What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_13: Q_13(x_13) -> P_13(x_13). forall x_13: P_5(x_13) -> Q_13(x_13). forall x_13: P_13(x_13) -> Q_13(x_13). forall x_13: ~P_13(x_13). forall x_13: W_3(x_13) <-> P_5(x_13). exists x_13: U_3(x_13) <-> W_3(x_13).
forall x_13: ~Q_13(x_13). forall x_13: P_5(x_13) -> P_13(x_13). forall x_13: Q_13(x_13) <-> P_13(x_13). forall x_13: P_13(x_13) <-> Q_13(x_13). forall x_13: W_3(x_13) -> P_5(x_13). exists x_13: U_3(x_13) -> W_3(x_13). forall x_13: P_5(x_13) -> W_3(x_13). exists x_13: W_3(x_13) -> U_3(x_13).
