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: r_4 -> P_16(a_14). forall x_19: P_19(x_19). forall x_19: P_16(x_19) -> ~Q_19(x_19). forall x_19: P_19(x_19) -> Q_19(x_19). q.
forall x_19: Q_19(x_19) can be inferred via the universal modus ponens rule.
