The correct answer is: D. teacher : school
A waitress is a person who serves food and drinks to customers in a restaurant. A teacher is a person who teaches students in a school. Both waitresses and teachers are professionals who provide a service to others. They both work in a specific setting, a restaurant or a school, and they both have a specific role to play in that setting.

is a person who diagnoses and treats illnesses. An actor is a person who performs in plays or movies. A driver is a person who operates a vehicle. An author is a person who writes books. These professions are not as closely related to the profession of waitress as the profession of teacher is.In conclusion, the correct answer to the question “Choose the pair that best represents a similar relationship to the one expressed in the original pair of words. WAITRESS : RESTAURANT” is: D. teacher : school
