Consider the following premises. forall x_9: Q_9(x_9) -> R_7(x_9). forall x_9: R_9(x_9) -> R_7(x_9). forall x_9: P_9(x_9) or Q_9(x_9). forall x_9: ~P_9(x_9) or R_9(x_9). forall x_9: U(x_9). Can we infer R_7(g) from them?
 From forall x_9: P_9(x_9) or Q_9(x_9), forall x_9: ~P_9(x_9) or R_9(x_9) we can infer forall x_9: Q_9(x_9) or R_9(x_9). From forall x_9: Q_9(x_9) -> R_7(x_9), forall x_9: R_9(x_9) -> R_7(x_9), forall x_9: Q_9(x_9) or R_9(x_9) we can infer forall x_9: R_7(x_9). From forall x_9: U(x_9), forall x_9: R_7(x_9) we can infer forall x_9: U(x_9) and R_7(x_9). From forall x_9: U(x_9) and R_7(x_9) we can infer U(g) and R_7(g). Finally, from U(g) and R_7(g) we can infer R_7(g). Therefore, the answer is yes.
