You need to lift a heavy rock using a long plank and a brick as a pivot.
Select the ONE best answer from the options panel.
Place the brick close to the rock so the long end of the plank is where you push.
Place the pivot far from the rock and push very near the rock.
Hold the rope at both ends and push down only.
Remove the pivot and only use your hands.
