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: exists x_6: W(x_6) and S(x_6). forall x_6: P(x_6).
exists x_6: W(x_6) can be inferred via the existential simplification rule. exists x_6: S(x_6) can be inferred via the existential simplification rule.
