我想知道这话的to which引导的是定语从句？我感觉像同位语从句.麻烦英语高手解答一下，谢谢了。

Question

He bombarded Catherine with questions to which he should have known the answers.这句的to which是引导定语从句的吗？

Answer 1

He bombarded Catherine with questions to which he should have known the answers.
什么样的questions?——to which he should have known the answers.不确定翻译过来看看，什么样的问题？是他本应该知道答案的问题。所以是定语从句。
这句话怪就怪在用了the answer to 这个短语，而且倒置了这个搭配，所以你才会看不懂，疑惑。
