Which statement is true regarding the early sound integration?

• A. Plane Crazy and Gallopin' Gaucho lacked fusion between sound and pictures
• B. Steamboat Willie had no audio
• C. All three had the same level of fusion
• D. The animation did not use any synchronized music

Answer: (A)

The main idea is how tightly sound is joined to the animation, not just whether there is sound. Steamboat Willie is the clear example of true synchronization: the music, sound effects, and any on-screen actions are timed to the animation, so the audio and visuals feel like a single, coordinated performance. Plane Crazy and Gallopin’ Gaucho, while early experiments with sound, did not achieve that same level of fusion—some prints had less precise timing, and in some cases the sound wasn’t as tightly integrated with the action. So the statement about Plane Crazy and Gallopin’ Gaucho lacking fusion captures that distinction, whereas Steamboat Willie exemplified synchronized sound. The other options fail because Steamboat Willie did have audio, and the three shorts did not share the same degree of synchronization, nor did the animation rely on no synchronized music.
