Dirt roads may evoke the bucolic simplicity of another century, but financially strained townships point out that dirt roads cost twice as much as maintaining paved roads.
(A) dirt roads cost twice as much as maintaining paved roads
(B) dirt roads cost twice as much to maintain as paved roads do
(C) maintaining dirt roads costs twice as much as paved roads do
(D) maintaining dirt roads costs twice as much as it does for paved roads
(E) to maintain dirt roads costs twice as much as for paved roads

弱弱得问一下， E为什么不能看作在as for 之中加了一个 those do（指代dirt roads）的省略内？NN指导一下下 ~

umm...加上了those do句意就不通了：
先将those do代回去：dirt roads costs twice as much as dirt roads do for paved roads.
dirt roads do what for paved roads?
原句的含义是dirt road要维护所花的费用是paved roads(要维护)所花的费用的两倍。
