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_16: P_16(x_16). forall x_16: P_14(x_16) and Q_14(x_16). forall x_16: P_16(x_16) -> Q_3(x_16). exists x_16: P_14(x_16) -> U(x_16).
forall x_16: Q_3(x_16) can be inferred via the universal modus ponens rule. forall x_16: P_14(x_16) can be inferred via the universal simplification rule. forall x_16: Q_14(x_16) can be inferred via the universal simplification rule.
