106．Inuits of the Bering Sea were in isolation from contact with Europeans longer than Aleuts or Inuits of the Noah 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

正确答案是D,想问下答案中的were在这里是倒装吗？主语是Aleuts or Inuits of the Noah Pacific and northern Alaska还是Inuits of the Bering Sea?

这个句子要表达什么意思？

than后面were的主语是Aleuts or Inuits of the Noah Pacific and northern Alaska。是谓语前置，但具体原因忘记了。

我对这句话的理解是：相对于Noah Pacific和northern Alaska的阿留申和爱斯基摩人，Bering Sea的爱斯基摩人与欧洲人没有联系的时间要更长。
