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.
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
C of comparable size, and also they emit far fewer carbon dioxide and other gasses that have
D that have a comparable size, and also they emit far fewer of the other gasses having
E that have a comparable size, as well as emitting far fewer of the other gasses having

Plz. explain

IMO C

Firstly, of comparable size is correct. Eliminate D,E.
A, B are awkward because of 'and far fewer of the other gasses' it should be 'than'
What if i have not yet beat the beast, I know i will beat it!!!!!!!!

BURN // EMIT

'That' correctly modifies gasses

imo C

Burn is parallel to emit, hence between B and C

I eliminate C because they could refer to gasoline engines or diesel engines.

What does "they" in C refer to?

In B, the other problem i found was less and fewer. "fewer than what?"

But i thought B is better answer as it is referring to diesel engine and hence B.

In C isn't "they" ambiguous?

"They" can refer to diesel engines or gasoline engines?

I would choose B, but not 100% sure the answer.

Diesel engines is the subject of the first clause.. doesn't the pronoun 'they' modify the subject of the first clause?

However, I do agree that C is incorrect because it uses 'fewer' which is used for countable objects. C should have used 'less' instead.

@Rohan,

I think ponoun refers to the its antecedent.

There are 2 nouns in the first clause
diesel engines and gasoline engines and hence they can refer to either.

What is the source?

Burn and emitting is not parallel.

Only reason why B can be eliminated is the verb form "having been"

Cant understand?

Ok my vote goes for A

D and E are out 'engines that have a comparable size' is wordy and awkward. Its better to use 'engines of comparable size.

Also gasses 'having been implicated in global warming' is incorrect.

So that brings down the options to A and C

Now C says 'emit far fewer carbon dioxide'. Isn't Carbon Dioxide uncountable??? So we need less not fewer.

i read in an OG SC explanation that 'as well as' should be used when comparing two things. this helped me narrow this down immensely.

Sorry for the post...

I agree with Schumi...A is correct if you look at the "FEWER & LESS" part, but BURN and EMITTING are not parallel at all!! That would be extremely stupid!!

What is the source?
