To ensure me that you have understood what creative nonfiction is, consider the many things that might fall under this genre. Things that are funny, sad, happy, dark, joyous, incredible, dreary... You do not have to have an example for each of those, but come up with just three examples of creative nonfiction stories that you like, or think you would really enjoy, and say in a sentence or two why it appeals to you.
One key note! Stories "inspired" by true events are not creative nonfiction. Braveheart, while being one of my favorite movies, is what we call historical fiction, with a heavy emphasis on fiction! It contains a basic "flavor" of the time period, but does not attempt any high level of accuracy.
