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. ~s. p_16 or t_2. ~p_16 or p_2. t_2 <-> s.
p and ~s can be inferred via the conjunction rule. ~s and p can be inferred via the conjunction rule. t_2 or p_2 can be inferred via the resolution rule. t_2 -> s can be inferred via the biconditional elimination rule. s -> t_2 can be inferred via the biconditional elimination rule. ~t_2 can be inferred via the biconditional elimination rule.
