What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Name the inference rule being used: exists x_16: ~P_16(x_16) or R_16(x_16). forall x_16: P_16(x_16) or Q_16(x_16). forall x_16: Q_1(x_16) or ~R_16(x_16). forall x_16: Q_16(x_16) -> Q_1(x_16).
exists x_16: Q_16(x_16) or R_16(x_16) can be inferred via the existential resolution rule. forall x_16: R_16(x_16) -> Q_1(x_16) can be inferred via the universal rewriting rule.
