What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? p_11 <-> w_2. S_7(a_7) -> p_11. ~w_2. forall x_7: R_7(x_7) <-> S_7(x_7).
p_11 -> w_2. w_2 -> p_11. ~p_11. forall x_7: R_7(x_7) -> S_7(x_7). forall x_7: S_7(x_7) -> R_7(x_7).
