premise: A skater performs a stunt off a cement wall covered in graffiti.
hypothesis: The city youth enjoying his skateboard, executing from the wall he painted.
explanation_1: Anyone can be a skater, not just a city youth. A skater can use items other than a skateboard such as roller skates. Just because a skater is in front of a wall covered in graffiti doesn't mean that he painted the wall.
explanation_2: Not all skaters are city youth. The skater did not necessarily paint the wall.
explanation_3: Just because a skater performs on a wall cover in graffiti does not mean he painted it.
