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