164.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
这里选E

这里的E选项里没有加DO,是否会有歧义呢，因为不知道those是和vehicle比还是和pollutants比，就像I eat apple faster than you一样

我觉得因为those后面有burning gasoline or diesel fuel，就能说明这个是主语vehicle在比较了，因为pollutants不可能burning gasoline or diesel fuel
