What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall y_3: ~W_1(y_3) or Q_2(y_3). forall y_3: P(y_3). forall y_3: W_1(y_3) or R(y_3). forall y_3: Q_2(y_3) -> R_3(y_3). forall y_3: R(y_3) -> R_3(y_3).
forall y_3: R(y_3) or Q_2(y_3).
