Video Summary

When gear A is turned clockwise, the gear directly connected to it moves counterclockwise due to their connection. The belt-connected gear also moves counterclockwise, causing the larger gear on the left side to move clockwise. This clockwise motion turns a pulley counterclockwise because of a crossed belt, raising box number two. On the right side, the large gear turns clockwise, causing the small gear to move counterclockwise, and the connected pulley clockwise, lifting box number three. Therefore, boxes two and three move upwards, making the correct answer B.
