Is it A ?

[EDIT: ADDED EXPLANATION FOR MY CHOICE]

we need "that have" here. Only A and C have "that have".

in C -> fewer Carbon dioxide is plain wrong. A may not be perfect, but it is the best.

what is the OA ?

B for me :

A of comparable size, as well as emitting far less carbon dioxide gas and far fewer of the other gasses that have - not parallel in tense
B of comparable size, as well as emit far less carbon dioxide gas and far fewer of the other gasses having
C of comparable size, and also they emit far fewer carbon dioxide and other gasses that have - they is ambiguous
D that have a comparable size, and also they emit far fewer of the other gasses having - same as C
E that have a comparable size, as well as emitting far fewer of the other gasses having -- same as A

Horrendous question; but the answer seems to be A.
The others have grammatical errors.

A has a grammatical error too. None of these seem right. Probably a typo by mgmat.

A

less Vs Fewer - less CO2, CO2 cannot be measured so less should be used.

A of comparable size, as well as emitting far less carbon dioxide gas and far fewer of the other gasses that have

B of comparable size, as well as emit far less carbon dioxide gas and far fewer of the other gasses having - having??

C of comparable size, and also they emit far fewer carbon dioxide and other gasses that have - less vs fewer

D that have a comparable size, and also they emit far fewer of the other gasses having - having??
E that have a comparable size, as well as emitting far fewer of the other gasses having - having??

I vote for B. (this choice IMO best among all)

"They" in choices C and D seems not to have clear antecedent: it can be anything
A and E are out for "emitting" it should have been "emit" to keep //.

"as well as emitting far less carbon dioxide gas and far fewer of the other gasses that have been implicated in global warming" is a modifying phrase but I never saw "as well as" in modifying phrase. Now I should note that "as well as" also acceptable as modifying phrase:

Diesel engines burn as much as 30% less fuel than gasoline engines of comparable size, (as well as) emitting far less carbon dioxide gas and far fewer of the other gasses that have been implicated in global warming.
In that sense A should be ok.

Initially I felt that emit and burn are parallel. How ever having been at the end takes B out of contention. A remains

A for me

have been is the key for 3-2 strategy here. C has issues with pronoun reference in they

fewer gases(countable ) is correct so is less gas (non-countable )

I read this on some old post of gmatclub

Quote:
when you have "as well as" in your sentence then the verb following "as well as" need not be parallel with the verb before "as well as".


looks like this thing holds good in our sentence here ...

yes as well as means inaddition !!! hence i think ,as GMAT TIGER said
here if we just simply forget this (as well as ) for a moment and then read the sentence A sounds the best!!!

Also having ,having been are all wrong ,that have been implicated is correct

here if we look at the meaning then also its obvious that engines burn fuel emitting gases !!

so my doubt got clarified !!
thanks a tonne for the posts !!!

great posting :thanks :btw :btw :good :good
