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.
这题为什么选C啊？？作者: aomeisoft7 时间: 2010-9-21 19:07
(B) Palitito's Renaissance buildings are not threatened by pollution other than engine exhaust. 这和building没有一点关系啊，无关选项
(C) Tour buses typically spend less than one-quarter of the time they are in Palitito transporting passengers from one site to another. 旅游车本应该只用1/4的时间，就能走完线路。而因为没有parking，车子3/4的时间停在路边，没有熄火（排放污染）。所以修新的parking，能减少这3/4的排污量
(D) More tourists come to Palitito by tour bus than by any other single means of transportation. 更多的游客坐旅游巴士> 会造成更多的污染作者: aomeisoft7 时间: 2010-9-21 19:08
