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_16, if x_16 were an artist, then x_16 is playing tennis. Sarah is a server. For all x_16, if x_16 listens to a song, then x_16 is playing tennis. For all x_16, x_16 is an artist or x_16 will listen to a song. For all x_16, x_16 will drive a car.
For all x_16, x_16 will play tennis can be inferred via the universal disjunction elimination rule.
