What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? T_4(j) <-> q_4. forall x: ~R_4(x). forall x: T_4(x) <-> R_4(x).
T_4(j) -> q_4. q_4 -> T_4(j). forall x: T_4(x) -> R_4(x). forall x: R_4(x) -> T_4(x). forall x: ~T_4(x).
