OG224

(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

答案选对的，但看E的解释时我没看懂，那位高人能给小弟解答一下

      The awkward phrasing of E further distorts the sense of the sentence: because with cannot idiomatically serve as the preposition for in isolation, the sentence suggests that the Bering Sea Inuits were totally isolated.
