OG11th-85

85. 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

B is Correct.

对于(D)  OG说: It has no referent; 为什么呢? 我记得见过几次这种表达啊  比如:"For those other clans, access to water was less limited than it was for the Anasazi."  这句是705页上第98题的解释里的一句话; OG自己都这么用啊

偶到是觉得 cost 这个动作不是paved roads发出的 而是 maintaining paved roads 发出的 我的疑问就是 it 能不能仅指代“maintaining”？有点怪哈   因为看我举的那句话：:"For those other clans, access to water was less limited than it was for the Anasazi."  这个IT明显指的就是access

QUOTE:

D中, it指代了maintaining dirt roads,是错的,至少在GMAT中,我看到it都是指代单数的名词.

OG说没有指代对象就是没有指代对象

如果IT指代了maintaining dirt roads，如果变成maintaining dirt road就正确了的话，那后面的 paved roads是什么？(maintaining dirt road) does for paved roads太错了，it does(costs)  for paved roads看起来好像IT要和前面保持平行，但cost 这个动作本来是paved roads发出的，现在成了it发出，it是什么又不知道.

不晓得我理解的对不对

就是说 it 是个代词，前面应该有个单数的名词让它指代，但是这里没有。所以错。
