What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? ~q. q <-> t_2. forall x_7: R_7(x_7) <-> S_7(x_7). S_7(j) <-> t_2.
q -> t_2. S_7(j) -> t_2. t_2 -> q. t_2 -> S_7(j). ~t_2. forall x_7: R_7(x_7) -> S_7(x_7). forall x_7: S_7(x_7) -> R_7(x_7).
