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_25: W(x_25). forall x_25: W(x_25) <-> T(x_25). forall x_18: P_18(x_18).
forall x_25: W(x_25) -> T(x_25) can be inferred via the universal biconditional elimination rule. forall x_25: T(x_25) -> W(x_25) can be inferred via the universal biconditional elimination rule.
