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: ~r_2. ~p_16. r_2 <-> w_3. p_16 <-> p_2.
~r_2 and ~p_16 can be inferred via the conjunction rule. ~p_16 and ~r_2 can be inferred via the conjunction rule. r_2 -> w_3 can be inferred via the biconditional elimination rule. p_16 -> p_2 can be inferred via the biconditional elimination rule. w_3 -> r_2 can be inferred via the biconditional elimination rule. p_2 -> p_16 can be inferred via the biconditional elimination rule. ~w_3 can be inferred via the biconditional elimination rule. ~p_2 can be inferred via the biconditional elimination rule.
