Emily, Marc, and Thomas meet at a party to which novelists and poets have been invited. Every attendee at the party is either a novelist or a poet (but not both).
Every poet knows all the other poets, but every novelist does not know any of the other attendees, whether they are poets or novelists.
What do Emily, Marc, and Thomas know about each other's professions? Provide an Aumann model of incomplete information that describes this situation (there are several ways to do so).
