In a subclass, may the overridden method's scope be altered?
What keyword is used if a subclass needs to call a method in a superclass?
You have a method that requires an argument that is an instance of the superclass, and it expects you to provide it. It will function properly if you provide it with an object of a subclass rather than a superclass. Is it even possible? Where is the value in that?
