Consider the following premises. forall x_5: ~T_4(x_5) or P(x_5). forall x_5: ~Q_3(x_5) or W(x_5). forall x_5: ~W(x_5) or U_2(x_5). forall x_5: Q_3(x_5). Can we infer forall x_5: P(x_5) or U_2(x_5) from them?
 From forall x_5: Q_3(x_5) we can infer forall x_5: Q_3(x_5) or T_4(x_5). From forall x_5: Q_3(x_5) or T_4(x_5), forall x_5: ~Q_3(x_5) or W(x_5) we can infer forall x_5: T_4(x_5) or W(x_5). From forall x_5: T_4(x_5) or W(x_5), forall x_5: ~T_4(x_5) or P(x_5) we can infer forall x_5: W(x_5) or P(x_5). Finally, from forall x_5: W(x_5) or P(x_5), forall x_5: ~W(x_5) or U_2(x_5) we can infer forall x_5: P(x_5) or U_2(x_5). Therefore, the answer is yes.
