Thank you!

What was your thought process, I'm curious.

There is another problem with E..

Before that in Option D "Findings (noun) consistent with the growth of industrial activity in the area (Noun modifier).

This construction correctly of "Noun+Noun modfier " modifies observations of the scientists

In option E, consistent with the growth of industrial activity there

is just a modifier phrase and is again modifying "observations", which is another noun in the sentence. In GMAT a noun modifier should be as close as possible to the noun modified where as a modifier modifying a verb need not be as close to the verb being modified.

Thus E is incorrect.

Before posting it is worthwhile to check if the questions have been discovered. GMATCLUB has been around for a long time and you can be rest assured that there will be a very very slim chance of a OG question not discussed on this site.

Use search option and save time.

The easiest way to eliminate B is that where is used to modify a place. Baltic Sea sediments is not a place; it is a thing (in lack of better word).

The way where is used in this sentence, it is a relative pronoun. The relative pronouns have many characteristics that are tested on GMAT. For example, the relative pronouns that and which cannot modify people and many other things.

p.s. These have been discussed in detail in our book. If you can PM me your mail id, I can send the corresponding section to you.

Fairly simple one.

A - 'which' refers to sediments. Sediments can not be consistent with growth of industrial activity
B - 'where' can not refer to 'sediments'
C - no antecedent for 'its'
D - IMO right! 'findings' rightly sums up the scientists observations
E - Not clear what is 'consistent with the growth of industrial activity there'.

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, whichare consistent with the growth of industrial activity there................... SV agreement error
(B) Baltic Sea sediments, where the growth of industrial activity is consistent with these findings........................................ Meaning changed " growth of industrial activity in the baltic sea sediments"
(C) Baltic Sea sediments, findings consistent withits growth of industrial activity.............................. "its" is creating ambiguity
(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[/quote] .................................... "there' is referring to baltic sea which is wrong.

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.

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

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

So that means in Correct Answer "D" the word "finding" is used as a Noun+modifier(absolute phrase) and not as a ing modifier. Correct me if I though tit right. I have not seen this construction before and wondering if it's possible.

And if it's ing-modifier, then I am confused with what subject the "finding" is attached.

Also how in future we differentiate if its a noun+modifier or ing-modifier. I guessed on this questing and got right..luckly. But in GMAT, what should be my approach.

One question for expert: is "Baltic Sea sediments" by default wrong?

Am not an expert but I think you have a very good point. In "Baltic Sea sediments", the noun is "sediments" and so, "Baltic Sea" is used as adjective. But that does not seem to be correct usage, because "Baltic Sea" is a noun. I mean..we can have "coarse sediment", "fine sediment", "alluvial sediment" etc. , but we can't have "Baltic Sea sediments" because "Baltic Sea" is not a characteristic or a property of the sediments.

Experts, is my thinking correct?

An independent sentences + comma(,) + a noun (findings) + an adjective (consistent) ...

All three, the comma, noun, and adjective, are confusing.

I have ever seen like this sentences?
which kind of grammar ( sentence structure or etc...) is this?

I am elaborating choice D in full:
Scientists have observed large concentrations of heavy-metal deposits in the upper twenty centimeters of sediments from the Baltic Sea, findings (findings is an appositive modifier standing for large concentrations of heavy-metal deposits) (that are) consistent with the growth of industrial activity in the area. The highlighted portions are required to be understood.

Thank you so much for clarification. Appreciated.
After we omit the subject pronoun [that] and the be form of the verb [are], the adjective clause [that are consistent with the growth of industrial activity in the area] becomes the adjective phrase [ consistent with the growth of industrial activity in the area ] that should modify the noun [ findings]. However, I thought whenever we have a single adjective, not participial adjective, such as consistent, beautiful, nice...etc, the adjective should be moved to its normal position in front of the noun it modifies. For example:

The books that are new are very expensive.
The new books are very expensive. ( the adjective [new] is moved to its normal position)
The books new are very expensive. ( It seems incorrect)

Can someone help me in split5). Can I make the split of "Of the baltic sea sediments" vs "sediments from the Baltic Sea"? thanks!

