For years the beautiful Renaissance buildings in Palitito have been damaged by exhaust from the many tour buses that come to the city.  There has been little parking space, so most buses have idled at the curb during each stop on their tour, and idling produces as much exhaust as driving.  The city has now provided parking that accommodates a third of the tour buses, so damage to Palitito's buildings from the buses' exhaust will diminish significantly.

Which of the following, if true, most strongly supports the argument?

(A) The exhaust from Palitito's few automobiles is not a significant threat to Palitito's buildings.
(B) Palitito's Renaissance buildings are not threatened by pollution other than engine exhaust.
(C) Tour buses typically spend less than one-quarter of the time they are in Palitito transporting passengers from one site to another.
(D) More tourists come to Palitito by tour bus than by any other single means of transportation.
(E) Some of the tour buses that are unable to find parking drive around Palitito while their passengers are visiting a site.

问题分析：A 说车的exhaust是否会对building产生威胁（这句话倒底是产生威胁还是不产生读起来有点乱，无所谓，找有关的就可以，方向不重要），原文没提，因为这个选项说的是automobiles而原文说的是bus，这两者之间有可能有关系，有可能没关系，不存在必然交集杀。B 说说building只会首engine exhaust威胁，这个engine和原文的bus有什么关系，不确定，杀。C 说bus只花了不到三分之一的时间把乘客从一个地运到另外一个地，就是说还有很多时间在这个地方呆着，是原文成立的前提，留着。D 说乘坐bus和乘坐其他交通方式的旅客哪个多，没说，杀。E 说bus找不到停车场，很扯的一个选项，干掉，杀。
