By pressing a tiny amount of nitrogen between two diamonds to a pressure of 25 million pounds per square inch, scientists not only were able to transform the gas into a solid, but they also created a semiconductor similar to silicon.

(A) not only were able to transform the gas into a solid, but they also created
(B) not only were able to transform the gas into a solid but also creating
(C) were able not only to transform the gas into a solid but to create
(D) were able not only to transform the gas into a solid but also creating
(E) were not only able to transform the gas into a solid, but they were also able to create

OA IS C.
However, that is not the idiom not only but also.

Hi,

It is true that we generally use “not only” pairing it with “but also” to denote two aspects of the same thing. However, the use of “not only… but…” is not incorrect (but that we encounter in rare occasions).

We use “not only A but also Y” or “not only X but Y”, what we must pay attention to is that the entities following both the markers (X and Y) must be logically as well as grammatically parallel.

In this sentence, only choice C adheres to this rule of parallelism: were able not only to transform the gas into a solid but to create. The entities that follow both the markers are grammatically (to verb-forms) as well as logically parallel. Hence choice C is correct.

Hope this helps.

Please clarify.



Correct idiom is "Not only X ... but also Y", where X and Y both has to be parallel. In the options A, B, D and E, these are not parallel.

Only option C seems correct.

In Manhattan SC book, check out the page no. 161 of 4th ed. "Not only X ... but Y" is given under SUSPECT idiom, i.e. this can be used sometimes.

Other examples given are

1. We wore NOT ONLY boots BUT sandals.
2. We wore NOT ONLY boots BUT sandals AS WELL.

See in both the options "boots" (X) are parallel to "sandals" (Y)

'not only ... but also' in generally preferred, but gmatprep has featured at least one problem featuring 'not only ... but' in the correct answer

the correct answer is c, the only choice that features proper parallelism. it omits the word 'also', but it's still correct.

Thanks for your reply.

I have also seen NOT ONLY....BUT THEY ALSO.... in some other correct question.
What do you think about that?

Not only x but also y is a correlative conjunction. A correlative conjunction joins two equal elements. In the sentence above, the elements, to transform the gas and created a semiconductor, are not equal hence the reason "not only but also" is not correct.

According to whatever little bit knowledge I have, I don't think NOT ONLY... BUT THEY ALSO can be correct. What I have read is correct idiom should be NOT ONLY X .... BUT ALSO Y, where X and Y should be parallel. Can you provide some examples or source?

Hey noboru,

In my opinion its not correct; May be the sentence you encountered is using "NOT ONLY....BUT THEY ALSO" in some context.

But its not the correct idiom.

Thanks

According to my understanding, the following construcions are...

NOT ONLY X BUT ALSO Y: CORRECT
NOT ONLY X BUT IT/THEY ALSO Y: INCORRECT
NOT ONLY X BUT Y: CORRECT
X, BUT Y: CORRECT
X, BUT ALSO Y: CORRECT

If I go with idiom (Not only ... but also): then I'm goona choose B.

But, some how D looks good to me as compared to B.

C. were able not only to transform the gas into a solid but to create parallel!
D. were able not only to transform the gas into a solid but also creating not parallel

I would have chosen "D" first, but i noticed that "creating" is not parallel to "transform", so that only "C" is correct. Even though it is "not only X" .. "but Y" without also. Thanks for the questions and explanation

Got to say good question went for E but realized on close inspection C is right. This construction is something you don't see very often

Not only X but Y

There is a way to check in not only X but also Y or not only X but Y construction whether selected choice is correct.

<Modifier>....., scientists not only were able to transform the gas into a solid, but they also created a semiconductor similar to
silicon.

So, scientists were able to do two things which should stand independently by themselves.

A. not only were able to transform the gas into a solid, but they also created
B. not only were able to transform the gas into a solid but also creating
C. were able not only to transform the gas into a solid but to create
D. were able not only to transform the gas into a solid but also creating
E. were not only able to transform the gas into a solid, but they were also able to create

Choice C:
Scientists were able not only to transform the gas into a solid.
Scientists were able but to create a semiconductor similar to silicon.

Both are independent sentences that can stand by their own.This method has helped me quickly eliminate choices in this type of construction.Like in this sentence, choices B & D can be eliminated easily. Hope it helps you too!

In what way is parallelism missing in E?

The option says "the scientists were not only able to transform..., but also able to create..." which seems parallel to me (or am I missing something?)


Thanks in advance!

"Scientists were" is OUTSIDE the parallelism structure and hence covers both NOT ONLY.... and BUT ALSO.....

Thus using "they were" within the second element (BUT ALSO) is wrong. If "they were" is to be used within the second element (BUT ALSO), then "scientists were" should also be brought WITHIN the first element (NOT ONLY). Then the sentence would be:

..not only scientists were able to transform the gas into a solid, but they were also able to
create....

