I am concerned that this question and the other ones similar to it are part of a major assignment you have been given that counts towards your final grade. MHF olicy is to not knowingly help with such questions because they are meant to be your own work.

Thread closed (you can discuss the matter with me via pm if the situation happens to be different to what I think it is).
