翻译as it became known

题目

翻译as it became known
The 32-page Vrba-Wetzler report, as it became known, was the first detailed report about Auschwitz to reach the West that the Allies regarded as credible.其中的as it became known是指什么?是说the 32-page reprotwas known as vrba-wetaler report么?
意见不太一致的说，有没有人能给出比较权威的解释？还有the West在这个二战语境下有什么特指么？解决之后追加积分。

答案

32-page,是修饰Vrba-Wetzler report的,我翻译为32页的Vrba-Wetzler报告.as it became known中的it,只的是The 32-page Vrba-Wetzler report,应该是前一个句子的同位语.
