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_10 and q_10. r_4 <-> p_2. p_2 -> ~p_10.
p_10 can be inferred via the simplification rule. q_10 can be inferred via the simplification rule. r_4 -> p_2 can be inferred via the biconditional elimination rule. p_2 -> r_4 can be inferred via the biconditional elimination rule.
