Parallelism

[dj_vinayak]

Although few would disagree that small classrooms of a maximum of 15 students are ideal environments in which to educate the young, financially strained counties point out that small classrooms cost twice as much as maintaining regular sized classrooms.

A. small classrooms cost twice as much as maintaining regular sized classrooms.
B. small classrooms cost twice as much to maintain as regular sized classrooms do.
C. maintaining small classrooms cost twice as much as regular sized classrooms do.
D. maintaining small classrooms cost twice as much as it does for regular sized classrooms.
E. to maintain small classrooms cost twice as much as for regular sized classrooms.

I dont agree with the answer . I would go with D.

Acc to the source

The best answer is B. This sentence compares the cost required to maintain two kinds of classroom. B, the best choice, preserves parallelism in the comparison as well.

IMO B

D : it is ambiguous. 'It' can refer back to a noun only, it can not refer back to the action 'maintaining'

Hmm,never thought of 'it' like that.

I guess thats the correct reasoning ,thanks.

IMO B

D : it is ambiguous. 'It' can refer back to a noun only, it can not refer back to the action 'maintaining'

What is wrong with " C"

Option clearly gives a comparision maintaining X as well as Y do.

C is not parallel

maintaining small classroom cost ...
<maintaining> regular sized classrooms do --> now it is parallel

Tense used - "DO" is wrong IMO

B is correct; however, I think , had the option B had not a 'do' at the end, then also it would have been correct.

Pl. suggest.....

ansumania,

do is must .

1st point :
as is used for a clause - so verb is must
like is used for nouns

2nd point :

see the meaning of the sentence :

small classrooms cost twice as much to maintain as regular sized classrooms .

without 'do' it seems incomplete.

It reminds me of below OG Question. Nicely transformed into a new sentence by this source..

If you have finished OG then you should never miss this question.

hi,

I guess as can also be used for a noun if as is used as preposition.

Again, the sentence that you wrote above , it seeems perfectly fine to me. Am I missing sth? Pl. advise.

[paes]

as is not a preposition here.

Actually as can be used by multiple ways but here 'as' is not a conjunction.

as is used to compare clause. so do is must.

Received a PM asking me to respond on the "as" vs. "like" issue. I would be happy to, but you need to cite the source (author) of the question first. Let me know when you do!
