You ask questions in a very rude way. I'm going to let you figure this one out by yourself. Duncan Murdoch Sorry, Professor. Murdoch, I did not realize my way of asking questions was rude, and I didn't mean to offend. Would you please give me some hints and help me solve the problem if there is still possibility?
