(C) in isolation from contact with Europeans longer than were
(D) isolated from contact with Europeans longer than were
(E) in isolation and without contacts with Europeans longer than
Idiom + Logical predication
The construction in isolation from is awkward；the idiomatic way to express this idea is isolated from．The comparison is ambiguous；it could mean the Bering Sea Inuits were isolated from Europeans 1onger than they were isolated from Aleuts and other Inuits or that they were isolated from Europeans longer than Aleuts and other Inuits were isolated from Europeans．Adding were after than will solve this problem．
[Reveal] Spoiler:
A In isolation from is not the correct idiom；the comparison is ambiguous．
B The comparison is ambiguous．
C In isolation from is not the correct idiom．
D Correct．The idiom isolated from is correctly used in this sentence；the comparison is clear and unambiguous．
E In isolation…with is incorrect and confusing；the comparison is ambiguous．

Neeshpal,

You are taking the question in a wrong way. You are trying to compare the isolation of woodland sub species from other species. However, this question compare the isolation of woodland from human contact with the isolation of other species from human contact.

So, it'll be like The woodland sub-species were isolated from contact with humans longer than other species were.

That's why the correct ans is D.
---------

If someone like my post, consider it for Kudos so that my Kudos account get started

section after "than" is inverted. You can read it as "either their marsh cousins or the tree-dwelling sub-species were".

Meaning : duration of isolation from humans for woodland sub-species was longer than for their cousins or tree-dwelling sub-species.

(A) in isolation from contact with humans longer than
Mistake-1: isolate (verb) should be preferred over isolation (noun)
Mistake-2: In this choice it seems that isolation with humans was longer than with other species. change of meaning because of wrong comparison.

(B) isolated from contact with humans longer than
Mistake-1: helping verb 'were' is required. because of missing verb the mistake conveys the wrong meaning as mentioned in mistake-2 of choice A above.

(C) in isolation from contact with humans longer than were
Mistake-1 same as (A).

(D) isolated from contact with humans longer than were
isolate (verb) fine. 'were' is present too.
Lets read it : 'Ws' were isolated....with humans longer than were 'MC' or 'TD' . sounds perfect.

(E) in isolation and without contacts with humans longer than
Mistake-1: same as (A).
Mistake-2: without contacts with human --- complete change of meaning

The woodland sub-species were in isolation from contact with humans longer than either their marsh cousins or the tree-dwelling sub-species.

A. in isolation from contact with humans longer than
B. isolated from contact with humans longer than
C. in isolation from contact with humans longer than were
D. isolated from contact with humans longer than were
E. in isolation and without contacts with humans longer than

I shall go with B

A: 'in isolation from contact' seems wrong idiomatically
C: 'in isolation from contact' seems wrong idiomatically
D: Hmm..this was probably the strongest contender but for some reason I think 'were' is not necessary. It is sort of implied because 'were isolated from contact' comes before either..or. It is similar to a question i did on this forum: 'from the sites of the civilization that flourised at the same time as civilization Nigris...' The sentence did not include 'flourished at the same time as did civilization Nigris..'
E: The two points are not separate..hence no need of And.

What is the OA?
Also, what does IMO stand for? Sorry, I am new to this forum lingo!

Thanks for the briefing Nitya..

I guess we really are poles apart on this one.

Neeshpal, can you give us the official answer?

I go with D also.

I like the verbal questions so much more than the math...

I would go with D as well. This problem is a combination off idiom + parallelism
in isolation from is not idiomatic to me
and the 'were' is required for the parallel structure thus D

The fight is clearly between C and D. S sounds bit awkward. Generally, we say Prisoner are kept in isolation and from is implicit and not used . But in this case, in order to make the comparison work, from is needed and hence, D.

Thanks for the reminder about parallelism. I chose B and will remember why I was incorrect - missing "were."

Can anyone explain the ending part of D. I understand why it is isolated from ( originally chose B ) but I do not understand why it is "than were" rather then "than."

"Than were either" sounds real awkward and weird. "Than" is shorter and concise, B has more brevity than D.

Good question D must be the answer .But i chhose B thinking it to be correct and concise but it omits were and because of that there is a faulty construction . Need to be more careful to notice these traps

If we use the correct form of parallelism than this one is correct.
