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_16. p_16 or q_16. w <-> p. w -> ~r_16. ~p_16 or r_16.
q_16 or r_16 can be inferred via the resolution rule. w -> p can be inferred via the biconditional elimination rule. p -> w can be inferred via the biconditional elimination rule.
