After reading this text and looking at the picture, which new idea can Jillian form about Delicate Arch?

Delicate Arch was probably called "Cowboy Chaps" because it looks like a pair of pants a cowboy would wear.
It was probably very difficult for Olympic runners to pass through Delicate Arch.
It is not likely that other natural arches like this are found anywhere else in the world.
Arches are perhaps the only landforms made by wind and water.
