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_14 <-> q_14. p_14 -> r. s_3 <-> q_14. ~r.
~p_14 can be inferred via the modus tollens rule. p_14 -> q_14 can be inferred via the biconditional elimination rule. s_3 -> q_14 can be inferred via the biconditional elimination rule. q_14 -> p_14 can be inferred via the biconditional elimination rule. q_14 -> s_3 can be inferred via the biconditional elimination rule.
