So sneaky of them!

The test writers know that many students who do their homework will see the "not only" trigger and look for a "but also" bookend. If you have the first half of that construction, you should probably have the second. *But* the sneaky twist is that if you have the second half ("but also") you don't necessarily need the first ("not only").

Ex:
She likes not only shaggy puppies, but also short-haired ones. *CORRECT*

He studies a lot, but he also likes to have fun.
*STILL CORRECT*

Great catch mari and daryayurlova on the lack of verb parallelism in two different places in this sentence. "Not only"/"but also" is indeed a parallelism marker, so that knocks off (A) ("create"/"gave" are not in parallel tenses), (B) ("caused" is missing a subject so that clause is not parallel to the first part), and (E) ("created"/"it caused" are not parallel).

That leaves (C) and (D), neither of which contain "not only"-- both choices use "but also" to mean X BUT (also/additionally) Y, which is a perfectly valid usage, though less emphasized in most GMAT curricula.

"But" is still a parallelism marker. Break down C and D to their underlying skeletons:

(C) contains a modifier between those two commas ("creating farmland.furniture), so the core of (C) is really "The clearing, but also..." So what should follow to maintain parallelism? Another noun or noun phrase-- instead we have a verb ("caused")-- the core of (C) would read "the clearing but also caused erosion..."-- that doesn't make any sense! Eliminate.

Try the same thing for (D):
The clearing...created farmland...and gave (stuff)..., but it (the clearing!) also caused erosion.

The underlying structure is
subject verb and verb, but subject also verb.

Parallel and correct!

I read it on a forum somewhere..

Not only... But also ... is basically used when both the clauses have the same note i.e. either positive or negative..

Eg: Not only did he score well, but also he topped the exams.

However, in the above sentence, both the clauses are contrasting in the mood.. thus, D choice fits the mood perfectly..

The ans looks like D.What is the OA?

not only A....but also B should be used when both A and B are presented in a positive manner or negative manner.
Since it is a mix of both in this case you have to show contrast using 'but'

It should be between D and E

A. Not only did the systematic clearing of forests in the United States create farmland (especially in the Northeast) and gave consumers relatively inexpensive houses and furniture, but it also -Incorrect, gave should be give

B. Not only did the systematic clearing of forests in the United States create farmland (especially in the Northeast), which gave consumers relatively inexpensive houses and furniture, but also - I would prefer a present participle form "giving" instead of "which gave"

C. The systematic clearing of forests in the United States, creating farmland (especially in the Northeast) and giving consumers relatively inexpensive houses and furniture, but also -Introducing sentence fragmentation.

D. The systematic clearing of forests in the United States created farmland (especially in the Northeast) and gave consumers relatively inexpensive houses and furniture, but it also

E. The systematic clearing of forests in the United States not only created farmland (especially in the Northeast), giving consumers relatively inexpensive houses and furniture, but it

Out of D, E

It is D

Logically the 2 parts are showing a contrast, on one hand, clearing of forests was beneficial, but it was harmful on the other. D brings out this contrast well with a single "but"

Not only X but also Y is used to present 2 similar effects, for eg: not only did X create farmland, but it also gave inexpensive furniture.

E too has the not only..But.. construction. so its wrong

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

D for me.

The sentence is saying that 'systematic clearing of forests' had couple good effect but it had couple bad effects also.

good effects --> created farmland and gave inexpensive furniture and houses

But

bad effects --> caused erosion and deforested whole regions.

D. The systematic clearing of forests in the United States created farmland and gave consumers relatively inexpensive houses and furniture, but it also caused erosion and deforested whole regions.

Not only DID the systematic clearing of forests CREATE farmland ..
and GIVE/GAVE consumers

GAVE is not correct ... did + 2nd form

'not only .. but also' construction is used for items that are logically parallel.
the first half of the sentence is positive (create/give) while the second half is negative (erosion/deforested) .. so the use of this construction is not appropriate

D is the correct ans. HTH

I'd argue both are still similar elements, because they are both the effects of clearing forests. Similar = having common properties, but different.

I've not heard of the similar rule for NOT ONLY....BUT ALSO rule. Can you elaborate?

NOT ONLY... BUT ALSO sentences are typically used to talk about two different things which run in parallel. In this case, I'd agree with Ashish above and note that farmland = good, erosion = bad; they might both result from the clearing of forests, but they don't run in parallel directions, and should therefore not be spliced together with a NOT ONLY... BUT ALSO conjunction.

It should be D

Not only , but also is used with two things that a parallel.

Here one is giving a positive effect and the second a negative , and hence this usage is not suitable.
Here it is illogical to use "not only, but also"

So A and B out
C is a fragment - Out
E - "giving consumers relatively inexpensive houses and furniture" - this is modifying the previous clause, which again is illogical - Out.

