Answer 1

The person has the greatest potential energy **at the top of the ramp before they begin moving down into the ramp**.

Potential energy is highest when an object is at its highest point in a gravitational field, which occurs at the top of the ramp. As the person descends the ramp, their height decreases, and thus their potential energy decreases.
