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: q -> w_4. ~p_10. p_10 <-> q. w_4 -> w_3. w_3 -> q.
q -> w_3 can be inferred via the transitivity rule. w_4 -> q can be inferred via the transitivity rule. w_3 -> w_4 can be inferred via the transitivity rule. p_10 -> q can be inferred via the biconditional elimination rule. q -> p_10 can be inferred via the biconditional elimination rule. ~q can be inferred via the biconditional elimination rule.
