Question

In 2003, apartment rental costs in most neighborhoods of Brooklyn rose almost  so high, and in certain neighborhoods even higher than what they did  in Manhattan.

A. so high, and in certain neighborhoods even higher than what they did
B. so high, and in certain neighborhoods even higher than, those
C. as high, and in certain neighborhoods even higher than, those
D. as high as, and in certain neighborhoods even higher than, those
E. as high as, and in certain neighborhoods even higher than what they did

______________________________________________________________________
Why not choice E? Normally, if there is a comma before the word"and", the following sentence should be independent sentence. But why does incomplete sentence followed "and"?

Thanks,

IMO D

best way to tackle these question involving commas is to treat them as separate sentences. there is 2 levels of comparison -

D - 
1) apartment rental costs in  neighborhoods of Brooklyn rose  almost as high as  those  in Manhattan (correct comparison)
2) apartment rental costs in  certain neighborhoods  even higher than  those

above requirement is not satisfied in any of other choices.....

amit2k9 · Answer

as high as is correct comparison.

D and E remain.
In E usage of they is wrong since it doesn't has a clear antecedent. It can refer to neighborhood too.

D.

But What about the word "and", the sentence followed by "and" supposed to be independent and complete sentence if there is a comma before "and".

+1 D

Idiom:
...as (adj./adv.) as....
"Those" makes a copy of rental costs. "They" is wrong because it refers to "rental costs in most neighborhoods of Brooklyn".

B. as high as, and in certain neighborhoods even higher than, those
idiomatic as... as; even... than; and those talks about costs, has to be plural.

If idioms are out of the GMAT.. why people are still posting idioms questions on the forum?

Can you please check the original sentence I feel there is a "to" missing in the un-underlined part:

In 2003, apartment rental costs in most neighborhoods of Brooklyn rose   to   almost so high, and in certain neighborhoods even higher than what they did in Manhattan.

D says that the rental costs are same as(or higher than those in) Manhattan.
E says that the rental costs grew at the same rate as the rate in Manhattan.
