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.

新药如果没有专利保护，价格就比较低，但是同样的药在有专利保护的地区售价就比较高，因此为了新药的改进，应该废除各种专利保护。

文章推理：废除保护可以增加新药的改进

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.

没有专利保护，商家依然很有利润，但是和新药的改进无关

(B) Countries that do not currently grant patents on life-sustaining drugs are, for the most part, countries with large populations.

和人口无关

(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.

和其他的专利保护无关

(D) Pharmaceutical companies can afford the research that goes into the development of new drugs only if patents allow them to earn high profits.

正确，对新药的研究来自于专利保护创造的利润

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

和出口没有关系

我想问C为什么不对

如果其他程序被申请了专利 那么药价应该也无法下减啊

A major impediment to wide acceptance of electric vehicles even on the part of people who use their cars almost exclusively for commuting is the inability to use electric vehicles for occasional extended trips.In an attempt to make purchasing electric vehicles more attractive to commuters, one electric vehicle producer is planning to offer customers three days free rental of a conventional car for every 1,000 miles that they drive their electric vehicle.

对电动车使用的最重要的障碍就是不能长途旅行。电动车的买家为吸引顾客若，计划顾客每行驶1000英里电动车就免费租借普通车三天。

Which of the following, if true, most threatens the plan's prospects for success?

(A) Many electric vehicles that are used for commercial purposes are not needed for extended trips.

反对前提，前提已经说了需要长途旅行

(B) Because a majority of commuters drive at least 100 miles a week, the cost to the producer of making good the offer would add considerably to the already high price of electric vehicles.

正确，因为为了得到3天的免费租借，顾客必须每周至少跑100英里，无形中又增添了很多花费，所以不值得。这句话从卖家的角度，说明这个项目成本高。

(C) The relatively long time it takes to recharge the battery of an electric vehicle can easily be fitted into the regular patterns of car use characteristic of commuters.

和电池无关，说电池好更说明应该用电动车

(D) Although electric vehicles are essentially emission-free in actual use, generating the electricity necessary for charging an electric vehicle's battery can burden the environment.

说电动车的污染情况，和商家的计划无关

(E) Some family vehicles are used primarily not for commuting but for making short local trips, such as to do errands.

短途更说明商家的计划无用，而且有反对前提的嫌疑

反对前提

e 为什么不对 如果人们都用作短途 那根本没人去故意增加100公里的旅行 那个计划就没用了

For the first question, it has more to do with improving future access to new life-sustaining drugs than to lower the price of the drugs.  Therefore C is irrelevant.

For the second question, E doesn't hurt the proposed plan.  A free lunch or trip is still free.
