Which term best describes a broad category of vehicles capable of flight?

• A. Aircraft
• B. Engines
• C. Propellers
• D. Landing gear

Answer: (A)

The key idea is distinguishing a broad category from individual parts. Aircraft is the term that names the entire class of vehicles designed to travel through the air, including airplanes, helicopters, balloons, gliders, and more. Engines, propellers, and landing gear are specific components that may be found on aircraft, but they describe pieces of the system rather than the whole category. Some aircraft fly with engines and propellers, others rely on buoyancy or other means, so aircraft correctly covers all flight-capable vehicles.
