Nuclear fusion is the force that powers the Sun, the stars, and hydrogen bombs, merging the nuclei of atoms and not splitting them apart, as in nuclear reactors.

(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 reactor.

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

(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

Hi daagh,
My understanding was 'rather than' is always used to show preference and instead of means in place of and does not show preference ?
If my understanding is correct, isnt instead of more suitable here?
Please advise

Thanks in Advance

One possible reason is that the choice wants to assert and contrast the superiority of 'merging' over 'splitting' as merging is a mega event etc. while splitting is not( comparatively)
You see, when we use one in the place of another, they should be truly interchangeable. Here can we replace 'fusion' in the place of 'fission'? Not.

Can we reject D on the basis that the clause after as is in passive construction so it can't be parallel to clause before as
Is there anything wrong in my reasoning or can we have them as parallel

If you want to go by parallelism, then there must be a parallelism marker such as one of the fanboys. Here 'as' is only a comparison marker.

But generally, it is true that active and passive voice combinations are not favored combis when compared to same voice combis.

the key point is to realize that merging is not separate from power. this is hard point. we use our common sense of this world to realize this meaning point . we do need to understand a little bit of physics to realize this meaning point. we need a good general knowledge to solve this point.

in many questions, gmat challenge us to realize wheather two actions, one represented by a verb with tense, other represented by doing, are not separate. this point is basic and hard. whenever we see doing, ask ourself, wether the two actions are not separate.
