What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall y: Q(y) -> P_2(y). forall y: P_2(y) -> Q(y). forall y: T(y) -> P_2(y). forall y: P_2(y) -> T(y). forall y: ~Q(y).
forall y: ~P_2(y). forall y: Q(y) -> T(y). forall y: T(y) -> Q(y). forall y: Q(y) <-> P_2(y). forall y: P_2(y) <-> Q(y). forall y: T(y) <-> P_2(y). forall y: P_2(y) <-> T(y).
