请问og-178
178. In countries in which new life-sustaining drugs cannot be patented, such drugs are sold at widely affordable prices; those same drugs, where patented, command premium prices because the patents shield patent-holding manufacturers from competitors. These facts show that future access to new life-sustaining drugs can be improved if the practice of granting patents on newly developed life-sustaining drugs were to be abolished everywhere.
Which of the following, if true, most seriously weakens the argument?
(A) In countries in which life-sustaining drugs cannot be patented, their manufacture is nevertheless a profitable enterprise.
(B) Countries that do not currently grant patents on life-sustaining drugs are, for the most part, countries with large populations.
(C) In some countries specific processes for the manufacture of pharmaceutical drugs can be patented even in cases in which the drugs themselves cannot be patented.
(D) Pharmaceutical companies can afford the research that goes into the development of new drugs only if patents allow them to earn high profits. D
(E) Countries that grant patents on life-sustaining drugs almost always ban their importation from countries that do not grant such patents.
If without patents pharmaceutical companies could not afford to develop new drugs, then abolishing patents would mean that people would have reduced access to new life-sustaining drugs, thereby weakening the argument presented. Therefore, choice D is the correct answer.
请问答案d是如何削弱的?本题是属于"要反对A是B的原因,就说B是A的原因"的模式,有是怎么一回事.
想了半天没想明白,很难开窍,谢谢nn帮忙解答 |
