Asking questions?

Hello guys, so last week we are doing asking and answering questions. So we have to know why do we have to ask and answer questions. Why? Because we need to know if we really know the story or understand the story well. for example...

Our teacher gave us a partner to do this and we have to ask a question to our partner if they really do understand the story well. Doing this make me know the story well and asking questions are really good so you would know and understand  what is the story is about.
