Two people climbed to the top of the hill. The first person walked a long winding trail with a gentle slope. The second person climbed up a steep set of stairs that went straight to the top. Which person did more work? please explain.

The work in both situations is the same. This is because gravity is a conservative force, so the path length doesn't matter, only the difference between the final and initial positions. The work done by gravity, or the change in mgh, is the same in both situations.
