The woman who lives next door is a doctor.I don't know whose pen this is.The man to whom I spoke earlier was very helpful.The book which I just finished reading was amazing.The dog that barks all night is annoying.Do you know who will be attending the party?She was the one whose car broke down on the highway.I have a friend whom I can always rely on.The dress which she wore to the event was stunning.The students that studied hard received good grades.
