I am trying my best. Cant seem to get an answer. I will keep trying. Till then, I request others to try and post solutions here as well. Thanks.

Oh God! Why are you complaining, Anonymous? Post the answer if you know. Even if he gets the green check mark by cheating how does it matter to you eh? As you said, its a "non-credit" course. Quit acting like an ass.
