There are question in my textbook:
The CDs in that music shop ____ we poked our heads into last week are on sale now.
(A) whose (B) what (C) which (D) where
The answer is (C). I want to know if there is no "into" in the question sentence the answer become "(D) where"?
I mean, is it ok to say "The CDs in that music shop where we poked our heads last week are on sale now."?
