再问885-c-4

4.                 Virtually undisturbed for the last three centuries on their starkly beautiful islands near the edge of the Arctic Circle, the inhabitants of the Lofotens have evolved folkways and a life-style that bring warmth to their harsh environment.

(A) the inhabitants of the Lofotens have evolved folkways and a life-style that bring warmth

(B) the inhabitants of the Lofotens have evolved folkways and a life-style that brings warmth

(C) evolving folkways and a life-style were evolved by the Lofotens inhabitants to bring warmth

(D) evolving folkways and a life-style brought warmth to the Lofotens’ inhabitants as well as（A）

我当时选了b，现在任不明白that为什么不能只是修饰life style。

记得that一般是就近指代，而     A and B，which这种形式which指代A and B

                                                                                                         A ，and B which 中which 指代B

而这道题中that从什么地方可以看出指代前面两者呢？

是不是为了保证句意而通过主谓一至来强制指代呢？
