a. swim as far as you can from the shore until the water pulls you along
b. ask a friend to go in the water and see what direction she travels
c. watch the movement of a stick or a leaf on the water
d. wade in the water and see if you are pulled in any direction
C. you dont want to risk you or your friends life just to test water currents. despite them not looking so, they can be really dangerous quickly pull you under water or away from shore. hope that helps
