Yeah I know but it would help out a lot if you could please help me

so ... what are your answers?

All I need are the correct answers so I can see if I got them right or not. Then I can figure out the rest on my own. Please just help me out. Thank you.

That's not how it works ... you are expecting too much for someone to labor through your 25 questions and give you the correct solutions.

You stated in your original post that you answered all of them, and I asked for you to share those results. I see your refusal as a lack of reasonable effort on your part.
