Suppose that we used one of the staircases in Building 76 to make a ski slope: we took it outside and covered it with snow.
Would this slope (if we could extend it for a few hundred meters) count as a beginner, intermediate, or expert slope? You can use this as a very very rough guide:
beginner angle < 12 degrees intermediate angle < 12 degrees < 30 degrees expert angle > 30 degrees
