What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? For all z_3, if z_3 were rich, then z_3 is a janitor. For all z_3, if z_3 were a server, then z_3 is sleeping. There is at least one z_3 for which if z_3 sleeps, then z_3 is rich.
