def can_update_answers(self):
<EOL>return True<EOL>
Tests if this user can update ``Answers``.

        A return of true does not guarantee successful authorization. A
        return of false indicates that it is known updating an
        ``Answer`` will result in a ``PermissionDenied``. This is
        intended as a hint to an application that may opt not to offer
        update operations to an unauthorized user.

        return: (boolean) - ``false`` if answer modification is not
                authorized, ``true`` otherwise
        *compliance: mandatory -- This method must be implemented.*
