Giving 20 points for all 4 answered!!! i just want to give away points at this point

Explanation:

#1. The first one would be both because In rowing, the action is the rower pulling the oar through the water, and the reaction is the boat moving the opposite way.

#2. is reaction because for every action force there is an equal and opposite reaction force

#3. is reaction

#4. is action
