求问一道模考的CR题目

题目如下：
A major impediment to universal access to medication is the high cost of patented drugs, which are often specifically required by patients for survival. In an attempt to make such drugs more widely available to patients, one drug company is planning to offer patients a free one-month drug supply for every $1,000 they spend on patented drugs.

问削弱

A. Many patented drug are not designed to be used for more than 2 weeks.
B. The drug company offering free one-month supplies will increase their prices so that the effective cost per dose remains the same.
C.D.E. 均已排除

答案给的是B，我选的是A，后面细看，A好像说的和病人可以扩大用药可能性没什么关系；而B好歹影响了价格，所以有一定关联；但是我始终没有搞懂B 的 effective cost per dose是什么意思，等于说这个选项最后是靠相关性来选而不是内容意义来选择，希望有大神能够帮我解答一下

这个意思就是说商家通过涨价去cover他提供 free supply的成本。
就好像，超市里说买一送一，然后暗戳戳地把价格提高了两倍，就使得per cost是不变的。

看到LZ这道题，让我想到了下面这个，很像的，你可以看看：

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 1000 miles that they drive their electric vehicle.

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
B. because a majority of commuters drive at least 100miles a week, the cost to the producer of making good the offer would add considerably to the already high price of electric vehicles （选这个因为只有这个选项与方案有关）
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
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
E. some family vehicles are used primarily not for commuting but for making short local trips, such as to do errands.

啊，你这么说我有点理解了。这个模考题搞不好是根据这一道真题改编的也不一定。
