@abc.abstractmethod<EOL><INDENT>def get_assessment_offered(self, assessment_offered_id):<DEDENT>
return<EOL>
Gets the ``AssessmentOffered`` specified by its ``Id``.

        In plenary mode, the exact ``Id`` is found or a ``NotFound``
        results. Otherwise, the returned ``AssessmentOffered`` may have
        a different ``Id`` than requested, such as the case where a
        duplicate ``Id`` was assigned to an ``AssessmentOffered`` and
        retained for compatibility.

        :param assessment_offered_id: ``Id`` of the ``AssessmentOffered``
        :type assessment_offered_id: ``osid.id.Id``
        :return: the assessment offered
        :rtype: ``osid.assessment.AssessmentOffered``
        :raise: ``NotFound`` -- ``assessment_offered_id`` not found
        :raise: ``NullArgument`` -- ``assessment_offered_id`` is ``null``
        :raise: ``OperationFailed`` -- unable to complete request
        :raise: ``PermissionDenied`` -- authorization failure occurred
