For years the beautiful Renaissancebuildings in Palitito have been damaged by exhaust from the many tour busesthat come to the city.  There has beenlittle parking space, so most buses have idled at the curb during each stop ontheir tour, and idling produces as much exhaust as driving.  The city has now provided parking thataccommodates a third of the tour buses, so damage to Palitito's buildings fromthe buses' exhaust will diminish significantly.
Which of the following, if true,most strongly supports the argument?

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




答案选C,LZ选的是B
为什么解释说bus花的时间少就可以方便政策的执行呢?和停车有什么关系呢?

意思是说通常旅游车花在转运乘客的时间要少于总时间的1/4,也就是说大部分时间他们都在路边停着空转,所以增加了停车场那就减少了他们停在路边空转,也就减少了废气排放
