So I just finished a quiz and it was easy, but I got two questions I don't understand. My  questions is what is different between hang and hangs? and my another questions is what is the different between giving and given? teacher, what do you think about this grammar and do you think these grammar will help us in the future? Can you tell me why you want us to do those grammar? What is the main goal for us to do? I think some these grammar are hard and some not. And I think you made a good idea, because that way it will help us to remember the grammar that we forgot.
