Consider the following premises. forall x_9: P_9(x_9) or Q_9(x_9). forall x_9: ~P_9(x_9). forall x_9: P_6(x_9) and Q_6(x_9). Can we infer ~P_6(g) from them?
 From forall x_9: P_9(x_9) or Q_9(x_9), forall x_9: ~P_9(x_9) we can infer forall x_9: Q_9(x_9). Finally, from forall x_9: P_6(x_9) and Q_6(x_9) we can infer forall x_9: P_6(x_9), which contradicts ~P_6(g). Therefore, the answer is no.
