What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Name the inference rule being used: For all x_10, if x_10 were a bartender, then x_10 is taking a plane. There is at least one x_10 for which if x_10 plays a game, then x_10 is taking a plane. For all x_10, x_10 is a bartender.
For all x_10, x_10 will take a plane can be inferred via the universal modus ponens rule.
