What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_1: T(x_1) or ~W_1(x_1). forall x_1: W_1(x_1) <-> R(x_1). forall x_1: R(x_1) -> W_1(x_1).
forall x_1: W_1(x_1) -> T(x_1). forall x_1: W_1(x_1) -> R(x_1). forall x_1: R(x_1) -> W_1(x_1).
