Re: Even in this age of conservation, cooking ranges that [#permalink]

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

ankit0411 wrote: Qassam wrote: 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... kudos

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
What should be the correct answer to this question. ?
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. Consider kudos if my post helps!!! Archit
