What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? exists x_8: P_8(x_8) or Q_8(x_8). forall x_8: Q_8(x_8) <-> Q_3(x_8). forall x_8: ~P_8(x_8).
exists x_8: Q_8(x_8). forall x_8: Q_8(x_8) -> Q_3(x_8). forall x_8: Q_3(x_8) -> Q_8(x_8).
