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

"Which" jumps out at me here. It seems to be suggesting that the sediments are consistent with the growth of industrial activity, and that really doesn't make sense. I suppose you could try to argue that this is some sort of violation of the "touch rule", and the phrase "which are consistent with the growth of industrial activity" reaches all the way back to "large concentrations of heavy-metal deposits in the upper twenty centimeters of Baltic Sea sediments"... but holy crap, that's a stretch. I'm not buying it.

Plus, "there" isn't very clear. The nearest location is the "upper twenty centimeters of Baltic Sea sediments", and that's not where the growth of industrial activity happened. Eliminate (A).

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

The problem is similar to that of (A): "where" seems to be modifying "sediments", and that makes no sense. Eliminate (B).

Quote:
(C) Baltic Sea sediments, findings consistent with its growth of industrial activity

The pronoun "its" jumps out at me here, in keeping with our advice in this week's long-winded Topic of the Week. The only singular noun it could refer back to is "Baltic Sea" -- so "the Baltic Sea's growth of industrial activity"?? That doesn't make sense, either. Eliminate (C).

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

OK, this is pretty nice. It's clearer with the repetition of the word "findings", and "in the area" clarifies that the industrial activity is around the Baltic Sea, not in it. Keep (D).

Quote:
(E) sediments from the Baltic Sea, consistent with the growth of industrial activity there

The only real issue for me here is the word "there." The only location that it could plausibly refer back to is the Baltic Sea, and again, that's not where the growth of industrial activity is happening.

So (D) is better than (E).

IMO its D

in A, which is referring to sediments and hence its deviating the meaning of the sentence.
In A, B and C, Baltic Sea Sediments seems to be the name of a variety of sediments, hence sediments from B.Sea is better,
In D: After the comma, "findings' emphasizes on the scientists study rather than the Baltic sea or the sediments - that's the mistake in option E.

D is the answer for me.

A - ",which" modifier seems to make no sense here. Were the sediments consistent with the growth of industrial activity? And where is 'there'? OUT.
B - Nor Upper Twenty Centimeters or Baltic Sea sediments are a place so we cannot use 'where'. OUT.
C - What is 'its' referring to? Seems to have no antecedent. OUT.
D - Adverbial modifier correctly modifying the scientist's observation + it mentions industrial activity in the area, better than a pronoun with no noun as an antecedent. KEEP.
E - Even if I take this as a noun modifier modifying baltic sea, or sediments - it still makes no sense. OUT.

Waiting for the OA.

D?
"There" has to be somewhere
plus
"what" is consistent?
I think d is the right choice.

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

Baltic sea Sediments ==> Sediments of the Baltic sea ==> Sediments are still in Baltic sea

Sediments from the Baltic sea ==> to me implies that we have brought the sediments from the Baltic sea to some place say
for an example: sediments from Baltic sea were brought to the laboratory to analyse the metal content

Why is it ok to shift from Baltic sea Sediments to Sediments from Baltic sea? Is the act of observing is happening at sea level or at laboratory?

To observe the upper twenty cm of the layer, I guess scientists need to pick up the sediments and test, so sediments from B.Sea is the correct construction.

Hope its clear!

Went with D

A) Baltic Sea sediments, which are consistent with the growth of industrial activity there Baltic Sea sediments are consistent with the growth industry doesnt make sense. Also " there" doesnt make sense.

(B) Baltic Sea sediments, where the growth of industrial activity is consistent with these findings. where should always indicate a place or an area

(C) Baltic Sea sediments, findings consistent with its growth of industrial activity. underline section doesnt make sense.

(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 " there " again

Interesting and hard SC question. Thanks souvik101990 and +1 kudos

A.

_Wrong use of ",WHICH" MODIFIER

",WHICH" seems to refer to "sediments" or even "centimeters ", implying that each of these two nouns is consistent with the growth of industrial activity --> Illogical

_Ambiguous pronoun

What does "there" refer to? "There" does not even have an antecedent.

B. Wrong use of ",WHERE" MODIFIER

",WHERE" seems to refer to "sediments", which is NOT a physical place.

C. Ambiguous pronoun

What does "its" refer to? "its" does not even have an antecedent.

D. The construction of [comma + findings consistent with the growth of industrial activity in the area] is weird. But I guess this structure would be a SUMMARY of what happens in the preceding clause. I am not sure. But I keep D and look for a better option.

E.

_Wrong use of MODIFIER

" consistent with the growth of industrial activity there" seems to modifies Baltic Sea, which can NOT be compared to "the growth of industrial activity"

_Ambiguous pronoun

What does "there" refer to? "There" does not even have an antecedent.

IMO D.

Waiting for OA and OE that explains the weird construction in D.

IMO D
Removes pronoun ambiguity and uses findings which modifies preceding clause .

sediments from the Baltic Sea is preferred over Baltic Sea Sediments.

a. which is vague....which can refer to heavy metal deposits or Baltic Sea Sediments
b. where wrong use...
c. its...what is it referring to
d. correct, finding is consistent with the growth of industrial activity.
e. sediments cannot be consistent with the growth of industrial activity.

D is more clear than C.
"its" in C can refer to Baltic Sea.

Your analysis is very clear, I like it.

(A) ....,which are..... [ In addition to the problems with "which" and "there" as explained by you below, I am finding the use of "are" is also erroneous].

(E) The word ", findings" is missing in E. It is important to have this word from a clear meaning point of view.
