What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_16: P_16(x_16) or ~T_3(x_16). T_3(f). forall x_16: P_16(x_16) <-> Q_16(x_16).
exists x: T_3(x). forall x_16: T_3(x_16) -> P_16(x_16). forall x_16: P_16(x_16) -> Q_16(x_16). forall x_16: Q_16(x_16) -> P_16(x_16).
