What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? There is at least one x_5 for which x_5 is poor or x_5 will take a plane. For all x_5, if x_5 were poor, then x_5 is playing squash. For all x_5, if x_5 plays squash, then x_5 is poor. For all x_5, if x_5 takes a plane, then x_5 is playing squash.
