Not only did the systematic clearing of forests

[netigen]

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 caused erosion and very quickly deforested whole regions.

Is it B?

In B what is "Which" modifying?

The GMAT loves to test the "not only... but also" construction. Whenever half of this construction appears, the other half will as well.

So, we can quickly eliminate (c), (d) and (e).

(a) has a verb tense problem: "create... and gave..." are not parallel, yet they should be. i.e., the sentence should read "create...and give...".

To be honest, I'm not a huge fan of (b) either. For the sentence to be truly parallel, there should be an "it" after the comma.

A better version would have been:

"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 also"

Also, if (e) ended with "but also" instead of "but it", it would be perfect.

What's the source of this question?

[netigen]

Thanks Stuart appreciate the clarification

[nishchal]

I agree with Stuart. b,d and e are out because of incorrect idiom. E would have been the best choice if it ended with "but also".

In (b) it should be "created" to go with "gave" to be a better answer.

I picked (b) over (a) just because adding ",which gave" seems to be a better modifier for first part of sentence rather than "and gave" and also because it used "but also" instead "but it also".

Pick (b) but not 100% sure.

Can you please post the answer and the source of question. Wonder if there was a typing mistake in question/answer?

[chidcguy]

Jeez, I picked E and read it as if "it" were in there.

Thats a creepy Q Also, When I read B I marked it wrong as it should have been either created and gave or create and give.

A) construction not parallel (Gave)
B) changes the meaning of the sentence, the farmland did not give consumers cheaper houses and furniture
C) Not clear with the Not Only... But also
D) verb construction is parallel, but not only... but also is missing. For me, this is the best answer still, as it does not change the meaning of the original sentence. This raises the question: If A also cause B, do we have to begin the sentence with a "Not only"? I'm not sure.
E) As in B, this changes the meaning of the sentence. The creation of farmland does not give consumers cheap houses. That makes no sense.

[s_raizada]

Is split 'but also' such as 'but it also' correct usage?

I thought split 'not only' and 'but also' are never correct!

[netigen]

I think splits are allowed in general. I have seen cases where "such as" is split for e.g. "such positions as"

------------------------------------------------------------------------
A eliminated because incorrect use of tense
C Not clear/ incorrect sentence formation/wrong use of tense
E "Also" missing in the end.

Between B and D my take is as follows:

"B" wud have been correct theoretically, because it uses the constuction/idiom "Not only .... but also".
However, B changes the meaning of the sentence, by incorrectly placing "which"

Secondly, "Not only .... but also" construction is used while comparing 2 or more positive qualities and when we want to emphasize on the 2nd quality. For ex:

Not only is Radha talented but also extremely beautiful.

Now consider this 2nd example:

Not only is Radha talented but also extemely notorious.

Thus when contrasting a good quality/aspect with a bad quality/aspect, the use of "Not only .... but also" looks inappropriate.

Ideally, the use of "....But also..." alone wud be more apt.
Radha is beautiful and talented..... but also very naughty.

In the original sentence.... The systematic clearing of forests in US gave inexpensive houses (+ve) and inexpensive furniture (+ve), but it also caused erosion of land (-ve)

So "D" wud actually read as:

THOUGH 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

Hence I wud go with "D" because it clearly draws the meaning of the sentence while explicitly stating the positive and negative outcomes of the act of clearing forests in US.

wats the OA

[schumi_gmat]

Isn't, Not only X.....but (also) Y correct usage?

[Bidisha800]

Isn't, Not only X.....but (also) Y correct usage?

Yes, it is correct

[schumi_gmat]

In E it is the construction "Not only....But" which is correct then why is E wrong
