Read the following passage from "Unbroken":
“As the shark lunged for his head, Louie bared his teeth, widened his eyes, and rammed his palm into the tip of the shark’s nose. The shark flinched, circled away, then swam back for a second pass. Louie waited until the shark was inches from him, then struck it in the nose again.”
Based on the passage, What can you infer about Louie?
