Since 1992, in an attempt to build up the Atlantic salmon population

Dear Friends,

Here is a detailed explanation to this question-

Meaning is crucial to solving this problem:
Understanding the intended meaning is key to solving this question; the intended meaning of the crucial part of this sentence is that state officials in Maine have stocked each of the seven rivers in which salmon still spawn with fry raised in hatcheries from eggs produced by wild fish found in that particular river.

Concepts tested here: Meaning + Pronouns

A: This answer choice incorrectly uses the plural pronoun "them" to refer to the singular pronoun phrase "that particular river".

B: This answer choice alters the meaning of the sentence through the phrase "the river"; the use of this phrase incorrectly implies that state officials in Maine have stocked one particular river with fry raised in hatcheries from eggs produced by wild fish found in that particular river; the intended meaning is that state officials in Maine have stocked each of the seven rivers in which salmon still spawn with fry raised in hatcheries from eggs produced by wild fish found in that particular river.

C: The sentence formed by this answer choice suffers from pronoun ambiguity, as the pronoun phrase "that particular river" lacks a clear and logical referent.

D: Correct. This answer choice uses the phrase "each river", conveying the intended meaning - that each of the seven rivers in which salmon still spawn with fry raised in hatcheries from eggs produced by wild fish found in that particular river. Further, the sentence formed by Option D correctly provides a clear and logical referent - the singular pronoun phrase "each river" - for the singular pronoun phrase "that particular river".

E: This answer choice alters the meaning of the sentence through the phrase "that river"; the use of this phrase incorrectly implies that state officials in Maine have stocked one particular river with fry raised in hatcheries from eggs produced by wild fish found in that particular river; the intended meaning is that state officials in Maine have stocked each of the seven rivers in which salmon still spawn with fry raised in hatcheries from eggs produced by wild fish found in that particular river.

Hence, D is the best answer choice.

All the best!

C - them is not clear. "the rivers" makes it clear

we are talking about seven rivers so "the rivers" makes sense.
I will go with option C.

Answer D.

Since 1992, in an attempt to build up the Atlantic salmon population in each of the seven rivers in which salmon still spawn, state officials in Maine have stocked each river with fry raised in hatcheries from eggs produced by wild fish found in that particular river.


Thanks,

I will go with D, "in that particular river." gave me the way.

At first I have also thought about option C , but later 've seen " in each of the seven rivers " is the notion of the potential answer for being the OA " each river " .

Cant understand why D is right over C ? and how 'in that particular river' made us to use 'each river'?
Can you please elaborate the reasoning ?

Thanks & Regards

This is purely a meaning based question. hope you understand 'them' can't be used , as it made pronoun error. Now point it that there are many type of salmon. and each river has their own type of salmon. Each river has been stocked with the salmon that is already there. "particular river" is a singular term and it demands singular subject. Only D made any sense here. Hope it helped.

End of the sentence non underlined portion "that particular river" is the hint for this question. Which means.sentence is talking about each river

Thanks Now i understand properly....there are many type of salmon. and each river has their own type of salmon. Each river has been stocked with that type of salmon

Since 1992, in an attempt to build up the Atlantic salmon population in each of the seven rivers in which salmon still spawn, state officials in Maine have stocked them with fry raised in hatcheries from eggs produced by wild fish found in that particular river.

(A) them
(B) the river
(C) the rivers
(D) each river
(E) that river

(D) because - state officials in Maine have stocked them with fry raised in hatcheries from eggs produced by wild fish found in that particular river.

Each river - that particular river, both are in same number

Straight Option D in the end of the sentence particular river is used which is singular hence "Each river" makes sense
Them is incorrect as no pronoun referent

Since 1992, in an attempt to build up the Atlantic salmon population in each of the seven rivers in which salmon still spawn, state officials in Maine have stocked them with fry raised in hatcheries from eggs produced by wild fish found in that particular river.

(A) them
(B) the river
(C) the rivers
(D) each river
(E) that river



How the green part describes the wrong answer C? In the green part the pronoun ''her'' may be used for both Jane and Sharon. So, the use of pronoun (her) for both Jane and Sharon is wrong assuming that both Jane and Sharon are female. But, C says ''Since 1992, in an attempt to build up the Atlantic salmon population in each of the seven rivers in which salmon still spawn, state officials in Maine have stocked the rivers with fry raised in hatcheries from eggs produced by wild fish found in that particular river.
In this official wrong sentence, there is NO use of one single pronoun (like ''her'' in your green part), which indicates 2 different NOUNs. So, I'm still NOT sure Why did you correlate your green part with this official wrong answer (C)? Can you clarify a bit, Ron?

Also, if I say:
Jane was talking to Sharon about her children
^^ is this sentence legitimate in GMAT if someone think that Sharon is female and Jane is Male?
Also, is the following sentence is legitimate in GMAT?

Since 1992, in an attempt to build up the Atlantic salmon population in each of the seven rivers in which salmon still spawn, state officials in Maine have stocked them with fry raised in hatcheries from eggs produced by wild fish found in that particular river.

(A) them - ambiguous - stocked what? rivers or the salmon
(B) the river - not a single river
(C) the rivers - not specific how many
(D) each river - correctly defines that each river is stocked
(E) that river - not one but 7 rivers

C is not correct because " the rivers" does not work with "that particular river." For C to work, the last part of the sentence would have to read "those particular rivers."

Since 1992, in an attempt to build up the Atlantic salmon population in each of the seven rivers in which salmon still spawn, state officials in Maine have stocked them with fry raised in hatcheries from eggs produced by wild fish found in that particular river.

(A) them - ambiguous - Referring to the officials or to the rivers?
(B) the river - We are discussing a group of rivers, not one.
(C) the rivers - This is trickier than it seems, but I believe the reason this is wrong is because it is ambiguous whether we are still discussing the same rivers, some other group of rivers, or even ALL rivers .
(D) each river - Correct and is nicely parallel with the earlier "Each of the seven rivers"
(E) that river - We are discussing a group of rivers, not one.

I'm mainly adding to the discussion because I also chose C and was not satisfied with the explanations given thus far. If an expert could chime in it would be wonderful.
