一道好像很简单的题——one sc from PR

Before 1934, national records were kept by separate agencies (rather than by a centralized government department, which led to the loss or destruction) of a large number of important.
不知道句中的which是指national records还是cenrealized government department?

困难是弹簧

从语法角度我认为是修饰government department

同意弹簧大哥的意见~~
不过从以上好像讲不通啊!pr的题可真ft~~

piggy sis,

DO NOT probe too deep into PR or Kaplan. Their principles quite differ from OG(ETS).
