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.

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 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.
(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.

A不对，我认为A否定了文中说的信息，文中说过 临时扩展行程。你选择A就和文中冲突了。这里不正确。B的解释我理解的是，因为.....不管原因，它太高了电车的价格，所以会起到削弱的作用。别的选项就可以第一遍就排除了。我认为应该是这样子。

希望能回答你的疑问，我做prep07的时候发现很多 加强，削弱的题目，其实加强 削弱的程度非常的低。就一点点作用特别容易弄错。不知道你是否有这种感觉？
