A.cost (making ? )can not be compared with maintenance. B.could be an option but s-D looks better. C.Paved roads doesn't do anything-maintenance is done(by some one else) on the paved roads. D.RIGHT because,maintaining is parellel to "ït does". E.to maintain is not appropriate with "cost" IMO -D please explain the right answer.

I try my best to look at comparsions as X as much as Y where the sentences X and Y are constructed the same way. Additionally now I try to figure out meaning as well of the original sentence. With this sentence we are trying to say "Something about Dirt roads costs twice as much as paved roads". Based on these two things this is what I would have done -> (A) dirt roads cost twice as much as maintaining paved roads Split 1: Cost of dirt roads != maintaining paved roads(B) dirt roads cost twice as much to maintain as paved roads do Split 1: "X costs twices as much as Y does" - Looks fine(C) maintaining dirt roads costs twice as much as paved roads do Split 1: "something to X costs as much as Y does" This construction looks awkward because you are doing something to X but then flipping the structure with Y. (D) maintaining dirt roads costs twice as much as it does for paved roads Split 1: Here you are saying something costs twice as much as cost for Y. The structure is flipped in this one as well so wrong.(E) to maintain dirt roads costs twice as much as for paved roads Split 1: Here the construction is flipped as well. Since To something X twice as much as For Y.Based on this analysis I would have picked B. Comparsions are very tricky but based on what I know, I try to always keep the construction the same on both sides of the comparison keyword (Like, Unlike, As, Than, idioms). I don't have my Manhattan's SC book on me but I remember a piece regarding how to use As Much As from the idioms list.

The structural analysis has given me a new way to look at SC questions. This strategy will take me far!

More than a parallelism question, this is really testing comparisons. (A) dirt roads cost twice as much as maintaining paved roads --Comparing dirt roads and maintaining paved roads? WRONG(B) dirt roads cost twice as much to maintain as paved roads do CORRECT(C) maintaining dirt roads costs twice as much as paved roads do Comparing maintaining dirt roads and paved roads? WRONG(D) maintaining dirt roads costs twice as much as it does for paved roads What does it refer to? you may say maintaining, of course! But how come maintaining does something?  WRONG(E) to maintain dirt roads costs twice as much as for paved roads Does this even make sense? To maintaing costs twice as much to maintain for something?

Good question, i like some of the comparisons my initial thought was also D the subject is dirt roads, the list is paved roads and dirt roads, the cost of each. Unfortunately after that i got stuck
