In this exercise we have to rewrite the sentences provided using the relative pronouns. We have to keep in mind that if the relative pronoun is the object of the relative clause (this means we can drop 'who', 'which' or 'that' if you want) and sometimes it's the subject (we can't drop 'who', 'which' or 'that').
