Will go with choice B.
B seems to be parallel...shielding them xxx, and saving them xxx

Thanks,

Meaning of the sentence was the key here. That's why many people incorrectly marked C.

The melting ice fails to keep them (the artifacts) undetected, shielded from decay and safe from XXX. So narrowed down to choice C and E. I chose C but did a littl more study on the use of "due to" Vs "because of".

"Due to" typically modifies a noun which is closest to the modifier. A quick check is to replace "due to" with "caused by" and see if it makes sense.
"Because of" modifies a verb or a phrase.

Now putting this logic back in the sentence.
" .... melting ice fails to keep them undetected, shielding them from decay due to changing climatic conditions, and safe..."

The noun nearest to "due to" is decay. Is the the decay decay caused by changing climatic conditions? No.

Instead, it modifies the verb "fails" or the phrase the "The melting ice fails to keep them undetected, shielded, .." It answers the questions "why does the ice fail to keep them undetected, shielded, and safe?" because of changing climatic conditions.

Thus, "because of" seems to be the correct usage as in choice E.

Day 10 Question of the Verbal Contest: Race Against the GMAT Club Timer
Please make sure to post a brief reply without revealing your solution to enter the contest!


split "due to' vs 'because of'. We can test 'due to' by substitute it with 'caused by' if it make sense then we should use 'due to':
"shielding them from decay due to caused by changing climatic conditions"
'caused by' makes sense, because 'decay caused by changing climatic conditions', so we should use 'due to'
B and E out.

Structure of sentence:
Glacier and ice patch archaeologists face extreme challenges
....to find,
....[to] document,
....and [to] conserve artifacts
when melting ice fails to keep them
....undetected,
....shielding them from decay due to changing climatic conditions,
....and safe from misappropriation.

'undected', 'shielding' and 'safe' - three elements that should be parallel because they describe in which condition melting ice fails to keep them
(we can't use 'shielding' because it will be modify previous clause 'fails to keep' so we need to use 'shielded')

C is answer

D. shielded from decay due to changing climatic conditions, and saving them

E. shielded from decay because of changing climatic conditions, and safe

undetected, shielded ..... and safe ( parallel construction) scanning made it between C and E . due to vs because of

no sure of exact reasoning behind choosing one over other.

I selected C and here are my 2 cents:

"changing climatic conditions" is a noun phrase... shielded from decay "caused by" changing climatic conditions.

"shield-ing" will look like a verb-ing modifier qualifying the previous clause.. which we dont want..

undetected, shielded and safe.. looks good..

Dom

Ok so lets evaluate each option....

A. uses "shielding" now this is a modifier that must modify: "fails to keep them undetected" = "detected". Now by analysing meaning how can "shielding" lead to "detected". This does not make sense. Hence use of Shielding is incorrect.

B. uses Shielding again and use of "Them" is ambiguous.... incorrect

D. use of "Them" is ambiguous.... incorrect

C. (Due to) v/s E. (because of)

Due to modifies nearest noun "The Decay"
Because of modifies "Fails to keep them ... shielded from the decay"

now we are in middle of a list: undetected, shielded, and safe. Some middle element cannot contain "because of" that can potentially modify the whole list. So "because of" should have been present either at beginning or at the ending of list. For this reason E is Incorrect

Ans is C
Also try replacing "due to" with "caused by". It sounds fine.

Heey, please is the use of '' due to '' appropriate in the sentence (C) ? because, as far as i know, "due to" must follow a form of the verb ''to be '' ..

Hello issamL

"due to" in C is correct:
We can test 'due to' by substitute it with 'caused by' and if it make sense then we should use 'due to':
"shielding them from decay due to caused by changing climatic conditions"
'caused by' makes sense, because 'decay caused by changing climatic conditions', so we should use 'due to'

If 'due to' does not make sense we should use 'because of'

"Due to" is an adjective and correctly refers to "decay". "Because of" is an adverb and should be used to refer to a verb. Eliminate B and E.

Present participle "shielding.." should refer to the previous clause or the subject of the previous clause - incorrect. Eliminate A.

Present participle "saving.." should refer to the previous clause or the subject of the previous clause - incorrect. Moreover "saving" is not parallel with "shielded" and "undetected". Eliminate D.

C is the correct answer. Parallelism between "undetected", "shielded" and "safe" is alright. A past participle used as an adjective can be parallel to another adjective.

Archaeologists face extreme challenges to find, document, and conserve artifacts when melting ice fails to keep them undetected,_______________________________, ________ from misappropriation.

A. shielding them from decay due to changing climatic conditions, and safe

C. shielded from decay due to changing climatic conditions, and safe

E. shielded from decay because of changing climatic conditions, and safe

I narrowed the options down to (A) (C) (E) because I notice the parallel structure "keep them undetected and safe from"
My logic was the, __________, part is modifying melting ice; this is why I went to (A)
I was debating between (A) and (C), I believe "because of" in (E) is not as efficient as "due to"
