[Reveal] Spoiler: 'My Doubt...Please Answer my doubt on comparision'
I sometimes get confused with these kinds of comparision.
Can someone please tell me how is dirt roads maintenance compared correctly to paved roads maintenance in B and not in other? How can we verify if something is being compared correctly here? Is there a substitution method I can use to verify?


I understand that in A there is incorrect comparison between dirt roads & paved roads since paved roads maintenence is compared to dirt roads costs...

But in C,D,E i am having hard time finding comparison error ...


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

(A) dirt roads cost twice as much as maintaining
paved roads....... direct road cost vs maintaining paved roads... wrong
(B) dirt roads cost twice as much to maintain as
paved roads do..... Correct comparison .. verb 'do' at the end is very important.. without this 'do' the comparison is incomplete. U can also read it like " as X as Y' ....
(C) maintaining dirt roads costs twice as much as
paved roads do ..... maintaining dirt roads cost vs paved road cost.
(D) maintaining dirt roads costs twice as much as it
does for paved roads..."it" pronoun has no clear reference. I liked the sentence better than B , except for 'it'
(E) to maintain dirt roads costs twice as much as
for paved roads........ same as C
