Consider the following premises. p_14 or ~q_14. q_14 -> w. q_9. w -> ~q_9. p_14 -> q_14. Can we infer p_14 from them?
 From p_14 or ~q_14 we can infer q_14 -> p_14. From w -> ~q_9, q_9 we can infer ~w. From p_14 -> q_14, q_14 -> p_14 we can infer p_14 <-> q_14. From q_14 -> w, ~w we can infer ~q_14. Finally, from p_14 <-> q_14, ~q_14 we can infer ~p_14, which contradicts p_14. Therefore, the answer is no.
