can anyone explain this?
For years the beautiful Renaissance buildings in Palitito have been damaged by exhaust from 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 thier tour, and idling produces as much exhaust as driving. The city has now provided parking that accomodates a third of the tour buses, so damage to Palitito's buildings from teh buses' exhaust will diminish significantly.
Which of the follwing, if true, most strongly supports the arguement?
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) Most tourists come to Palitoto by tour bus than by any other single means of transportation
E) Some fo the tour buses that are unable to find parking drive around Palitito while their passengers are visting a site
