Answer is D. For generating & for heating must be parallel.

I think the catch here is to recognize the progressive and non progressive forms !!!!! Another trap question @#$%^&* !!!!!! Mining heat from X to prduce Y "and" --> incorrect here. See why "and" is inappropriate here have succeeded for the first time in mining heat from the Earth’s interior and producing energy on a commercial scale = succeded for first time in doing X and doing Y. above sentence is gramatically correct.. but logically doesn't make sense. it means first time producing energy on commerical scale but that's not intention of author. ..[ energy might be produced on commerical sacle by other methods ...] first time in doing X from Z to product Y. I hope it clear. Between D and E.. D looks better. _________________ Your attitude determines your altitude Smiling wins more friends than frowning Senior Manager Joined: 04 Aug 2008 Posts: 377 Followers: 5 Kudos [?]: 34 [0], given: 1 Re: GMATprep SC : Scientists [#permalink] ### Show Tags 26 Sep 2008, 14:14 why would u pick D?

Another trap question @#$%^&* !!!!!!

The meaning of the sentence is important here. Its the mining of heat from the earth's interior that will lead TO production of energy on a mass scale. The two activities are interlinked, and not separate activities as indicated in the original sentence.

A. "and producing" changes the meaning of the sentence. "enough for efficient generation of electricity" is wordy and unclear
B. "and producing" changes the meaning of the sentence. "for electricity to be generated efficiently" and "to heat" are not parallel
C. "for electricity to be generated efficiently" and "to heat" are not parallel
D. Correct
E. "..for efficient generation of electricity and heat factories and homes" is incorrect

do we have OA and where this question came from

Actually, we dont know are those scientist succeeded in mining to produce or in mining and producing

they have to mine enough in order to produce enough

so

mining and producing enough as in B

Why did you determine that "for electricity to be generated efficiently" and "to heat" must be parallel in (B)?
"to be generated efficiently" is obviously parallel to "to heat".

Well, the way I see things is like this:

Scientists have succeeded ... TO PRODUCE (which means a, b and c are instantly out of the question). "In mining", IMO is not the predict of the scientists, but something else. Hence, this sentence needs a predict. A,b and c do not include a valid predict

D,E are the winners. The way I saw the solution is in the word "heat" or "heating." Heat cannot be produced for factories and homes but heating. Therefore, the correct answer is (D)

Would go for B as mining & producing are parallel.
Please post the OA to make it understand.
