所以不是因为有效。 而D的逻辑是,在药房里可随意买到。在药房里可以随意买到,跟医生开药有什么关系呢? open to discussion
