This is all about being supremely literal with comparisons, as we'll discuss in this week’s YouTube webinar. And I don't think that anybody really loves comparisons, so… I dunno, try to enjoy this one anyway.

Quote:
(A) dirt roads cost twice as much as maintaining paved roads

This is literally saying that dirt roads themselves cost more than maintaining paved roads. That doesn’t work: we either need to compare “maintaining dirt roads” to “maintaining paved roads” or we can compare the two types of roads. But (A) makes no sense in its current form.

Quote:
(B) dirt roads cost twice as much to maintain as paved roads do

This sounds pretty good! The key here is that the word “do” can replace a verb phrase – and in this case, “do” replaces “cost… to maintain.” So this is saying that “dirt roads cost twice as much to maintain as paved roads [cost to maintain].” Great, that makes sense. Let’s keep (B).

Quote:
(C) maintaining dirt roads costs twice as much as paved roads do

This is lamentably subtle. Keep in mind that “do” replaces a verb phrase – and “maintaining” is a noun (gerund) in this case, and definitely not a verb. (For more on –ing words, check out this article: https://gmatclub.com/forum/experts-topi ... 39780.html.) So this is literally saying that “maintaining dirt roads costs twice as much as paved roads [cost].” Now we’re comparing the cost of maintaining dirt roads with the cost of paved roads themselves, and that doesn’t makes sense.

Tricky, but definitely wrong. (C) is gone.

Quote:
(D) maintaining dirt roads costs twice as much as it does for paved roads

The “it” jumps out at me here. If we’re being charitable, I suppose we could accept the idea that “it” refers back to “maintaining”, since “maintaining” is a noun. So we have “maintaining dirt roads costs twice as much as [maintaining] does for paved roads.” Really? I guess that’s not totally illogical, but it’s a muddy mess, and it’s a whole lot less clear than (B). So (D) is out, since (B) is undoubtedly clearer.

Quote:
(E) to maintain dirt roads costs twice as much as for paved roads

I don’t see any reason why we would use the infinitive “to maintain” as a noun here. That’s not something that you’ll see very often in correct answers on the GMAT. I’m not 100% certain that it’s absolutely wrong, but it’s definitely inferior to (B).

Just as importantly, if we’re going to use the infinitive “to maintain” as the subject of the clause, then it’s only going to makes sense of the comparison is parallel. Something like “to maintain dirt roads costs twice as much as to maintain paved roads” would at least be parallel. (E) in its current form doesn’t make any sense, since “to maintain dirt roads” is compared with just the prepositional phrase “for paved roads.”

So (B) is our winner.

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.

The structure of comparison "X as much as Y" where X and Y must follow the same form.

Hence only B satisfied.

(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

The purported meaning of the sentence in my opinion 'dirt roads are more costlier than paved roads in terms of maintenance.'

It is the cost of maintenance that we need to compare and not the dirt roads to paved roads.

Option A seems to mean 'the cost of dirt roads is twice the cost of maintaining paved roads'. Hence its wrong.

Option B in my opinion is in the correct format of the structure X as much as Y.

Option C the same error as seen in A but with a reversal. This option purports to mean that maintaining dirt roads is twice as costly as paved roads cost.

Both of options D and E do not have the correct format of the structure 'X as much as Y'

I believe it should be B. But you never know... Upto the experts...

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.

Intended Meaning : Maintaining Dirt Roads costs twice as much as Maintaining Paved Roads. This is the intended comparison implied from the original sentence.

(A) dirt roads cost twice as much as maintaining paved roads (do)
Incorrect. Here, the cost of construction of the dirt roads is compared with the cost of maintenance of the paved roads. This is not the intended meaning.

Understanding the structure : Maintaining Paved Roads -- Maintaining (Gerund/Action Noun) Paved (Adjective) Roads. So, here maintaining is specifically referring to the paved roads.
Dirt roads cost : here, the implied meaning is the cost of construction of the dirt roads.

(B) dirt roads cost twice as much to maintain as paved roads do (do -- cost to maintain)
Correct. In terms with the intended meaning.

(C) maintaining dirt roads costs twice as much as paved roads do
Incorrect. Here, the cost of maintenance of the dirt roads is compared with the cost of construction of the paved roads. This is not the intended meaning.
One More Important Thing to Note Here : Only VERBS or PREPOSITIONS can be ellided, nothing else.
If someone thought, option C as,
maintaining dirt roads costs twice as much as maintaining paved roads do (costs). Then that is INCORRECT for the reason mentioned above.

(D) maintaining dirt roads costs twice as much as it does for paved roads
What does "it" refers to here? It does not have a logical antecedent. Therefore, Incorrect.

(E) to maintain dirt roads costs twice as much as for paved roads
The comparison is not very clear in this option. What "for paved roads" is referring to? Choice B is much better than this option choice.

in comparision pattern, the author can make a lot of confusions by make many structures which is incorrect. the key to counter this game is simple.

the two compared elements in the two parts of comparision must be in the same role in each of the part of comparison.
keep this point in mind and be comfortable finding the choice that met this point.

so, look for two compared element and find the choiice in which the two are in the same grammatical roles.
