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_2, x_2 is not a musician. For all x_2, x_2 is a musician or x_2 will make tea. There is at least one x_2 for which x_2 is a server.
For all x_2, x_2 will make tea can be inferred via the universal disjunctive syllogism rule.
