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_7: P_7(x_7). forall x_7: P_7(x_7) -> Q(x_7). forall x: Q(x) -> T_4(x).
forall x_7: Q(x_7) can be inferred via the universal modus ponens rule.
