  Comments:
        Bryan paper was the only one recieved outside on our group
(Chris Accidently did this problem), but his answers was typed and well
worked out.

INSTRUCTOR'S COMMENT:  Bryan's proof needed a minor addition to establish
that the argument goes BOTH WAYS.  ("P and Q are equivalent" means:  
If P is true, then Q is true; and if Q is true, then P is true.)
