Answer 1

Wood would create the most friction (think of the texture of wood verses cement and metal) but cement would also cause friction. Metal would provide some amount of friction, but not as much as cement or wood.

Answer 2

Metal, cement, and wood would all apply amounts of friction. However wood will provide the most friction due to its rougher surface compared to smoother surfaces like the cement and metal.
