Ray wants to learn how to replace the chain on his bicycle. He processes information best when he can watch and listen as something is being completed. Which medium would best help Ray in this situation?

Ray learns best by both watching and listening while a task is being done. A video can show the chain-replacement process as someone explains or demonstrates each step. A podcast provides sound but no visuals, while the diagram and brochure do not show the repair happening in real time. The best choice is C, a video demonstrating how to repair a bicycle chain.
