Shielding, looks like modify the previous clause.
But it is not a cause and effect, it looks wrong modifying entire thing, .
shileding must refer to melting ice. so option A and B wrong.
so shielded is correct in this usage.
here parallesim shielded from and safe from is correct.
so D wrong.
In between C and E , due to vs because of.
Because of prefered more than due to.
Because of must follow noun or noun phrase. in Option E is correct
.
But if we look meaning wise, due to used for caused by it means, shileded from caused by climatic changing condition.
Even though Option E looks correct grammatically, Option C wins by meaning.

So option C is correct.

This one is tough one. This is a real good question. This question depends mainly on meaning of the sentence. This particular type of questions need underdstanding of fraing sentence with two different times in discussion.

Is there any ambiguity with the un-underlined part?

Glacier and ice patch archaeologists face extreme challenges to find, document, and conserve artifacts when melting ice fails to keep them undetected

"them" could refer to archaeologists or artifacts, no?

IMO, parallelism, idiom usage and pronoun ambiguity are the main issues here. The underlined portion with the parallelism marker ‘and” lacks symmetry with a participle phrase on the left and an adjectival phrase on the right. There should be another patricipial phrase on the right side too. Any choice containing ““and safe” is incorrect. Dump A, C and E. In addition in A, the pronoun ‘them” is ambiguous without required clarity whether it refers to archeologists or the artifacts.

Between B and D, the correct idiom to use will be ‘due to” since the decay is caused by climatic changes and B can be dropped. Further, B uses the dubious pronoun “them”.

One might now construe the correct choice.

Hi,
Although you have been associated with Kaplan and been in this field for some time, and so you should be on the correct lines, i have few observations..
1)Any choice containing ““and safe” is incorrect.... agreed..
2) the pronoun ‘them” is ambiguous without required clarity whether it refers to archeologists or the artifacts. ... agreed 'them ' is ambiguous but them is already used in non underlined portion and 'them' is referring to the same thing on every occasion as the structure of sentence states ... so B cannot be eliminated on this ground..
3) the correct idiom to use will be ‘due to” since the decay is caused by climatic changes and B can be dropped. As per various other institutes and few examples in OG, 'due to' should be preceded by 'to be' verb. so here because of should be correct

shielding ... and saving.. are basically effects of the melting ice fails to keep them undetected

A. shielding them from decay due to changing climatic conditions, and safe : Incorrect - Not parallel

B. shielding them from decay because of changing climatic conditions, and saving them Incorrect ( The subject of the IC should be also the doer of the ing part. Do the archaeologist shield from decay ? No, the ice does. )

C. shielded from decay due to changing climatic conditions, and safe : Incorrect - Not parallel

D. shielded from decay due to changing climatic conditions, and saving them : Right answer , both modifies the pronoun them... and them has only one antecedent, which is artifacts

E. shielded from decay because of changing climatic conditions, and safe : Not parallel.

Hi daagh, i think , logically them has only 1 antecedent imo, which is artifacts ,logically . it doesn't make sense 'them' referring to archaeologists. Even D has pronoun them in the choice. pls clarify

Hi
Thank you for your instant response. On the points, which seem to have some disagreement-

1, Admittedly, the pronoun ‘them’ is vulnerable to ambiguity in the underlined portion. Well, that should be sufficient cause to dump it, even though in an another place, the same pronoun may mean definitely the artifacts. The idea on the D-day is to quickly reach the correct choice, rather than getting stuck unduly on some factor; but more importantly, the ambiguity was only an additional point.

Coming to the use of idiom, it is my perception that ‘due to’ is used to modify a noun, ‘the decay’ as in this case and it rightly replaces the idiom “caused by”

IMO, ‘because of’ is used when a verb precedes it and therefore, the idiom modifies the verb. In the context, there is only a decay that is due to or caused by climatic conditions; Let me keep my fingers crossed until the OA is out; In any case, since you seem to have different ideas, may I have privilege of asking you what your call is

There is a 3-2 split among answer choices between shielding and shielded.
Shielding is done by and refers to archaeologists correctly. Eliminate options C,D and E since shielded refers incorrectly as Arch's are shielded and by whom is dubious.
Arch's do two things shielding and saving the artifacts. So these should be parallel. Due to incorrectly refers shielding action whereas it can refer to only noun. So usage of because of is correct here.
Also safe from misappropriation wrongly indicates that arch's are safe.

Hi daagh,
we both have homed on to two final choices as B and D..
I have gone with B for following reasons..
a) I think 'them is correctly referring back to artifacts as artifacts are the object here and archeologists are the subject here and 'them' should be referring to object, when we have two nouns to refer to and the meaning conveys to that end.
b) shielding ... and saving.. are basically effects of the melting ice fails to keep them undetected, so both shielding and saving should be parallel, which is missing in D..
c) D omits them in one clause but keeps it in the second part, so it is not following parallelism.
d) i believe decay is due to changing climatic conditions would have been correct..

But again as you have said, we all have our own perceptions depending on the experiences with the type of Qs we have had earlier. and with so much of material floating around, difficult to home on to something that has not been clearly spelt out by the official GMAC. lets wait for OA. if otherwise, it will teach a new thing.

This discussion is getting more interesting; In D, you do have ‘ them” but it is not vulnerable to ambiguity, as it is pointless to think that it may refer to saving architects from misappropriation. The question of vulnerability is there in B' only in the first underlined pronoun and not in the second. At least that is what my perception is since I believe, the choice can be dumped more importantly for using a wrong idiom ‘because of’. Have I made myself clear?
But still, why don’t you post your choice also to make the topic more revealing

hi daagh,

i do agree that due to is appropriate here. so not going with B. i am also going with D. But I didn't understand how you rejected B because of 'them'

its intense now. battle between two heavyweights (chetan and daagh)

after reading the question again, cant the parallelism be in this way...

fails to keep them undetected ............ and (fails to keep them) safe .... ??

Here is my thought. The meaning of this sentence seems to be playing a big role. The author is trying to talk about the artifact here. Shielded does not fit into the sentence here because the climatic changes is not actually preventing shielding, so shielded would mean it was already shielded and not done by the archaeologists. So Shielding / saving fits in well as they are trying to shield and save them. So I am going with
B.

Hii,
My take on this:

I took the structure method to solve this one

Glacier and ice patch archaeologists face extreme challenges to find, document, and conserve artifacts
when melting ice fails to keep them undetected,MODIFIER1,and MODIFIER2

We have to keep modifier1 & modifier2 parallel.

Look at the dependent part in the non-underlined portion: when melting ice fails to keep them undetected. Here them refers to artifacts so in the subsequent modifiers them will unambiguously refer to artifacts only.

Now coming to structure of modifier. Simply we need to ask a question how ice protects artifacts

Ans: by shielding them from blah blah, and by saving them from blah blah

So got it we need a adverbial modifier to show how melting ice does the protection of artifacts

Hope i caught the view of questn framer.
