Hi Experts,
Could anybody look into the question:
For me B should be correct as the phrase 'mining heat from the Earth’s interior' and 'producing energy on a commercial scale' are parallel.
[Reveal] Spoiler: OA

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!

Guys! plz!! explain why D? I think "and for heating" is better option than "and heating". Any other detailed explanation would be great.

Parallelism is between "for generating electricity" and "for heating"

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"

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.

Just curious in this sentence the absence of comma makes a difference on the intended meaning of the sentence? Can someone provide an analysis on that aspect. Thanks!

B. and producing enough energy on a commercial scale for electricity to be generated efficiently and to heat

D. to produce energy on a commercial scale, enough for generating electricity efficiently and for heating
E. to produce enough energy on a commercial scale for efficient generation of electricity and heat[/color]

This is a tricky parallelism question or meaning based question depending on how you look at it.

When you read this sentence you need to break down to understand what did Scientists succeeded for the first time -
I) in mining heat from the Earth’s interior
II) producing energy on a commercial scale

Did they do both of the above noted items for the 1st time? As you re-read you'll note that I and II are not parallel but more of I leads to II - Hence cross of A & B since we don't need an AND between I and II

The later part of sentence need to be looked at whether the phrase captures the effects/results of the earlier statement
III) electricity to be generated efficiently
IV) heating factories

This later part describes the effects of the earlier phrase so it requires ,verbing modifier and III and IV capture the effects so they need to be parallel - Hence cross of C and E

Hope this helps

I think this can solved with intended meaning approach. The scientists produced energy on a commercial scale but not for the first time.

A. and producing energy on a commercial scale, enough for efficient generation of electricity and heating - Incorrect due to reasons stated above.
B. and producing enough energy on a commercial scale for electricity to be generated efficiently and to heat - Incorrect due to reasons stated above.
C. for energy production on a commercial scale, enough for generating electricity efficiently and to heat - Incorrect. Lack of parallelism in the phrase "enough for generating electricity...."
D. to produce energy on a commercial scale, enough for generating electricity efficiently and for heating - correct parallelism in the phrase.
E. to produce enough energy on a commercial scale for efficient generation of electricity and heat - Incorrect. Lack of parallelism.

B. and producing enough energy on a commercial scale for electricity to be generated efficiently and to heat
C. for energy production on a commercial scale, enough for generating electricity efficiently and to heat
D. to produce energy on a commercial scale, enough for generating electricity efficiently and for heating
E. to produce enough energy on a commercial scale for efficient generation of electricity and heat

For me B should be correct as the phrase 'mining heat from the Earth’s interior' and 'producing energy on a commercial scale' are parallel.

Its D

As you have asked why B is incorrect ??

Reason is : when evr you look for parallelism , always check whether things which you are making parallel makes sense with the subject.
Example in this sentence B - Mining & producing are parallel to each other but, ask yourself in what scientist have succeed ,
They succeeded in mining heat ffrom earth's interior , but to produce heat for commercial purpose is not what scientist were looking for !!

that's why B is wrong !!!

Scientist were interested in mining heat !!

Regards
ST

Good meaning based parallelism question....where trick was to identify the scientist succeeded ...in mining and generating (where producing and succeeded cannot take place at the same time.
Hence D.

I think D is the right answer.

'have succeeded' is the verb used for main action
As a general rule, all the direct consequences or supporting clauses have -ing modifiers in them.
