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 x_5: Q_3(x_5) -> S_5(x_5). forall x_3: U(x_3). forall x_3: U(x_3) -> Q_3(x_3).
forall x_3: Q_3(x_3) can be inferred via the universal modus ponens rule.
