Still, in that case, how can you answer the questions, or understand the course you are taking? The idea behind homework is that it should make you think about what you have learned... so if you can supply some answers and why you think those answers might be correct, then that is a start, and people will be more willing to help.

I answered to other 80 questions, but I couldn´t find something about these 7. I understand, but searching with my poor English is really difficult. It is not my homework, I found these questions on the internet.
