这个倒装是怎么解释呢？

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

我选的是B，当时考虑本来应该有一个系动词were，但是不是因为平行关系给省略了也可是呢？就选了B。

D选项里面were放在了Aleuts和Inuits的前面，这里为什么倒装呢？语法上怎么解释，请求帮助~~~

这里加上were 是避免产生歧义，因为Aleuts or Inuits of the North Pacific and northern Alaska 可能理解为with 的宾语，与Europeans 平行。所以加上were，就可以确定是主语的比较，而不是介词宾语的比较。
