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_8. p_8 <-> q_8. ~p_8 -> q.
p_8 -> q_8 can be inferred via the biconditional elimination rule. q_8 -> p_8 can be inferred via the biconditional elimination rule. ~p_8 can be inferred via the biconditional elimination rule.
