Scientists at the Los Alamos National Laboratory have succeeded for the first time in mining heat from the Earth’s interior and producing energy on a commercial scale, enough for efficient generation of electricity and heating factories and homes.

A. and producing energy on a commercial scale, enough for efficient generation of electricity and heating - awkward and not parallel
B. and producing enough energy on a commercial scale for electricity to be generated efficiently and to heat - wrong parallelism
C. for energy production on a commercial scale, enough for generating electricity efficiently and to heat - awkward
D. to produce energy on a commercial scale, enough for generating electricity efficiently and for heating - parallel and conveys the meaning
E. to produce enough energy on a commercial scale for efficient generation of electricity and heat - awkward

why would u pick D? "have succeceed in mining and to produce" Wrong?

i am not sure between A and B

You just have seen it wrong there is no "and" recheck option D ........

Sorry for opening such an old thread. I am unable to conclude the answer.

I chose B. However, MGMAT and few other guys in GMATclub says its D. The OA is also not provided. Can someone please put some effort and let me know the OA?

+1 for D.

Difference between B and D is on the lines of

I know a way to finish the job.
Vs
I know a way for the job to be finished.

Clearly, the former sounds more correct.

I am not convinced with D because it seems that "enough of generating" is modifying the "Commercial scale".

Isn't "enough for generating electricity" here modifies "commerical scale" in choice D?

I prefer D because "in mining to produce" sounds more logical

Mining and Producing can't be parallel coz, Mining leads to production and these two are not independent events. hence D should be the answer

No OA hitherto? I prefer D. I think mining heat from the Earth's interior helps produce energy so B is incorrect.

Scientists at the Los Alamos National Laboratory have succeeded for the first time in mining heat from the Earth’s interior and producing energy on a commercial scale, enough for efficient generation of electricity and heating factories and homes.
A. and producing energy on a commercial scale, enough for efficient generation of electricity and heating --> Misplaced modifier. The modifier is modifying "commercial scale" where it should be placed near "energy". Also, "for generation of electricity" and "heating" are not parallel. It should have been ""for generating electricity and heating ". This sentence also perverts the intended meaning. The sentence should have been "Scientists at the Los Alamos National Laboratory have succeeded for the first time in mining heat from the Earth’s interior to produce energy on a commercial scale,...."
B. and producing enough energy on a commercial scale for electricity to be generated efficiently and to heat--> again it should be "to produce" and the underlined parts are not parallel.
C. for energy production on a commercial scale, enough for generating electricity efficiently and to heat--> underlined parts are not parallel.
D. to produce energy on a commercial scale, enough for generating electricity efficiently and for heating--> looks good. Underlined parts are parallel and "and" replaced by "to".
E. to produce enough energy on a commercial scale for efficient generation of electricity and heat --> underlined portion is wrong. It should be a noun / noun form (gerund) - "heating"
It should be D. Though IMO is B, but still B has conspicuous parallelism issues!

A. and producing energy on a commercial scale, enough for efficient generation of electricity and heating - awkward and not parallel
B. and producing enough energy on a commercial scale for electricity to be generated efficiently and to heat - wrong parallelism
C. for energy production on a commercial scale, enough for generating electricity efficiently and to heat - awkward
D. to produce energy on a commercial scale, enough for generating electricity efficiently and for heating - parallel and conveys the meaning
E. to produce enough energy on a commercial scale for efficient generation of electricity and heat - awkward

Answer D - uses the parallelism correctly

I think the catch here is to recognize the progressive and non progressive forms !!!!! Another trap question @#\$%^&* !!!!!!

mining heat from earth interior "to produce" - correct idiomatic style
D - use of "to" + for generating and for heating

A and B are out because in producing is unidiomatic. It should be to produce.
C changes the meaning altogether, so C is out.
E has parallelism issue. For generating and FOR HEAT is incorrect.

Left with D which is the right answer.
