Dear Friends,

Here is a detailed explanation to this question-
GMAT TIGER
The agreement, the first to formally require industrialized countries to cut emissions of gases linked to global warming, is a formal protocol by which 38 industrialized countries must reduce emissions of these gases by 2012 or face heavy penalties.

(A) by which
(B) for which
(C) under which
(D) such that
(E) wherein


Meaning is crucial to solving this problem:
Understanding the intended meaning of this sentence is key to solving this question; the intended meaning of the crucial part of this sentence is that the agreement is a formal protocol that requires 38 industrialized countries to reduce emissions of certain gases by 2012 or face heavy penalties.

Concepts tested here: Meaning

A: This answer choice alters the meaning of the sentence through the phrase “by which”; the use of “by” incorrectly implies that the agreement is a formal protocol that 38 industrialized countries must use to reduce emissions of certain gases by 2012 or face heavy penalties; the intended meaning is that the agreement is a formal protocol that requires 38 industrialized countries to reduce emissions of certain gases by 2012 or face heavy penalties.

B: This answer choice alters the meaning of the sentence through the phrase “for which”; the use of “for” incorrectly implies that the agreement is a formal protocol on whose behalf 38 industrialized countries must reduce emissions of certain gases by 2012 or face heavy penalties; the intended meaning is that the agreement is a formal protocol that requires 38 industrialized countries to reduce emissions of certain gases by 2012 or face heavy penalties.

C: Correct. This answer choice uses the phrase “under which”, conveying the intended meaning – that the agreement is a formal protocol that requires 38 industrialized countries to reduce emissions of certain gases by 2012 or face heavy penalties.

D: This answer choice alters the meaning of the sentence through the phrase “such that”; the construction of this phrase incorrectly implies that the agreement is a formal protocol in such a manner that 38 industrialized countries must reduce emissions of certain gases by 2012 or face heavy penalties; the intended meaning is that the agreement is a formal protocol that requires 38 industrialized countries to reduce emissions of certain gases by 2012 or face heavy penalties.

E: This answer choice alters the meaning of the sentence through the preposition “wherein”; the use of “wherein” illogically implies that the agreement is a formal protocol, and inside this protocol 38 industrialized countries must reduce emissions of certain gases by 2012 or face heavy penalties; the intended meaning is that the agreement is a formal protocol that requires 38 industrialized countries to reduce emissions of certain gases by 2012 or face heavy penalties.

Hence, C is the best answer choice.

All the best!

weird one. Looks like an idiom test.
C sounds ok. "agreement is a protocol under which". I am not sure of the usage of wherein.

C/E. Would pick C since I am not sure of E.

a. by which
b. for which
c. under which
d. such that
e. wherein

C. It's a little ugly, but grammar comes first... protocols, agreements, contracts should be coupled with under

ConkergMat
I am not sure of the usage of wherein

1.wherein = in which

2. keep in mind that "protocol under which", so no matter whether it is "in, for or by which"

C is the best

a. by which - whatever follows by will tell you the process...so A is out
b. for which - changes the meaning of the sentence
c. under which - correct
d. such that - I guess such that and such as is used for list
e. wherein - changes the meaning.

IMO C
