I choose E as well for parallel construction... "Nuclear fusion powers the Sun, etc... and merges the nuclei of atoms..."

Answer D is wordy and folksy :wink:

Will go with E. Good ||ism as well as all other options give a meaning that nuclear reactors merge the nuclei too.

'and merges' incorrectly lumps the merging of the nuclei as an item that nuclear fusion powrs. -> D,E are out.

A,B --> bad comparison. Need a 'do' at the back

C is the best choice.

C. Correct. Rather than is a correct idiom for comparison in this sentence; as is followed by a clause with a subject, nuclear reactors, and a verb, do; the comparison is clear and complete.

E. Illogical and awkward construction incorrectly makes merges the second verb of the restrictive clause and a separate action parallel to powers; comparison is awkwardly drawn; switch from nuclear to atomic is unexplained and unsupported.


joemama142000 gave the wrong OA in that thread.

Reviving old thread.....it is important to be clear on this questions. I was still confused and so couldn't help writing my point of view.

Nuclear fusion powers the sun…. (while/by) merging the nuclei. -> Correct

Nuclear fusion powers the sun… and merges the nuclei -> two separate actions are not required. Participal clause explain best how nuclear fusion works. So Incorrect.

clearly E can't be the answer.

It compares two actions against one.

'them' may refer to nuclei or stars.

that would have solved the problem if was placed before merges

But since it was not given I think only merging would be the option

Just read it like this "Nuclear fusion is the force that powers the Sun and merges the nuclei of atoms, unlike atomic reactors that split them apart" Think are they two separate actions? NO.

Now
"Nuclear fusion is the force that powers the Sun, merging the nuclei of atoms rather than splitting them apart, as nuclear reactors do." This explains that Nuclear fusion is the force that power the Sun by merging the nuclei. Makes more sense.

So it is "C"

I picked D based on the basis of parallel logic but was proved wrong.

OA is C

I ruled out E as it changes the "nuclear" in the original sentence to "atomic"

as mentioned in the subject, this is from OG (11th ed, # 104).
I was also puzzled by this question initially so decided to post here !

I just checked the previous threads on the same SC:

Here E was announced as the OA.

Firstly, we need to eliminate D and E.

By merging the Sun, the stars and hydrogen bombs with the merging of atmoic nuclei, we're trying to treat them as one compounded item that nuclear fusion drives. Assuming we group the Sun, the stars and hydrogen bombs as A, and we call 'merging the nucleir of atoms and not splitting them apart' as B, then we would have:

Nuclear fusion is the force that powers A and B as in nuclear reactors. --> that's to say nuclear fusion powers A and B, unlike reactors that doesn't power A and B. Not quite right...

A and B are out, because without the 'do', we're making a poor comparison.

i double checked the answer and it is "C" in OG.
It also mentions that rather than is a correct idiom for comparison in this sentence.

I am really perplexed now.
Last time we arrived at the conclusion that answer is E.
And the poster of this SC confirmed E as the OA.

Now OG says C is the answer.

In the previous discussion, Vivek had posted that :

In "C" it is not clear what the part of the sentence after "comma" refers to.
It can refer to whole sentence (merging the nuclei of atoms rather than splitting them apart) but it should refer to "splitting them apart"

This is what I also thought last time.

IMO, splitting the ...... refers to the how nuclear fusion powers the sun, stars + hydrogen bomb. The last part about the nuclear reactor is to say that the nuclear reactors operate the same way to power whatever they are supposed to drive.

By not using 'and', we seperate it from the list of objects driven by nuclear fusion, and set it as the way it generates energy to drives these objects.....

In any case, if you trust nobody, then trust the OG.

C.

The sentence would look like this if you insert E

Nuclear fusion is the force that powers the Sun, the stars, and hydrogen bombs, and merges the nuclei of atoms, unlike atomic reactors that split them apart

unlike - compares Nuclear fusion with atomic reactors, not correct. if it was something like unlike nuclear fission, it would have been correct.

also think usage of 'and' confusing and changes the meaning of the sentence. Sun, stars and hydrogen bombs are the examples which are powered by nuclear fusion, where as merging of nuclei atoms is more like a definition of nuclear fusion.
