Abstract: A method and apparatus for encouraging a student to continue practicing skills until mastery of the skills is achieved. The method and apparatus present assigned exercises sequentially to a student, and evaluates the student's response. An assignment comprising a finite number of questions, a maximum number of attempts to answer each of the finite number of questions, and a required minimum number of correct answers to the finite number of questions is designed for a user. A learning device presents the user with a question from the finite number of questions that has not been attempted by the user. If the user supplies an incorrect answer to the question, the user chooses to either accept the incorrect answer, or to repeat an attempt to answer the question with new parameters.

Abstract: A method for improving the palatability of a livestock feed or companion animal food product comprising a basal composition containing unsaturated fatty acids that oxidize to form aldehydes or ketones by contacting the basal composition with a source of bisulfite anions so that any aldehydes or ketones present form organosulfite salts. Bisulfite-treated livestock feed and companion animal food products, and palatability enhancing composition containing a source of bisulfite anions are also disclosed.
