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.
(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。
(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.
