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_14. p_1. s <-> q_14.
~q_14 and p_1 can be inferred via the conjunction rule. p_1 and ~q_14 can be inferred via the conjunction rule. s -> q_14 can be inferred via the biconditional elimination rule. q_14 -> s can be inferred via the biconditional elimination rule. ~s can be inferred via the biconditional elimination rule.
