There should be no answer here. Teachers or classmates can do it themselves. No, let your classmates tell you about it, which is helpful for your study. The answer can only be solved temporarily.

You still have to do your homework by yourself. Asking for answers is a bad habit. Do your own homework, so that you can have a sense of accomplishment. Who can give you the answer if you don't even send out the questions? Ask teachers and classmates more, and your grades can be improved.
