Which term describes the conveyor belt-like walkway seen in airports and popularized by The Jetsons?

• A. Moving sidewalk
• B. Sidewalk origin
• C. Hofstadter's Law
• D. 90-90 Rule

Answer: (A)

A moving sidewalk is the term that fits a belt-like walkway that carries people along, typically found in airports. This device is literally a moving belt under a sidewalk-like surface, designed to glide travelers longer distances with less walking. The Jetsons helped fix this image in popular culture, making the idea of a futuristic conveyor belt for human travel memorable. In real life, you’ll see signage that calls them moving walkways or moving sidewalks, which aligns with how they function. The other terms aren’t related to this object—one sounds like a nonsensical origin phrase, and the remaining two refer to timing or productivity ideas rather than a physical airport feature.
