12,105 PointsShouldn't System.Exception be a "catch all"? This test is saying that only System.Exception can be caught by
System.Exception. The quiz is saying if the exception thrown is too specific then System.Exception wont catch it.

You're right that it would typically serve as a "catch all", but only if it part of the "catch" chain.

231,198 PointsOh, since "OutOfBoundsException" is derived from "TreehouseDefenseException", then that catch will handle the throw before it reaches the "catch all". The "System.Exception" would catch it only if no other catch placed before it handled the event.
