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_7, if x_7 plays a game, then x_7 is an artist. For all x_7, x_7 will not cook or x_7 is a lawyer. For all x_7, x_7 will cook or x_7 will play a game. For all x_7, if x_7 were a lawyer, then x_7 is an artist.
For all x_7, x_7 will play a game or x_7 is a lawyer can be inferred via the universal resolution rule.
