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: There is at least one y for which y is a bartender or y will not play a game. For all y, if y were a bartender, then y is playing a game. For all y, y is not a bartender.
There is at least one y for which if y plays a game, then y is a bartender can be inferred via the existential rewriting rule.
