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

答案选E. 就有一点不明白，为什么用less of修饰certian pollutants? 既然后者是可数名词？

因为是emit less of，less of certain pollutants做emit的宾语，而fewer 是形容词，没有名词词性。less可以做名词。
