What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? For all x, x is a janitor or x will not sleep. There is at least one x for which x will sleep or x is not a janitor.
For all x, if x sleeps, then x is a janitor. There is at least one x for which if x were a janitor, then x is sleeping.
