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_4. p_10 or p. ~p or p_3. ~p_10 or q_2. q_2 <-> q_4.
p or q_2 can be inferred via the resolution rule. q_2 -> q_4 can be inferred via the biconditional elimination rule. q_4 -> q_2 can be inferred via the biconditional elimination rule. ~q_2 can be inferred via the biconditional elimination rule.
