교통 규칙을 기반으로 구축된 추론 문제

A single continuous fixed wide shot in a plain, brightly lit test room, filmed like an unedited behavioral experiment. At the start, a red cube is on a table, a drawer is closed, a lamp is off, a chair sits precisely inside a taped floor outline, a hat hangs on a wall hook beside a bare mannequin, and a door is open. One person quickly performs six clearly separated actions in this exact order: places the red cube on a shelf, opens the drawer, turns on the lamp, moves the chair away from its taped outline, takes the hat from the hook and puts it on the mannequin, then closes the door. An off-screen instructor clearly says, "Undo only the last three actions." The person pauses briefly, understands the instruction, and carries it out exactly. No cuts, no time jumps, no extra actions, no additional dialogue, realistic synchronized room sounds.