OK, let me try to explain a bit more elaborately. Consider this way:

Parallelism marker: NOT ONLY (X), BUT ALSO (Y).
X and Y should be parrallel.

Correct: Scientists were NOT ONLY ( able to transform), BUT ALSO ( able to create).
able to transform and able to create are parallel.

Correct: NOT ONLY (Scientists were able to transform), BUT ALSO ( they were able to create).
Scientists were able to transform and they were able to create are parallel.

Wrong: Scientists were NOT ONLY ( able to transform), BUT ALSO ( they were able to create).
able to transform and they were able to create are NOT parallel.

I stumbled upon a great explanation by "Ron". Sharing it for benefit of others

-----------------
There is really only one base structure here, which is "not ... but ..."

that's actually the only TRUE set of parallel markers here. "only" and "also" are adverbs, and so ultimately function as modifiers -- i.e., they aren't necessary to the structure.
Still, since "not only ... but also ..." is so common, you may want to memorize it separately -- but be aware that this is NOT the only correct form of this idiom.

The MOST reliable way to deconstruct this idiom is just to memorize "not ... but ...", and then ignore the adjectives "only" and "also" in deciding whether structures are grammatically parallel.
In deciding the MEANING of the structure, you can't dismiss "only" and "also" ... but that's a separate issue.

EXAMPLES: BE SURE YOU CAN UNDERSTAND WHY EACH OF THESE IS CORRECT OR INCORRECT

the writer was not only mortified by her mistake but determined to correct it in print.
--> CORRECT

the writer not only was mortified by her mistake but was determined to correct it in print.
--> CORRECT

the writer was not only mortified by her mistake but was determined to correct it in print.
--> INCORRECT

the small child was relieved to hear that the rustling under the bed was caused not by a ghost but by his pet cat.
--> CORRECT

the small child was relieved to hear that the rustling under the bed was caused not by a ghost but his pet cat.
--> INCORRECT

SO WHAT'S THE DIFFERENCE, THEN, WITH
"not only ... but also ..."
"not only ... but ..."
"not ... but ..."
?

The difference here is strictly one of MEANING.

The first two are pretty similar; the last one is TOTALLY different.

(1) "not only ... but also ..." is used to refer to two descriptions that REINFORCE each other (i.e., both have the same connotation -- two good things, two bad things, two helpful things, etc.), but are fundamentally independent.
ex:
this drug is not only an alertness aid, but also an antidepressant.
--> "alertness aid" and "antidepressant" are TWO GOOD THINGS that have basically NOTHING TO DO WITH EACH OTHER.
Therefore, "not only ... but also".

Wrong: The drug not only kills the bacteria but also kills white cells. (Doesn’t make sense as explained, one good, one bad -- so the context here is inappropriate)
[Correct Version can be written with just “but”: The drug kills the bacteria but also kills white cells.]

Correct: The drugs not only kills the bacteria but also alleviates joint pain. (Both effects described are positive)

(2) "not only ... but ..." is also used to refer to two descriptions that REINFORCE each other, but it's generally used when the second description EXPANDS or GOES BEYOND the first.
ex:
ryan not only competed in all the events, but won first prize in three of them.
--> Note that "won first prize in three of [the events]" is an EXTENSION of "compete[ing] in all the events". These are not independent.

The above difference between (1) and (2) is subtle, and is therefore not terribly important. However, you MUST be able to tell those from the next one:

(3) "not ... but ..." is used when the FIRST thing is EXPECTED, ASSUMED, or PREVIOUSLY THOUGHT, but is REFUTED / CONTRADICTED / DISPROVED by the SECOND thing.
ex:
the snacks known as "French fries" were invented not in France, but in Belgium.
--> The initial assumption, which is refuted, is that French fries are from France.

--> I was surprised to learn that Ella was not Clint's biological daughter but in fact his adopted daughter, since her facial features so closely resemble his.
(Here, since the girl looks so much like her dad, we EXPECT to find out that she's his biological daughter.)

[Other scenarios:

"not only....also..."

 This could work, if there were some other transition signal (e.g. a semicolon) to replace the missing "but".
For instance:
The Acme Battery Corporation does not only make batteries; it also makes battery accessories, such as chargers.

In this case, the meaning is largely the same as that of "not only ... but also..."

"not only ... also" doesn't make grammatical sense; the inclusion of the conjunction "but" is of the utmost importance. If you don't have this conjunction, then the sentence thus created becomes a run-on

"not....but also..."
 Doesn't seem logical under any circumstances

"X but Y":
this just implies a contrast, but NOT any expectation.
e.g.,
I am not a mechanic, but can perform basic maintenance on non-hybrid cars.
]

--------------
Hope it can explain why C is correct
