+our plan of approach.
+
+The proposal includes the problem addressed by our program,
+explanations of prior literature and work on similar projects,
+an outline of our plan for designing and implementing the program,
+the intended benefits of our program,
+our planned approach,
+how we will evaluate our success,
+and our qualifications.
+
+If you have any further questions or comments, please contact us at
