While, sadly, this may be a workbook question and, even worse, suggestive of a
live lab problem, it's an insane thing to do. With one special-case exception,
I've found it wise -- as have many people in large, complex networks -- ALWAYS
to use network with a mask of 0.0.0.0.

The more you allow wide-scope OSPF masks, automatic redistribitution, etc., the
more you expose yourself to questionable information leaking into routing
protocols, and the more difficult you make troubleshooting.
