Diesel engines burn as much as 30 percent less fuel than gasoline engines of comparable size, as well as emitting far less carbon dioxide gas and far fewer of the other gases that have been implicated in global warming.

(A) of comparable size, as well as emitting far less carbon dioxide gas and far fewer of the other gases that have
(B) of comparable size, as well as emit far less carbon dioxide gas and far fewer of the other gases having
(C) of comparable size, and also they emit far fewer carbon dioxide and other gases that have
(D) that have a comparable size, and also they emit far less carbon dioxide gas and other gases that have
(E) that have a comparable size, as well as emitting far fewer carbon dioxide and other gases having

My analysis:

Gasoline engines that have a comparable size is wrong. SO, I eliminated D and E.

They in the option C is ambiguous.

Having in the option B is wrong.

I am not convinced with the answer A.

"As well as Verbing" has been used here as the modifier. It is right?

Thanks.

Your analysis is pretty good. I just see it as,
Diesel engines burn....., .....emitting far less.. - Comma + ING modifier -> Usual Adverbial modifier
Though I am not sure how Preposition "as well as" is affecting the grammar over here when placed before Adverbial

Looks like this question treads on some shaky grounds: https://www.manhattangmat.com/forums/post13579.html

The only take away I can see are that although "as well as" is a conjunction, it is not necessarily a parallel marker, and that "as well as + present participle" is an acceptable form on the GMAT.

I think I need some more work on my understanding of gerund as well. I am not quite satisfied with the general rules as presented in MGMAT SC book.

After further evaluation, I think that "as well as verb-ing" must be a GMAT only thing, because verb in present participle must be preceded by a BE verb as in, "as well as is emitting" or in another words, "and is emitting".

Now I am really confused.

(I think in option C, They refers- Diesel engine and in this case this is the best choice)

as per ron
"...as well as VERBing" is an acceptable construction

IMO A.

In SC questions the point is to find the best among the 5 choices and the best answer may not be the grammatically perfect. The best answer will be best fit based on gmat grammar. :)

Well, clearly emitting is not a gerund in this construction, but it isn't following the form of standard verb in the present participle either. So I guess this is either a fluke or GMAT allows this construction when it is following as much as.

I am glad I came across this question, and now I know a weird exception to the BE + verb-ING form on GMAT.

well,all arguements here are valid
but i actually made 2/3 split first with have vs having
having been implicated should awkward to me...
so i cross off B and E
C is out because of fewer
A and D close
I chose A as in D reference of 'they' is not clear

Your analysis is same like that of mine.

I also have a question regarding emitting after as X as

Today when I revisited the question, I approached in the following way.

Diesel engines burn as much as 30 percent less fuel than gasoline engines of comparable size, as well as emitting far less carbon dioxide gas and far fewer of the other gases that have been implicated in global warming.

(A) of comparable size, as well as emitting far less carbon dioxide gas and far fewer of the other gases that have - Correct

(B) of comparable size, as well as emit far less carbon dioxide gas and far fewer of the other gases having - having been is actually passive, out

(C) of comparable size, and also they emit far fewer carbon dioxide and other gases that have - fewer is wrong here, we need less

(D) that have a comparable size, and also they emit far less carbon dioxide gas and other gases that have - less carbon dioxide gas is fine, but you can not use less for other gases, since you can count the number of gases. Out

(E) that have a comparable size, as well as emitting far fewer carbon dioxide and other gases having - same as C

A/B/C/E - all have 'fewer' for uncountable carbon dioxide....is the usage correct. Can we not drop these options just on that basis. Pls help

In A where do you have fewer for uncountable carbon dioxide. in A we have less 'quantity' of carbon dioxide. You can not count 1 carbon dioxide, 2 carbon dioxide and so on.

You have fewer for the number of gases. We can count different gases. E.g. there are three gases such as oxygen, carbon, and helium.

In the given sentence quantity if CO2 is measured, on the other hand number of other gases are measured. Therefore, we have less and fewer respectively.

HTH!!!!
