Consider the following premises. r_3 -> p_10. q_10 -> r_3. p_10 <-> q_10. ~p_10. Can we infer r_3 from them?
 From p_10 <-> q_10 we can infer p_10 -> q_10. From p_10 -> q_10, q_10 -> r_3 we can infer p_10 -> r_3. From r_3 -> p_10, p_10 -> r_3 we can infer r_3 <-> p_10. Finally, from r_3 <-> p_10, ~p_10 we can infer ~r_3, which contradicts r_3. Therefore, the answer is no.
