Consider the following premises. ~p_9. p_9 or ~q_9. q_9 or ~p_9. Can we infer ~q_9 from them?
 From p_9 or ~q_9 we can infer q_9 -> p_9. From q_9 or ~p_9 we can infer p_9 -> q_9. From q_9 -> p_9, p_9 -> q_9 we can infer q_9 <-> p_9. Finally, from q_9 <-> p_9, ~p_9 we can infer ~q_9. Therefore, the answer is yes.
