Check This
=============
106.Inuits of the Bering Sea were in isolation from contact with Europeans longer than Aleuts or Inuits of the North Pacific and northern Alaska.
(A) in isolation from contact with Europeans longer than
(B) isolated from contact with Europeans longer than
(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.
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.

The correct answer[spoiler=]is D.

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

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 :P

A. in isolation from contact with humans longer than
B. isolated from contact with humans longer than
Here in option B ,it changes the meaning of the sentence.It means the woodland sub-species were isolated from contact with humans longer than they were isolated from contact with their marsh cousins or the tree-dwelling sub-species.
C. in isolation from contact with humans longer than were
D. isolated from contact with humans longer than were
This option clearly states that woodland sub-species were isolated from contact with humans longer than were their marsh cousins or the tree-dwelling sub-species isolated from contact with humans.
E. in isolation and without contacts with humans longer than

Putting B in the original sentence we have

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

The above sentence is ambiguous as it can mean two things

1) The woodland sub-species were isolated from contact with humans longer than they were from either their marsh cousins or the tree-dwelling sub-species. - intended meaning

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

To remove this ambiguity we need the helping/linking verb "were" as is the case in D. (Helping verbs such as was, were, do , have etc are useful in removing ambiguity )

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