Split1) Modifier. Wrong modifier after the comma. "which" and "where" refers to sediments incorrectly. The subject of the sentence is scientist's observation = singular noun. Also, Baltic Sea sediments is not a place = it cannot be followed by "where". A and B are out.

Split2) In C "It" has not logical referent. C is out.

Split3) "there" has no clear referent. A and E are out.

Split4) Logical Prediction. Look at E, it says that sediments....are consistent with the growth of the industrial activities. The original sentence says the "findings are consistent with..." so, the logic in E is changed.

Split5) "Of the baltic sea sediments" vs "sediments from the Baltic Sea". I prefer to start with "sediments from the Baltic Sea" because "of" preposition + noun + preposition + noun = complete thought. A, B and C are out.

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 - Which refers to sediments and thus creates a meaning issue - The sediments alone are not "consistent with the growth of industrial activity" however - it's the "large concentrations" of these sediments.
(B) Baltic Sea sediments, where the growth of industrial activity is consistent with these findings - Where should refer to a place but sediments are not a place
(C) Baltic Sea sediments, findings consistent with its growth of industrial activity - No logical reference for pronoun its ; Logically, it should be the area around the Baltic Sea, but a noun indicating such an area is not present in the sentence.
(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 - it is not clear what the word consistent describes ; where is "there"? The only location mentioned is the Baltic Sea , but the growth of industrial activity didn't happen in the Sea.

(A) Baltic Sea sediments, which are consistent with the growth of industrial activity there - LARGE CONCENTRATIONS OF SEDIMENTS ARE CONSISTENT WITH THE GROWTH OF INDUSTRIAL ACTIVITY WHEREAS THIS OPTIONS IMPLIES THAT SEDIMENTS (BECAUSE OF THE USAGE OF WHICH) ARE WITH THE GROWTH OF INDUSTRIAL ACTIVITY . INCORRECT.
(B) Baltic Sea sediments, where the growth of industrial activity is consistent with these findings - WHERE I SWRONGLY USED FOR SEDIMENTS. CORRECT USAGE OF WHERE IS FOR PLACE OR LOCATION
(C) Baltic Sea sediments, findings consistent with its growth of industrial activity - 'ITS' HERE IMPLIES TO BALTIC SEA, MEANING BALTIC SEA'S GROWTH. WHEREAS THE ORIGINAL SENTENCE SENTENCE SUGGESTS THE GROWTH OF INDUSTRIAL ACTUVITY RATHER THAN THE GROWTH OF BALTIC SEA
(D) sediments from the Baltic Sea, findings consistent with the growth of industrial activity in the area - CORRECT. BECAUSE THE FINDINGS THAT THERE ARE LARGE CONCENTRATIONS OF SEDIMENTS ARE CONSISTENT WITH THE GROWTH OF INDUSTRIAL ACTIVITY. BEST OPTION
(E) sediments from the Baltic Sea, consistent with the growth of industrial activity there - MODIFIER 'consistent with the growth of industrial activity there' IS AMBIGUOUS. WHAT IS CORRECTLY CONSITENT WITH GROWTH OF INDUSTRIAL ACTTYNCENTRATIONS??

(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

Baltic Sea sediments is incorrect as it gives idea that these are some special type of sediments so A,B,C gone.
In E, consistent.... is incorrectly modifying Baltic Sea.

In D(correct choice), findings....is appositive which correctly refers to large concentrations...deposits.

Expert,

I went through all the posts but I am unable to find clear answers for my doubts below.

1. In the original sentence, "which" refers to??
-- I think which refers to "concentrations of deposits" because we have a long prepositional modifier after concentrations.
Please confirm if my understanding is correct. I find this to be inconsistent with e-gmat solution where they mentioned that "which" refers to "Sediments".

2. Whats the real difference between "Baltic sea sediments" and "Sediments from baltic sea" ??
