Consider the following premises. p_17 <-> Q(h). forall x: ~Q(x). p_5 and q_5. Can we infer p_5 and ~p_17 from them?
 From forall x: ~Q(x) we can infer ~Q(h). From p_17 <-> Q(h), ~Q(h) we can infer ~p_17. From p_5 and q_5 we can infer p_5. Finally, from p_5, ~p_17 we can infer p_5 and ~p_17. Therefore, the answer is yes.
