What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? exists x_12: Q(x_12) -> T(x_12). forall x_12: R(x_12) -> T(x_12). forall x_12: T(x_12) -> R(x_12). forall x_12: T(x_12) -> Q(x_12). forall x_12: R(x_12) or Q(x_12).
forall x_12: R(x_12) -> Q(x_12). exists x_12: Q(x_12) -> R(x_12). exists x_12: T(x_12). forall x_12: R(x_12) <-> T(x_12). forall x_12: T(x_12) <-> R(x_12). exists x_12: Q(x_12) <-> T(x_12). exists x_12: T(x_12) <-> Q(x_12).
