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 y for which y is a nurse. For all y, y will go running if and only if y is a nurse. For all y, if y goes running, then y is playing a game.
For all y, if y goes running, then y is a nurse. For all y, if y were a nurse, then y is running.
