(A) merging the nuclei of atoms and not splitting them apart, as in nuclear reactors

(B) merging the nuclei of atoms instead of splitting them apart, like nuclear reactors

(C) merging the nuclei of atoms rather than splitting them apart, as nuclear reactors do

(D) and merges the nuclei of atoms but does not split them apart, as is done in nuclear reactors

(E) and merges the nuclei of atoms, unlike atomic reactors that split them apart

'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.

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.

The biggest problem with E is that it compares Nuclear Fusion with Atomic Reactors?

Very late. But C it is.

The answer is C.
D and E get eliminated(and merges...) since it talks about Nuclear Fusion's another property ( and merges the nuclei of atoms ....), whereas it actually needs to mean the modus operandi of the Nuclear fusion, which is ok in A,B,C (merging). And out of those 3, C is the complete comparison.

The trick here is to notice that the listed nouns ends with "AND hydrogen bombs." When this un-underlined portion ends like that, you should know certainly that what comes in the underlined sentence shouldn't be a list anymore, therefore you can eliminate D and E instantely. You know that what will start after the comma will be a present participle. This should do the trick.

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 go with the OG’s OA and OE, simply because they are official ones. But the essence of the passage seems to be to compare nuclear fusion, a phenomenon, with nuclear reactor, just a device or shall we say, a chamber. The phenomenon rightly comparable to fusion is actually fission.

GMAT has highlighted that we shouldn’t compare apples with oranges. Isn’t it ironical that now a reaction is sought to be compared with a rector.

The bottom line is that with LOL for OG, C is the answer.

dont by obsessed with grammar, instead focus on meaning. i fail gmat again and now i try to apply e gmat approach.

look at choice a.
" as in nuclear reactors " mean as "nuclear fusion split in nuclear reactor" . this make no sense.
we have to know illogic thing and intended meaning when we read only original choice

C is correct

We need "merging" here as it the result of force is merging the nuclei

as nuclear reactors do
Correctly states the action done by nuclear reactors so "do" is essential here

Can you please explain why OA is C ?
I choose OA as E , I found it better

(E) and merges the nuclei of atoms, unlike atomic reactors that split them apart

The focus of the topic is the nuclear fusion that powers the vast bodies. The adverbial modifier precisely refers to the power, which merges the nuclei. The first modification ends there, and then in the second modification, the relative clause 'as nuclear reactors do' modifies the splitting of the atoms by the fabricated reactors.
The choice also uses. The correct idiom rather than compared to the 'instead of.'
E's problem stems from wrongly treating 'merger' as equal to powers although 'merger' is only the result of the 'powering,' which entails a modifier.

for me, a non native, it is hard to find out comma+doing or and+do is used. one way to test is ask myself
weather the action presented by doing must happen when the main action happen


the force power the sun and this powering can not happen without merging. merging, not and merge is correct, . choice d and e gone. this point is never easy to me.

in choice A, comparison is wrong, nuclear reactor is a second element of comparison not a adverb phrase. A is gone.

I do not know wheather "like nuclear reactor " is wrong? pls help

though many persons say that "like" at the end of main clause can work as "as...do" but I think that the main meaning of like is that it shows two subjects do the same action.
splitting them apart , like nuclear reactor
means that both force and nuclear reactor do the same thing, the splitting.

in contrast, "as" show that two actions is done in the same way

C means
force split them as nuclear reactor split.
both force and nuclear reactor split in the same way.
this is correct and intended meaning

so , at least choice b is ambiguous. nearly choice b offer incorrect meaning

the official questions is basic and very hard. only when we can give it full explanation, we can make the similar questions
