First, let’s clear a few things. ,
1. Natural gas is a fossil fuel; So there can not be a comparison between fossil fuel and NG
2. First comparison is between cooking ranges that use fossil fuels and cooking ranges ( denoted by the pronoun those) that uses magnetic resonance (MR)
3. The second comparison is between the heating efficiency of MR and that of natural gas( a fossil fuel)
4. ‘Producing heat more efficiently than natural gas’ has to modify MR ranges rather than NG’s ranges. The end of the passage makes it clear.

A. producing heat more efficiently than natural gas --- faulty comparison between ranges and a fuel. Also may mean that MR produces heat more efficiently that it produces NG

B. producing heat more efficiently than natural gas does;---- the verb does make it clear that the comparison is between the production efficiency of MR over NG; best among the lot.
C. which produce heat more efficiently than natural gas ---- which produce – S-V mismatch; faulty comparison
D. which produce heat more efficiently than natural gas does --- S-V mismatch
E. much more efficient at producing heat than natural gas ---same problem as in A.

Hi
I will try to explain why 'B; is the answer.
whenever you see 'which', it refers to the noun before 'which', in this case the noun before 'which' is 'Resonance', so if we say resonance produce heat more efficiently than natural gas, it sounds incorrect.
hence options c and d go out.
option E is also wrong, as we dont know what is 'much more' referring to.
We are left with options A and B.
In A we are comparing the heat produced by fossil fuel to Natural gas.
this is wrong as we are not comparing the right things.
In B, we are comparing the heat produced by fossil fuel to heat produced by natural gas.This is the right comparison, hence is the answer

Thanks Aman ..i nearly understood .the explanation, because i was comparing resonance to natural gas.

Any tip how to spot what is being compared to what in a sentence?

as here i was going in the wrong direction by comparing resonance with the natural gas though the actual comparison was between Fossil fuel and natural gas.

Even in this age of conservation, cooking ranges that consume fossil fuels are far more common than those that rely on magnetic resonance, producing heat more efficiently than natural gas.

A. producing heat more efficiently than natural gas
B. producing heat more efficiently than natural gas does
C. which produce heat more efficiently than natural gas
D. which produce heat more efficiently than natural gas does
E. much more efficient at producing heat than natural gas

Which always modifies the subject / noun immediately preceding it. We need to compare coking ranges which use fossil fuel to cooking ranges which use magnetic resonance.

D & E compares coking ranges which use fossil fuel to magnetic resonance. - wrong options.

A compares cooking ranges which use magnetic resonance to natural gas. - wrong option
E compares efficiency of cooking ranges which use magnetic resonance to natural gas. - wrong option
Correct option - B

i would go with B. Producing creates a new clause, which is needed here.

I don't agree with the explanation for B being the answer. if B is the answer we are comparing "cooking ranges" with natural gas. I think the comparison should be between "magnetic resonance" and "natural gas". In my humble opinion the comparison is incorrect. But at the same time D can't be the answer because of S-V agreement issue. "magnetic resonance, which produce heat more efficiently than natural gas does". The produce should be produceS.

I believe there is an issue with the question. What is the source?

Arundas,
Yes , you are right -it's a comparision question. However, the comparision is between cooking ranges those use fossil fuel and those use natural gas
"ing" verbs modify the subject . "producing" is modifying " the cooking range that use fossil fuels".

Has to be B. While D is tempting, it screws up on produce.

It should be which produces not which produce. Hence B is most right.

I am still not very clear the changing meaning between A and B. I kind of guess it but have not yet understand the concept fully. Can any one do a more throughout explanation please? Thank you.

I don't think any of the answers are right! A can't be right because producing modifies the whole clause preceding it, which makes the comparison nonsensical. D has an S-V problem, produce is plural, while it should be singular.

the Verb+ing form modifies the preceding entire clause and hence gives you the correct meaning.

Where as, if you read carefully, the options with "which" actually tend to distort the intended meaning of the original sentence.

"Even in this age of conservation, cooking ranges that consume fossil fuels are far more common than those that rely on magnetic resonance, producing heat more efficiently than natural gas"

We want that cooking ranges ( use magnetic resonance ) are producing heat more efficiently than natural gas

the use of which changes the meaning of the above sentence.

Hi,

In option B, is the verb+ing modifier not modifying the cooking ranges, as ver+ing modifier after comma modifies the subject of the previous clause.

I believe for option B to be right, producing should follow magnetic resonance without comma.

A clause without a comma before - producing -would be most ideal; but unfortunately the comma is there. But it is at least ok as far as comparison is concerned.
That is the reason I said B is the best among the lot. Others are having more serious errors.
