OG-178请教

178.In countries in whichnew lifr-sustaing drugs cannot be patented,such drugs are sald at widely afforable prices;those same drugs,where patented shield patent-holding manufactures from competitors.These facts show that future access to new life-sustaining drugs can be improved if the practice og granting patents on newly developed life-sustaining drugs were to be aolished 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 te most part,countries with large population.

(C)In some countries specific  processes for the manufacture of pharmaceutical drugs can be patented even in cases in which th edrugs themselves cannot be patented.

(D)Pharceutical 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.

这个题目我根本就没看懂，希望哪个学长能帮我解释一下，这道题目最后那句话我觉得比杨老师的难句教程还要难。谢谢了

本题可看作“措施达目的”题型：措施：取消专利-----------------目的：是药物更用以获得，

                                                                          假设或前提：取消专利不会影响药物的生产和R&D

题目问的是削弱，答案D，断桥法

如果药没有专利，那么卖的就便宜；如果有专利的保护，就会卖得贵，因为竞争者少了。因此，如果所有地方的这些药都没有专利的保护的话，人们就受益。

大致的翻译。看懂就可以了。

做D选项的时候，突然产生了奇怪的想法：原来没有patent的国家，他们的药厂是怎么研发新药的？所以觉得D违反了原条件，然后选了C。

现在想想，也可以说药是同个公司生产的，只不过销售地区可以patent的就卖得贵，不行的就卖得便宜。用patent的premium来研发。

不过这些也是自己想的，好像没什么理论根据？思维好像有点问题……该怎么往正确的方向想问题？

另外OG对C的解释让人很费解。。。Choice C is incorrect since the possibility of patenting manufacturing processes introduces some limitation to the benefits of abolishing patents on the drugs, but does not mean that there would be no benefits. 

换句话说，要同一个药对比，不能对比两个专利的药和一个专利的药。
