What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? exists x_7: Q_4(x_7) -> W_3(x_7). forall x_7: Q_4(x_7) -> Q_7(x_7). forall x_7: ~Q_7(x_7). forall x_7: W(x_7) -> Q_4(x_7). forall x_7: W_3(x_7) -> W(x_7).
forall x_7: ~Q_4(x_7). forall x_7: W(x_7) -> Q_7(x_7). forall x_7: W_3(x_7) -> Q_4(x_7). exists x_7: Q_4(x_7) -> W(x_7). exists x_7: W(x_7) -> W_3(x_7).
