Answer
We can rank the points in order of gravitational potential energy, from greatest to least:
$A \gt B = D \gt C \gt E$
Work Step by Step
If the skier is at a higher vertical position, the gravitational potential energy is greater. The gravitational potential energy is a maximum at the highest point, and the gravitational potential energy is a minimum at the lowest point.
We can rank the points in order of gravitational potential energy, from greatest to least:
$A \gt B = D \gt C \gt E$
