What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall y_1: R_3(y_1) <-> Q(y_1). forall y_1: R(y_1) -> T(y_1). forall y_1: R_3(y_1) or R(y_1). forall y_1: T(y_1) -> Q(y_1).
forall y_1: R(y_1) -> Q(y_1). forall y_1: R_3(y_1) -> Q(y_1). forall y_1: Q(y_1) -> R_3(y_1).
