Which term best describes the action 'roll' in the Green Machine instruction?

• A. Hit play
• B. Mute all
• C. Record
• D. Slow playback

Answer: (A)

Rolling a media item is about starting motion and getting it to run. In most control interfaces, that means pressing the play control. So the term that fits best is pressing play. It describes initiating the playback so the media begins moving forward, rather than muting audio, recording, or slowing down the speed. The other options would do different things—silence audio, capture input, or reduce speed—none of which capture the idea of the media starting to move.
