options C & D are out since they start with 'which' which when incorporated in the sentence makes the meaning ambiguous as in which form of fuel produces heat more efficiently ? Fossil fuel or magnetic resonance .
Option e is grammatically incorrect
Option B wins over A because of the 'does'at the end of the sentence ...hence B it is

Let me disagree with B, IMO is D

There is no S-V agreement error in D. Produce is the verb for "Those that rely on magnetic resonance" Plural.

Plus, there is a meaning problem, as natural gas is a fossil fuel. Also the sentence intends to make a contrast between the age of conservation and the means people are using to cook. Stating that Magnetic resonance is more efficient emphasizes such contrast.

Experts, your input will be really appreciated in this one

Cheers

1. Which refers to MR (singular); not those (ranges) that rely on MR. We cannot take it to refer to a noun that is not just in front. The touch rule of which is quite clear about it. So the plural produce is a wrong verb and D suffers from S-V mismatch.
2. If a contrast is sought to be made out between the age of conservation and the means of cooking, then, that is basically wrong. We must make a comparison and contrast between only parallel things. An age cannot be contrasted with a means. So D can never make it.

To clarify my doubts on "which," is it possible to read the sentence in the following way:

Even in this age of conservation, cooking ranges that consume fossil fuels are far more common than those [implicit: those cooking ranges] 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

Based on this, answer is D. "Which" refers to "Those cooking ranges that rely on magnetic resonance," not "magnetic resonance," and therefore "produce" agrees with the implies "cooking ranges" rather than mismatches with "magnetic resonance."

Basically, how far can into the previous clause can a which statement extend,

@banaorange

Can which in this case refer to ranges? There are two choices that use, ‘which ‘namely C and D. Let’s insert choice C and D in their relevant places and see.

C. Even in this age of conservation, cooking ranges that consume fossil fuels are far more common than those [implicit: those cooking ranges] that rely on magnetic resonance, which produce heat more efficiently than natural gas--- So by taking ‘which’ to refer to cooking ranges, the choice says that cooking ranges (kind of gadgets) produce heat more than natural gas (a planetary resource)

D. Even in this age of conservation, cooking ranges that consume fossil fuels are far more common than those [implicit: those cooking ranges] that rely on magnetic resonance, which produce heat more efficiently than natural gas does --- same comparison error as in C

How far away can the relative pronoun,’which’ go deep into the preceding clause. Here is what I picked up from some forum writings.

Quote:
According to Manhattan GMAT, in general, a noun modifier should touch their nouns; however there are 4 exceptions to this case:
1. A "mission critical" modifier falls in between
2. A very short predicate falls between, shifting a very long modifier back
3. A short non-essential phrase intervenes and is set off by commas
4. The modifier is part of a series of parallel modifiers, one of which touches the noun
Quote:


Where to find this quote in MGMAT, I am not sure, since I do not have the MGMAT Guide

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.


ankit ...well explained...

I feel it should be Option D.

I couldn't understand the construction of this sentence request forum members to help me understand.


C and D cannot be correct answer because it uses plural form"produce". E makes a faulty comparison same goes with A. Hence the answer must be 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



Hi,
I think D is correct.
Now Why ?
What produces better heat ? is it Magnetic resonance or Natural Gas.
It's Magnetic resonance.
so the use of "which" is justified. Hence D

Secondly natural gas is nothing but Fossil fuel. And the statement states that cooking ranges which use magnetic resonance, produce better heat than Natural Gas but people still rely on ranges that consume fossil fuel.

Which is a wrong Modifier
Eliminate C D

In A and E action (Production of gas is compared to noun Natural gas, Wrong comparison)
Eliminate A and E.


B sounds ok, as does is used to compare action.

I will grade this question under Poor quality category all choices have error.
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--> modifier is modifying entire preceding clause instead of magnetic resonance
B. producing heat more efficiently than natural gas does --> modifier is modifying entire preceding clause instead of magnetic resonance
C. which produce heat more efficiently than natural gas---> S-V error should be which produces
D. which produce heat more efficiently than natural gas does --> S-V error should be which produces
E. much more efficient at producing heat than natural gas ---> absolute phrase.-- error in comparison X is much more efficient at producing Y than Z (does)

Good one , here is my atempt -

Even in this age , cooking range are more common than magnetic resonance ....
Producing heat more efficiently than natural gas <--------- Must logically refer to cooking ranges.

A. producing heat more efficiently than natural gas

Cooking gas more efficient than natual gas :cry: Not good..

B. producing heat more efficiently than natural gas does

Cooking gas producing ----> more efficiently than ------> natural gas does ( Comparing Actions ) , seems ok :-D

C. which produce heat more efficiently than natural gas

which referring to Resonance , wrong :oops:

D. which produce heat more efficiently than natural gas does

whcih referring to Resonance :oops:

E. much more efficient at producing heat than natural gas - Completely wrong.... :twisted:

Hi daagh

In option C and D you have mentioned that S-V is wrong, why can't "which" refer to "Those" ?

Thanks in advance!

daagh wrote:
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.

Shouldn't verb "ing" form in option B modify the preceding clause? I was under assumption that "ing" form gives us either result set of preceding clause or additional information of preceding clause. So not sure how can this construction be correct?
However, other options do have some serious errors.

Yes, I have the same concern as yours. The modifier producing heat more efficiently than natural gas seems to refer to the subject of the preceding clause cooking ranges that consume fossil fuels or the preceding clause.... cooking ranges that consume fossil fuels are far more common than those that rely on magnetic resonance... as a whole as you pointed out.

As Daagh has mentioned in a previous post, not using a comma before producing would have been appropriate since in that case the modifier would refer to those that rely on magnetic resonance.
