Answer 1

The teacher asked such a difficult question ___ no one in the class could answer.
A. which B. that C. so D. as
答案：D
解答：这是个含有定语从句的主从复合句，先行词（a difficult question）被such或者the same修饰时，关系代词用as，并且关系代词在定语从句中作answer的宾语。
翻译：老师问了一个班上没有人可以回答的很难的问题。

解惑：如果从句中answer有宾语，那它就不是定语从句了，而是结果或程度状语从句了，即：The teacher asked such a difficult question _B_ no one in the class could answer（it）. A. which B. that C. so D. as
