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_14, x_14 is a server or x_14 is a musician. Joseph is not a musician. For all x_14, x_14 is not a server or x_14 will sleep.
