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: p_3 <-> q_3. q_3 or p_1. ~p_3.
p_3 -> q_3 can be inferred via the biconditional elimination rule. q_3 -> p_3 can be inferred via the biconditional elimination rule. ~q_3 can be inferred via the biconditional elimination rule.
