IMO D

(A) Baltic Sea sediments, which are consistent with the growth of industrial activity there

which refers to sediments. The sediments cannot be consistent with the growth of industrial activity. out

(B) Baltic Sea sediments, where the growth of industrial activity is consistent with these findings

where refers to sediments which are not a place. out

(C) Baltic Sea sediments, findings consistent with its growth of industrial activity
its has no clear antecedent, perhaps Baltic Sea? can a sea have growth of industrial activity? out

(D) sediments from the Baltic Sea, findings consistent with the growth of industrial activity in the area
correct

(E) sediments from the Baltic Sea, consistent with the growth of industrial activity there
consistent seems to modify the previous clause. In addition there has no clear reference. It can refer to Baltic Sea but as It's already been said the sea has not growth of industrial activity.

A B C wrong because Baltic Sea sediments is incorrect. it has to be sediments from Baltic sea

Amongst D and E, D removes ambiguity of consistency by specifying findings

Baltic sea sediments is a wrong usage.It should be sediments from Baltic sea..

similar examples-I talked to the Indian soldier(Too Short)
I talked to the soldier from India(Better)

ural mountain ore ore from the ural mountain
Aegean sea salt salt from Aegean sea

Ergo A,B,C is not correct.

so now it is between D and E.
E is wrong because of "there"

Ergo D is the answer..

D.

I am not sure if there's anything wrong with saying Baltic sea sediments.

I eliminated A, B, C and E for other reasons.

A. which (x)
b. where (x)
c. its (x)
E. consistent....... (x)

Here's the SC question from GMAT Verbal review


38. Scientists have observed large concentrations of
heavy-metal deposits in the upper twenty centimeters of Baltic Sea sediments, which are consistent with the growth of industrial activity there.
(A) Baltic Sea sediments, which are consistent with the growth of industrial activity there
(B) Baltic Sea sediments, where the growth of industrial activity is consistent with these findings
(C) Baltic Sea sediments, findings consistent with its growth of industrial activity
(D) sediments from the Baltic Sea, findings consistent with the growth of industrial activity in the area
(E) sediments from the Baltic Sea, consistent with the growth of industrial activity there

My question is that how come findings seems to modify researche's obeservations?

Is that because -ing modifiers are more flexible and can refer to nouns that are not directly touching them?

"+ing" modifiers modify the subject of the preceding clause. So the subject in the first clause is the observations, so "findings" refers to those observations

Thanx, But there is one thing here I want to know about:

"Baltic Sea sediments" VS "sediments from the Baltic Sea"

The second one is redundant where we have the first one in Answer Choices. am I right?

Scientists have observed large concentrations of heavy-metal deposits in the upper twenty centimeters of Baltic Sea sediments, which are consistent with the growth of industrial activity there.

(A) Baltic Sea sediments, which are consistent with the growth of industrial activity there
First, I disagree with some previous posters. I believe the prepositional phrases should be disregarded and which refers to concentrations.

**EDIT (Oct 13, 2012): using are after which refers the reader to the most recent plural noun (sediments). In my original comment, I misspoke. The way the sentence is originally stated (and in option choice A), which are refers to sediments, but this isn't logical and it's understood that it wasn't the author's intent. The author intends to refer to the scientists' observation, which commands a singular verb (in other words, we need which is). Note that although the scientists observed concentrations (plural), their observation (singular) is what the relative clause beginning with which refers to.**

The phrase which are consistent with the growth doesn't match large concentrations. Growth cannot be consistent with concentrations (nor can it be consistent with sediments, centimeters, or deposits, for that matter). Also, Baltic Sea sediments isn't perfectly clear because Baltic Sea is a noun, not an adjective. In conversational speech, we often use nouns as adjectives, but it's not proper.

(B) Baltic Sea sediments, where the growth of industrial activity is consistent with these findings
Baltic Sea sediments is not a place, so where has no application here. Also, the ending is awkwardly worded. Findings are consistent with facts, not the other way around. Again, Baltic Sea sediments is improper.

