[求助]OG43的疑问

43. In the minds of many people living in England, before Australia was Australia, it was the antipodes, the opposite pole to civilization, an obscure and unimagin­able place that was considered the end of the world.

(A)      before Australia was Australia, it was the antipodes

(B)       before there was Australia, it was the antipodes

(C)      it was the antipodes that was Australia

(D)      Australia was what was the antipodes

(E)       Australia was what had been known as the antipodes

og关于e选项错误的解释： E similarly distorts the original meaning, and the past perfect had been is inconsistent with the past tense used to establish a time frame for the rest of the sentence.

 before Australia was Australia我当这个是固定用法
