PREP SC Question

[John.D.]

Thirteen states from all regions of the country announced a plan to impose new controls on pollution from truck and bus engines in that they will jointly adopt eission limits that would be far stricter than the federal rules.
A to impose new controls on pollution from truck and bus engines in that they will jointly adopt
B to impose new controls on truck and bus engines' pollution by the joint adoption of
C to impose new controls on pollution from truck and bus engines, and jointly adopting
D for imposing new ontrols on pollusion from truck and bus engines, and jointly adopting
E for imposing new controls on truck and bus engine pollution in the joint adoption of

I eliminated BDE quickly, but really got confused while facing the choice between A and C.
I thought they have differnt meanings so I went for A. Do "in that they will jointly adopt" in A and "by jointly adopting" in C have the same meaning?
The "they" in A might be obscure, but I got a sentence, which I thought was where this question come from, from the New York Times:

Thirteen states from all regions of the country will try to impose new national controls on pollution from truck and bus engines on Monday, when they announce a plan to jointly adopt emission limits that would be far stricter than the federal rules.

There was a "they" there. Was it a bad usage that lead to obscure indication?

Thanx

[Testmania]

I can't differ them either!
Could anyone give me an explaination?

[RonPurewal]

what is the OA?

also, are you sure all the answer choices have been transcribed correctly? i don't terribly like any of them.

Following is the correct question from GMAT PREP

Thirteen states from all regions of the country announced a plan to impose new controls on pollution from truck and bus engines in that they will jointly adopt emission limits that would be far stricter than the federal rules.

(A) to impose new controls on pollution from truck and bus engines in that they will jointly adopt
(B) to impose new controls on truck and bus engines' pollution by the joint adoption of
(C) to impose new controls on pollution from truck and bus engines by jointly adopting
(D) for imposing new controls on pollution from truck and bus engines, and jointly adopting
(E) for imposing new controls on truck and bus engine pollution in the joint adoption of

O.A is C.........WHY C is better than B.
In my opinion "the joint adoption of" is incorrect in the context. It should be
"by jointly adopting" ?
First one is noun clause or gerund and second one is verb clause.

In B "verbing " is missing after " by"

Similar example:
Party won by wooing votors .......> correct
Party won by votors.........> incorrect

[anoo.anand]

can any one please explain why is D wrong ?

imposing and adopting look parallel ...

[sunny.jain]

thank GOD OA is C....

Initial Question literally shaked my concept...I was so confuse and finally i have to choose B...
now it should be C.

why I eliminated B:
trucks and cars engines' pollution : It awkward...

trucks and cars engines' pollution == > Pollution of trucks and cars engines

Good way :
Pollution from truck and bus engines

I first read by one Manhattan staff said , Try to use possessive form only for living entity.

Option A) - they is ambiguous
Option B) - Wrong expression
Option C) - Correct
Option D) - Wrong idiom : plan..for should be 'plan..to'
and
, and --> means they announced plan for jointly adopting emission limit
Option E) - wrong Idiom

[Ben Ku]

(B) has problems in several areas:
(1) "on truck and bus engines' pollution" is not preferred by the GMAT because it piles on multiple modifiers on top of each other: "truck and bus" modifies "engines" and "engines'" modifies "pollution." For clarity's sake, the construction in (C) "on pollution from truck and bus engines" is better. Also, the plural possessive ("engines' pollution") is not preferred by the GMAT because it is often unclear.
(2) "jointly adopting" is preferred over "the joint adoption" because verbs are stronger and usually more concise than action nouns.

Hope that helps.

[Ben Ku]

can any one please explain why is D wrong ?

imposing and adopting look parallel ...

Although (D) looks parallel, it actually isn't. To be parallel, the "for" should be carried over to the second part of the sentence.

Even still, "Thirteen states announced a plan for imposing new controls" and "for jointly adopting emission limits." structurally means that this plan had two equal parts: they are planning to impose new controls, and they are planning to jointly adopt emission limits."

However, this is not the meaning of the sentence. The purpose of the sentence is to explain that the way they will impose these controls is by adopting emission levels.

Hope that makes sense.

[tomslawsky]

D is wrong because of the word "and"

[sandeep.19+man]

In option A

1. Doesn't they refer to subject pronoun 13 states

2. Isnt the use of "in that" correct here?

So then what exactly is wrong with A? Is it just that C is better?
