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_13(x_16) or P(x_16). forall x_16: P_16(x_16). exists x_16: R(x_16). forall x_16: P_16(x_16) -> Q_16(x_16). forall x_16: ~P_13(x_16).
forall x_16: Q_16(x_16). forall x_16: P(x_16). exists x_16: R(x_16) and P_16(x_16). exists x_16: P_16(x_16) and R(x_16).
