Can I replace "which" with "those" here?
- What sort of places?
- Well, obviously it varies, but always places of historical interest and also **which** offer a variety of shopping, because our students always ask about that.

Does the "which" here refer to "places"? As a relative clause?

Can I replace it with "those"?

Answer

You are correct.  "Which" is used as a relative pronoun in this sentence.  It refers to "places".   You can not REPLACE it with "those", however, adding "those" improves the sentence, in my opinion.
