We can simply get rid of choices using - in isolation- as being wordy; A, C and E are out.
Between B and D, the critical point is whether we need the -were– after - than – Yes we do need;’ or else, the comparison turns out to be between Europeans and Aleuts rather than between the isolation of Bering Inuits and isolation of Aleuts

B is bad comparison while D puts it down correctly and hence the right answer

daagh,

Good work on this problem. One quick note about A,C, and E:

Although "in isolation from" is wordy, "wordy" isn't really a clear grammatical rule. I generally advise people to be a bit more specific when ruling out answer choices on the GMAT. If there is a clear grammatical rule (subject-verb agreement, pronoun ambiguity, parallelism, etc.) then always use that before crossing off an answer for "wordiness," "unclear meaning," or "concision." Using this strategy will increase accuracy during the test, but more importantly it will give studiers more direction in their studying because it will show them what grammatical rule they found (or didn't find) and
allow them to study that specific rule.

In this case, the specific rule related to A,C, and E is idioms. (see chapter 9 in the Manhattan GMAT Sentence Correction Guide, if you have it). "Isolated from" is a correct idiom, but "in isolation from" is not.

If idioms are tough for anybody out there, make some flashcards. Like geometry, idioms simply have to be memorized.

Straight D.

Idiomatic form of 'Isolated' is 'is isolated from contact with' .... hence B and D remain.

D maintains parallelism. hence correct
