School integration

[drgmatIL]

School integration plans that involve busing between suburban and central-city areas have contributed, according to a recent study, to significant increases in housing integration, which, in turn, reduces any future need for busing.
(A) significant increases in housing integration, which, in turn, reduces
(B) significant integration increases in housing, which, in turn, reduces
(C) increase housing integration significantly, which, in turn, reduces
(D) increase housing integration significantly, in turn reducing
(E) significantly increase housing integration, which, in turn, reduce

E is wrong because "reduce"
I thought that we need increase after to in order to prevent "broken" infinitive
Why C is wrong? Why A is correct?

[iamcste]

Adverb signficantly should modify the verb "increase" and not the subject "Housing integration"

This is reason why C is defintely not the answer.

A is correct bcoz "increases" now becomes the subject and "significant" is now an adjective and an adjective can modify noun

Plus reduces gives precise subject verb agreement "reduces"

Anybody , if there is a fallacy, in reasoning, kindly let me know

Which should refer to a non and not to a phrase.
In option C which is tryinh to modify the phrase" to increase housing integration significantly".

In option A which correctly modifies the noun integration.

if 'increases' (plural) is noun, should 'reduces' be 'reduce'?

Housing integration is singular hence reduces should be used.

[lamhe]

contribut to is the correct idiom....A is correct here

Let's rewrite each option once again:-

(A) School integration plans that involve busing between suburban and central-city areas have contributed to significant increases in housing integration, which, in turn, reduces any future need for busing.
No error, let's keep it.

(B) School integration plans that involve busing between suburban and central-city areas have contributed to significant integration increases in housing, which, in turn, reduces any future need for busing.
Significant increase in housing integration or significant integration? Meaning changed.

(C) School integration plans that involve busing between suburban and central-city areas have contributed to increase in housing integration significantly, which, in turn, reduces any future need for busing.
IN is missing

(D) School integration plans that involve busing between suburban and central-city areas have contributed to increase in housing integration significantly, in turn reducing any future need for busing.
IN is missing

(E) School integration plans that involve busing between suburban and central-city areas have contributed to significantly increase in housing integration, which, in turn, reduce any future need for busing.
IN is missing

if 'increases' (plural) is noun, should 'reduces' be 'reduce'?

Housing integration is singular hence reduces should be used.

Thanks for your response, but I am still not fully convinced :!:
I am still doubtful about what caused 'reduction in any future need for busing'; 'INCREASES in housing integration' or 'HOUSING INTEGRATION'.

Any inputs would be greatly appreciated.

(A) significant increases in housing integration, which, in turn, reduces
(B) significant integration increases in housing, which, in turn, reduces
(C) increase housing integration significantly, which, in turn, reduces
(D) increase housing integration significantly, in turn reducing
(E) significantly increase housing integration, which, in turn, reduce

E is wrong because "reduce"
I thought that we need increase after to in order to prevent "broken" infinitive
Why C is wrong? Why A is correct?

I think this whole question is about misplaced modifiers, modifiers that modify something you didn't intend them to modify.

B is incorrect because of misplaced modifier problem. "increases" should be just after significant.

C is also incorrect because of misplaced modifier problem. "Significantly" should be placed before increase.

D.. same issue as C.

[syflysun]

btw, two more questions:
where is the right place for a "adv" such as significantly here?

1>to increase sth. significantly
2>to significantly increase sth. [i do remember "to+adv+do" is an incorrect structure in some gmat sc book.]

what should follow "contribute to"

1> contribute to do
2> contribute to doing
3> contribute to n.

many thanks. let us discuss!!!

It again boils down to what does WHICH refer to? Considering context and meaning, it appears to me that both seem to be correct

- Increases in housing integration
- Housing integration

What does 'which' refer to here? Depending on this, verb (reduce vs reduces) need to be decided.

Any thoughts on the above?
