关于885 sec11-16的新解释

Because natural gas is composed mostly of methane, a simple hydrocarbon, vehicles powered by natural gas emit less of certain pollutants than the burning of gasoline or diesel fuel.fficeffice" />

(A) less of certain pollutants than the burning of gasoline or diesel fuel

(B) fewer of certain pollutants than burning gasoline or diesel fuel do

(C) less of certain pollutants than gasoline or diesel fuel

(D) fewer of certain pollutants than does burning gasoline or diesel fuel（E）

(E) less of certain pollutants than those burning gasoline or diesel fuel

这道题的答案是E；看了CD上的3篇解释，集中在fewer of 和 less of，但是总感觉证据不充分。

我的想法是这道题考的是compare以及句意，compare的是名词，所以不需要有do或者does，根据这一点先排除B和D。

剩下A, C, E区别在于对burning gasoline的表述；C的错误在不符合原文的意思，原文比较的是pollutants, burning gasoline和diesel fuel，而不是gasoline；A不如E简洁；所以，E。

还有，我觉得E即使换成fewer of 也可以。

不知道我想的对不对，请大家指正。
