## Questions:

What is the role of a conductor in an #$ClassicalMusicalPerformance?

- #$performedBy
- #$informationOrigin
- directingAgent

For the next bunch, when we say ``what is/are the role(s) of X in Y'', we mean tell us what are the most specific roles of X in Y. As a general rule, it is always a good idea to look at the generalizations and specializations of a predicate before using it in an assertion to be sure one is not being too specific or general. Hint: Many of the roles you will want to use are specializations of #$objectMoving.