(C) Baltic Sea sediments, findings consistent with its growth of industrial activity
its has no logical referent. Again, Baltic Sea sediments is improper.

(D) sediments from the Baltic Sea, findings consistent with the growth of industrial activity in the area
This sounds all right.

(E) sediments from the Baltic Sea, consistent with the growth of industrial activity there
Scientists observing concentrations can't be consistent with growth.

In answer D. may you explain why "findings",a noun, can go together with "consistent", an adj, without "be". Thanks

This is a good modifier question: You may view video solution below. This contains detailed explanation of why original choice is wrong and why other incorrect choices are incorrect.

You ask a very good question about the correct answer choice. It is a very good practice to thoroughly review the structure of the correct answer choice. The correct answer choice in this case utilizes a modifier that is called as Noun + Noun Modifier. Here "findings" is the noun part and "consistent with..." is the noun modifier of this noun. I suggest you review the article here for more details on this modifier. It would present a lot more clarity.

Hope this helps.

Regards,

Payal

Findings is noun; here it indicate the observation. So the options are C and D, boh have 'findings', but the option C has pronoun 'its' wrongly indicating the ancient findings, rather than sediments. So right answer D.

Hmm, I selected E, but seems C is the correct choice. However the sentence sounds very strange to me.
For me, findings is the plural of the noun finding. From pure reading I cannot understand that it refers to the observation...

In option E; consistent wrongly indicate Baltic sea; hence wrong

This is one of those booby traps that the GMAT folks try to trick you on.

The general rule is that an -ING verb positioned there modifies the subject.

But do we have an -ING verb?

Initially, it might LOOK like an -ING verb---but actually it's used as a NOUN.

The key is to notice the 's' at the end of FINDINGS. This tells us that we are dealing with a noun here.

Also, if you flip it - it doesn't make sense:

"Findings consistent with the growth of X, scientists have observed..." - it does not make sense for the descriptive phrase to modify the subject SCIENTISTS. Therefore, we know this is not the -ING verb that modifies the subject.

So keep in mind - look out for -ING verbs as possible descriptive phrases modifying the subject - but also be wary of booby traps--cases in which the -ING word is NOT used as a descriptive phrase. In this case, it's used as a noun that further describes what the scientists have observed.

Scientists have observed large concentrations of heavy-metal deposits in the upper twenty centimeters of Baltic Sea sediments, which are consistent with the growth of industrial activity there.
(A) Baltic Sea sediments, which are consistent with the growth of industrial activity there
(B) Baltic Sea sediments, where the growth of industrial activity is consistent with these findings
(C) Baltic Sea sediments, findings consistent with its growth of industrial activity
(D) sediments from the Baltic Sea, findings consistent with the growth of industrial activity in the area
(E) sediments from the Baltic Sea, consistent with the growth of industrial activity there

Hey everyone, the OA is D, which clearly does not have any issues. My question is about E. How do we know that "consistent with the growth of industrial activity there" modifies something inaccurately? Essentially, I can't seem to identify why this modifier can't modify Baltic Sea or if it does in the first place!. Some responses about this question have said it modifies the scientists observations, but using the noun modifier touch rule, that seems implausible.

Is there a way to systematically ascertain what a modifier modifies when it is at the end of a sentence? When modifiers are at the beginning of the sentence it is much easier to see what they modify, I wonder if there is a way to do that here. Thank you!!
I'm taking the gmat tomorrow, so I probably should know this by now....

Hi,

IMO in the option "E" the phrase consistent with the growth of industrial activity there is modifying Scientists..
Hence eliminate this option.

Option B : Where refers to Baltic Sea Sediments which is incorrect. Growth didn't happen in Sediments
Option C : Its does not have an antecedent.
Option D : Perfect
Option E : the phrase consistent with the growth of industrial activity there is modifying Scientists..
