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: t -> q_16. ~p_16. q. p_16 <-> q_16.
~p_16 and q can be inferred via the conjunction rule. q and ~p_16 can be inferred via the conjunction rule. p_16 -> q_16 can be inferred via the biconditional elimination rule. q_16 -> p_16 can be inferred via the biconditional elimination rule. ~q_16 can be inferred via the biconditional elimination rule.
