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: forall y: Q_2(y) or ~W_3(y). forall y: ~P(y) or R(y). forall y: R(y) -> Q_2(y). exists y: R_2(y) -> W_3(y). forall y: P(y) or R_2(y).
forall y: R_2(y) or R(y) can be inferred via the universal resolution rule. forall y: W_3(y) -> Q_2(y) can be inferred via the universal rewriting rule.
