What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? exists x_8: Q(x_8). forall x_8: P_5(x_8) -> P_8(x_8). forall x_8: P_8(x_8) or ~Q_8(x_8). forall x_8: P_5(x_8).
forall x_8: P_8(x_8). exists x_8: Q(x_8) and P_5(x_8). exists x_8: P_5(x_8) and Q(x_8). forall x_8: Q_8(x_8) -> P_8(x_8).
