There are two quick questions about sudoku puzzle. It looks very long, but you will understand that this is the usual style of puzzle topics if you are good at solving such problems. I need the experimental tutor to help me, and it won't spend you 2mins for each small question if you are good at it. If you need some samples, I could give you some notes and samples, and it might help you to solve questions.

Just paying attention on reading question carefully and answers them as detailedly as you can. Thank you for your attention.ATTACHMENTS
