Bonjour,

Réponse :

1. you're in a hospital. you mustn't shout.  ( interdiction )

2. after the party you'll all have to help me clean up. I can't do it alone.

a.has to. b. have to. c.must.  ( obligation )

3. Donald Can't see well. he has to wear glasses.

a.doesn't have to. b. have to. c. has to. 

4. Betty had to  buy an anti-virus program last week. A virus deleted all last files.  ( obligation dans le passé )

a. has to. b. must. c. had to.

5. you don't have to send invitations for the party. you can send emails to everybody. ( absence d'obligation )

a. mustn't. b.had to. c. don't have to. 

6. the students have to surf the the net to find the information they need for their projects.

a.has. b.have. c. must. 

.... Dans la phrase de départ, (the students ... to surf the the net to find the information they need for their projects. ) il y a "to", on est donc obligé de mettre 'have' car sujet pluriel et 'must' est toujours suivi d'une base verbale.
