Obligation, Prohibition, and absence of obligation


Conversation: read the conversation and answer the questions.
David: Hey! I went to the university today.

Steve: Interesting. What’s new?
David: I was told about the rules there.
Steve: What are they?
David: Let me first talk about some of the thing we must do.
First, you have to submit your identity card once they ask you for it.
        
  Also, you must attend all the lectures, laboratory classes and tutorials.  And you are required to ask for transfer only before the end of September.
Steve: Oh really! How about the things we mustn’t do?
David: Smoking is strictly prohibited there. You mustn’t smoke and you mustn’t cut classes otherwise  you will be dismissed.
Steve: And do we have to bring books there?
David: No, you don’t have to bring them because there is a library there but you can do that if you want.
