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 sit.
这道选C ，我选的是E ，能不能解释下啊？作者: hazardous 时间: 2011-7-17 07:20
我是这么理解的。。C选项，Tour buses typically spend less than one-quarter of the time they are in Palitito transporting passengers from one site to another.意思是tour buses运送顾客的时间还不到全部在palitito时间的四分之一，也就是说它停下来idling等游客的时间是占四分之三，说明时间很长，应该治理，因此support了。E选项说Some of the tour buses that are unable to find parking drive around Palitito while their passengers are visiting a sit.文章中说了正常的开车的话，排放废气是没有idling多的，(and idling produces as much exhaust as driving)。。所以要说mostly support 的话，C肯定是咯。。我的拙见哈。俺5月考。。做逻辑脑袋也很混乱。。杯具作者: djblues 时间: 2011-7-22 06:18
idle 就是车打到P档，不关发动机，所以和开着车一样。
parking就是车的发动机关了，没有尾气排放了。
