B: Inuits of the Bering Sea were isolated from contact with Europeans longer than Aleuts or Inuits of the North Pacific and northern Alaska.
This wording allows for two logical interpretations:

1. Inuits of the Bering Sea were isolated from contact with Europeans longer than were Aleuts or Inuits of the North Pacific and northern Alaska [isolated from contact with Europeans].
2. Inuits of the Bering Sea were isolated from contact with Europeans longer than [Inuits of the Bering Sea were isolated from contact with] Aleuts or Inuits of the North Pacific and northern Alaska.

Since the intended comparison is not crystal clear, eliminate B.

OA: Inuits of the Bering Sea were isolated from contact with Europeans longer than were Aleuts or Inuits of the North Pacific and northern Alaska.
Here, the usage of were makes the intended comparison crystal clear:
Inuits of the Bering Sea were isolated from contact with Europeans longer than WERE Aleuts or Inuits of the North Pacific and northern Alaska [isolated from contact with Europeans].

Guru, can you comment on the split here: isolated vs in isolation.
how to choose?

Hi Aflaam ,

I eliminated option A,C, and E because in isolation is not correct idiom.

Correct Idiom -- IS ISOLATED FROM

@Experts , please correct me if I am wrong.

Thanks,

SJ

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
