44. (33799-!-item-!-188;#058&007092)

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.
(E) Countries that grant patents on life-sustaining drugs almost always ban their importation from countries that do not grant such patents.

答案是D...我不懂啊~~~~很着急啊!!

D削弱说研究费用从专利中获取的，没专利就不能生产药了（原文说取消专利来降低药价，这样人人都能买得起这个药）
