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: There is at least one x_14 for which x_14 is a musician or x_14 is a server. For all x_14, if x_14 were a poet, then x_14 is excited. For all x_14, x_14 is not a musician or x_14 is a poet. For all x_14, x_14 is excited or x_14 is not a server.
There is at least one x_14 for which x_14 is a server or x_14 is a poet can be inferred via the existential resolution rule. For all x_14, if x_14 were a server, then x_14 is excited can be inferred via the universal rewriting rule.
