182쪽에 8번 문제에서A : I'm not sure whether to buy a sofa or an easy chair.B : Buy ______ you think will be most comfortable.(a) which (b) what (c) that (d) whichever 인데의문대명사 which는 못쓰는 건가요?
which가 관계대명사면 당연히 안되는데, which가 의문대명사로 쓰일 수도 있다고 하더라고요. He could tell which is the original between the two paintings. 처럼요. 그래서 질문드린겁니다..ㅠ
