Can you please brief on E more ?
Why it is inferior to B?
I have read the above discussion but I still have this doubt
Read the option as X costs twice as much as Y and then look for parallelism. If we had something like

... to maintain dirt roads costs twice as much as to maintain paved roads.

We'd have ended up with a super awkward (but parallel) construction. In its current form, option E reads

... to maintain dirt roads costs twice as much as for paved roads.

Just because something is parallel doesn't mean that it is correct. There could be any number of other things wrong with an option in which parallel construction is maintained.

By the way, my example was just to help show that the elements in option E are not parallel.

... to maintain dirt roads costs twice as much as for paved roads.[/quote]

The example that you are referring to in your question is not there in the 5 options.

Hi I just watched you GMAT webinar for SC and i must say they are just the best.
I still have a doubt in Option B . Do is a pronoun that refers to something that is plural and so in this context it is referring to The Cost of maintaining the Paved roads where cost is singular. Can you please explain.
Thanks in advance

There are multiple things we have to look at here:

1. Do is a verb (auxiliary, but that's not important), not a pronoun. In other words, do so does not refer to a noun. This usage of do is as a substitute for a verb or verb form that has already been mentioned:

(a) They do so every day.
(b) He does so every day.

Here I've assumed some activity, so you won't see a verb or verb form for the do, but take a look at why the do changes to does. The do changes to does because the subject changes from they to he. This is a case of making the subject and verb agree (and not pronoun agreement).

2. Cost can act as both a noun and a verb.

(c) The cost of X has fallen in the last year. <--- here cost is a singular noun and agrees with the singular verb has fallen
(d) The costs of X have fallen in the last year. <--- here costs is a plural noun and agrees with the plural verb have fallen

(e) This product costs nothing. <--- here costs is a singular verb and agrees with the singular noun (subject) this product
(f) These products cost nothing. <--- here cost is a plural verb and agrees with the plural noun (subject) these products

When we say the cost, cost is a (singular) noun, and do cannot refer to it. But in option B:

... dirt roads cost twice as much to maintain as paved roads do...

Here cost is a plural verb (for the plural noun dirt roads) and do is "filling in" for cost (with a different subject, paved roads). Effectively, the sentence becomes

... dirt roads cost twice as much to maintain as paved roads cost to maintain...
