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.

每开1000英里电车就要送3天的租用传统车的费用。

Which of the following, if true, most threatens the plan's prospects for success?

C   B

(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.

   由于人们每周至少开100英里，所以对于电车生产商来说负担不起这样的促销花费。

(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.

相对长的充电时间，人们是适应的。

(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.

这一题的C该怎么理解呢？答案是B。意思是不是电车价格已经很高了，再加成本价格就会更高呢？
