What is a moving picture?

• A. A still photograph
• B. A sequence of images that create the illusion of motion
• C. A painting with motion lines
• D. A single frame video

Answer: (B)

A moving picture is created by showing a sequence of images quickly enough that your brain perceives motion. Each image is a frame, and when frames flash by at a brisk rate—around 24–30 frames per second in film or higher in video—the eye and brain blend them into smooth movement. That’s why cartoons, films, and animations feel like they’re moving rather than just being a single moment.

Why the other ideas don’t fit: a still photograph is just one image with no motion. A painting with motion lines suggests movement but remains a static artwork. A single frame video isn’t a standard concept because video relies on many frames to convey motion; a single frame wouldn’t show movement over time.
