A fire engine and an ambulance are examples of ________ and ________ units.

A fire engine and an ambulance are examples of ________ and ________ units.

• A. Primary, Secondary
• B. Fire Department, Rescue
• C. Firefighter, Paramedics
• D. First, Necessary

Answer: (B)

Emergency response vehicles are categorized by the agency that operates them and by the function they perform. A fire engine is a classic Fire Department unit used for firefighting, while an ambulance delivers emergency medical care and patient transport, fitting the Rescue (or rescue/EMS) unit role that handles extraction and medical救 services. So together they represent Fire Department units and Rescue units. The other pairings don’t fit because they describe personnel rather than the vehicle type, or use nonstandard terms like Primary/Secondary or First/Necessary.
