What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_1: R_1(x_1). forall x_1: Q_1(x_1). exists x_1: R_1(x_1) -> W_3(x_1).
exists x_1: W_3(x_1). forall x_1: R_1(x_1) and Q_1(x_1). forall x_1: Q_1(x_1) and R_1(x_1).
