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?
Many electric vehicles that are used for commercial purposes are not needed for extended trips.
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.
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.
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.
Some family vehicles are used primarily not for commuting but for making short local trips, such as to do errands.
电动车的一大问题是不能保证上班族偶尔用车长途旅行。为了增加电动车对上班族吸引力，一家生产商计划开电动车每1000里就可免费租传统车3天。
计划题 目标是吸引上班族买电动车，题目削弱目标
(A) 很多商业用电动车不必长途旅行；计划是针对上班族，商用电动车跳出范围，排
(B) 因大量上班族每周开至少100里，计划成本会大大增加电动车价格；计划导致高价，减少吸引力，削弱目标，正确
(C) 电动车充电时间符合上班族习惯；增强，方向反，排
(D) 尽管电动车无排放，但产生充电需要的电仍会影响环境；对环境的影响，与目标无关，排
(E) 一些家用车主要不是为了上班，而是做短途旅行；some，无意义概率，且是针对的非上班族，无关，排。
