What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Name the inference rule being used: forall z_3: T_3(z_3) <-> S(z_3). p_6 -> q. p_6 or T_3(j). q -> S(j).
p_6 -> S(j) can be inferred via the transitivity rule. R_1(j) -> p_6 can be inferred via the rewriting rule. forall z_3: T_3(z_3) -> S(z_3) can be inferred via the universal biconditional elimination rule. forall z_3: S(z_3) -> T_3(z_3) can be inferred via the universal biconditional elimination rule.
