What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? t_1 <-> w_3. t_1 <-> S_2(a). ~w_3. forall x_7: S_2(x_7) <-> S_7(x_7).
t_1 -> w_3. t_1 -> S_2(a). w_3 -> t_1. S_2(a) -> t_1. ~t_1. forall x_7: S_2(x_7) -> S_7(x_7). forall x_7: S_7(x_7) -> S_2(x_7).
