Subclasses will normally want to override the more specific methods {specific_feedback()}, {general_feedback()} and {correct_response()} that this method calls. param: question_attempt $qa the question attempt to display. param: question_display_options $options controls what should and should not be displayed. return: string HTML fragment. |
