supports the fact that the buses have a lot of idle time at the curb..

more than 3/4 are parking there doing there nothing

correct me if i am wrong..

i think choice E is a bit confusing.

Can any NN explain the way to rule out E pls?

i think that the word "some" is resposible for the erroness.only two bus can be describe as some bus 

where does" two" come from?

i think E is just repeating the fact stated in the question.

So does not actually help to strengthen.

C说，一样的路，现在只要花原先1/4的时间，那么排气时间减少，排气量减少，建筑损坏减少
