I pick D.

Did anyone else think that "to" was critical in the construction of the sentence?

"and" is incorrect here because interior must be followed by a comma, for "and" to be in play.

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.

Can someone correct me?

. 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 no errors
B. and producing enough energy on a commercial scale for electricity to be generated efficiently and to heat - changes the meaning of the sentence
C. for energy production on a commercial scale, enough for generating electricity efficiently and to heat - changes the meaning of the sentence
D. to produce energy on a commercial scale, enough for generating electricity efficiently and for heating -changes the meaning of the sentence
E. to produce enough energy on a commercial scale for efficient generation of electricity and heat - changes the meaning of the sentence

IMO answer is A
the sentence conveys that the scientist has suceeded in mining and producing energy enough for electricity and heating

I think I agree with prateek that there is a modifier issue in the A. commercial scale,....
I hate to do this but I change my poll to B

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.

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

i am not sure between A and B


it should be ..
have succeceed in mining "heat" from "Earth's interior" to produce "energy"..
I don't see any problem with this statement.

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

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)

IMO A

as
Q: 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.

words in bold should be in parallel, if u look on other choices
B) and to heat is not in parallel
C) same as B
D)to produce...., heating are not parallel
E) mining....to produce.....and heat are not in parallel
Remember it's "mining heat", which means mining is a verb
So the correct answer is A

Hope it helps!
Please! correct me if I am wrong as I am not an expert here.
Peace! :)

In a simpler mode - Scientists have succeeded in mining heat to produce energy, enough for generating...and for heating...

In E, "for efficient generation of electricity" is not parallel with "heat factories and homes"

In D, "for generating electricity efficiently" is parallel with "for heating factories and homes"

Hope this helps

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

The word and is used a co-ordinating conjunction which is used to connect independent idea's. Here , the two things that scientists do are not independent. They are successful in generating heat from inside the earth to produce electricity. Clearly A and B are out. C is out for ambiguity. Now D clearly maintains parallelism. Hence , it wins.

As Daagh said you could have looked for || and picked D and moved on.

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!

this is a very good || ism question.

I had gone thru one of RON's videos and he had taken this question as an example to explain ||ism.

The main situation here is to get idea what the question means.

1)Scientists ...... have succeeded for the first time......"to" produce energy on a commercial scale

now the question arises for what???????

the idea conveyed following this should be parallel
2)it means that the energy produced will be used "for generating electricity" and" for heating" factories and homes.

So option D is concise and conveys the idea perfectly.


hope it helps.
