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: exists x_5: T_1(x_5) -> T(x_5). forall x_5: W(x_5) <-> T(x_5). forall x_5: W(x_5).
forall x_5: W(x_5) -> T(x_5) can be inferred via the universal biconditional elimination rule. forall x_5: T(x_5) -> W(x_5) can be inferred via the universal biconditional elimination rule.
