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: forall y: P_10(y) -> S_3(y). forall y: P_10(y) or ~S_3(y). P_10(a_10).
exists x: P_10(x) can be inferred via the existential generalization rule. forall y: S_3(y) -> P_10(y) can be inferred via the universal rewriting rule.
