理解

我觉得 C 支持claim 是因为The city has now provided parking that accommodates a third of the tour buses,和Tour buses typically spend less than one-quarter of the time they are in Palitito transporting passengers from one site to another.这2句话的理解

前一句说政府只提供了三分之一的车parking 后一句说每辆车只用了四分之一的时间把旅游者从一个景点带到另外一个景点

也就是说提供的车位能满足所有的旅游车,那么就是对文章的支持
