What device produces forward movement of boats by turning a powered wheel?

Explanation:
A paddlewheel propels a boat by turning a wheel with paddles that push water backward. As the paddles shove water toward the stern, the boat experiences an equal and opposite reaction, moving forward. This device is specifically for generating thrust and moving the vessel, unlike other options: movable type is a printing method, canal locks adjust water levels rather than propelling the boat, and tea cultivation is an agricultural activity. So the paddlewheel best fits as the means of forward motion.
