Consider the following premises. exists x_10: R_4(x_10). forall x_10: Q_10(x_10). Can we infer forall x_10: ~(R_4(x_10) or Q(x_10)) from them?
 From exists x_10: R_4(x_10), forall x_10: Q_10(x_10) we can infer exists x_10: R_4(x_10) and Q_10(x_10). From exists x_10: R_4(x_10) and Q_10(x_10) we can infer exists x_10: R_4(x_10). Finally, from exists x_10: R_4(x_10) we can infer exists x_10: R_4(x_10) or Q(x_10), which contradicts forall x_10: ~(R_4(x_10) or Q(x_10)). Therefore, the answer is no.
