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.
答案是B，我选E

我觉得，文章没有提顾客觉得电动车贵了。顾客不买这种电动车只是因为不能做occasional extended trips，和价格应该无关的啊。。。。。没说价格高了顾客就不买呀~~~所以商家采取的政策就是让她们可以买车又进行短途旅行~~要削弱的话不是应该说买了这种车还是不能享受短途旅行么~~

那么E 说。因为家庭用车常做的是短途旅行，那么就达不到商家优惠政策要求的1000mile，从而削弱了成功可能性，因为这个优惠对于那些买车的人来说是优惠不到的。因而不能通过优惠获得想要的结果

E中的some就不对，一些个别情况应该不能够影响计划吧。

这也是我当初看了答案以后唯一觉得E不妥的地方。。。但B不太能接受么。。因为要附加自己的判断就是贵了大家不买这个条件进去。就觉得不好

electric vehicle producer 想通过优惠政策克服electric vehicle自身的缺陷来实现make purchasing electric vehicles more attractive to commuters的目的。B说 a majority of commuters drive at least 100 miles a week就是说10周就可以享受优惠，但是大量的租车费用最后还得羊毛出在羊身上---涨价，导致价格上不 attractive to commuters，事与愿违了
