question "What are the booking start and end dates of the apartments with type code "Duplex"?"

query SELECT T1.booking_start_date , T1.booking_start_date FROM Apartment_Bookings AS T1 JOIN Apartments AS T2 ON T1.apt_id = T2.apt_id WHERE T2.apt_type_code = "Duplex"

should be T1.booking_end_date not T1.booking_start_date twice