Thanks,
Ankit

Here's the first look in what I wanted to test for: proper idiom (not only, but also), grammatical construction (complete sentence), misplaced modifier (gave/giving)

A. Not only did the systematic clearing of forest in the United States create farmland (especially in the Northeast) and gave consumers relatively inexpensive house and furniture, but it also Wrong - "create" should be past tense and parallel to "gave"; "but it also" is a red flag, but it seems grammatically correct.

B. Not only did the systematic clearing of forest in the United States create farmland (especially in the Northeast), which gave consumers relatively inexpensive houses and furniture, but also Wrong - "which gave" improperly modifies farmland; there should be no comma before "but also" because it shares the same subject.

C. The systematic clearing of forests in the United States, creating farmland (especially in the Northeast) and giving consumers relatively inexpensive houses and furniture, but also Wrong - The subject "the systematic" needs a verb; "but also" lacks a subject too.

D. The systematic clearing of forests in the United States created farmland (especially in the Northeast) and gave consumers relatively inexpensive houses and furniture, but it also Correct - "It" takes the "systematic clearing"; the verbs are parallel.

E. The systematic clearing of forests in the United States not only created farmland (especially in the Northeast), giving consumers relatively inexpensive houses and furniture, but it Wrong - lacks correct idiomatic expression (not only...but also); "it" doesn't have a proper referent, as the subject should already be implied

I eliminated A and B for the reason mentioned above. I need to know whether my reasoning is correct or not.

(b) Not only did the systematic clearing of forests in the United States create farmland (especially in the Northeast), which gave consumers relatively inexpensive houses and furniture, but also

I eliminated A and B for the reason mentioned above. I need to know whether my reasoning is correct or not.

First note that not only..but also is a conjunction, a correlative conjunction.

Now option A: There are 2 independent clauses in this sentence as shown below (the verb error in the first clause is corrected):

Independent clause 1: The systematic clearing of forests in the United States did create farmland (especially in the Northeast) and give consumers relatively inexpensive houses and furniture.
Independent clause 2: It caused erosion and very quickly deforested whole regions.

These 2 independent clauses are joined by a correlative conjunction not only.. but also.

Now option B: There are 2 independent clauses in this sentence too as shown below (The modifier error in the first clause and the subject error in the second clause are corrected):

Independent clause 1: The systematic clearing of forests in the United States did create farmland (especially in the Northeast), giving consumers relatively inexpensive houses and furniture.
Independent clause 2: It caused erosion and very quickly deforested whole regions.

Again these 2 independent clauses are joined by a correlative conjunction not only.. but also.

Therefore one cannot eliminate option A and option B on the ground that there is no independent clause. In each sentence there are 2 independent clauses joined by a correlative conjunction.

A. Not only did the systematic clearing of forest in the United States create farmland (especially in the Northeast) and gave consumers relatively inexpensive house and furniture, but it also

E. The systematic clearing of forests in the United States not only created farmland (especially in the Northeast), giving consumers relatively inexpensive houses and furniture, but it

D for me
Lets first concentrate on the meaning of the sentence..then we will look at the options...

Meaning: THE ACT OF The systematic clearing of forest(this is a noun phrase referring to the event as a whole) both created the farmland and gave the consumers the inexpensive furniture, but this act was also responsible for the erosion and deforestation.

Now lets consider each option...

A. Not only did the systematic clearing of forest in the United States create farmland (especially in the Northeast) and[Parallel marker] gave(The two Italicized verbs must be parallel, in other words, gave must be give) consumers relatively inexpensive house and furniture, but it also(must be but also)
Eliminated

B. Not only did the systematic clearing of forest in the United States create farmland (especially in the Northeast), which gave consumers(Wrong..the farmland did not give the furniture and houses to the consumers) relatively inexpensive houses and furniture, but also
Eliminated

C. The systematic clearing of forests in the United States, creating farmland (especially in the Northeast) and giving consumers relatively inexpensive houses and furniture, but also
Italicized words not parallel to "caused"
Eliminated

E. The systematic clearing of forests in the United States not only created farmland (especially in the Northeast), giving consumers relatively inexpensive houses and furniture(The creation of farmalnd did not result in consumers getting inexpensive furniture), but it(must be BUT ALSO)
Eliminated

Leaves us with D..strengthening this option..let analyze this

D. The systematic clearing of forests in the United States created farmland (especially in the Northeast) and gave consumers relatively inexpensive houses and furniture(Independent Clause), (Dependent Clause)but it(this is the subject of this clause) also(There can be a but it also)--caused(present in the question)

Both the clauses are parallel, as their verbs are parallel, and but it also introduces a dependent clause. The two clauses are also connected properly[Independent Clause + , + but(subordinating conjunction) it also...whole regions(Dependent Clause)]. This also clearly reflects the intended meaning.

Without "not only", "also" is not mandatory. However it is not wrong to use it - it is then used independently, not as a part of a conjunction.

In option b, did is parallel to caused, so why can't we have 'b' as our answer?
