Consider the following premises. forall x_6: R_2(x_6) and Q_6(x_6). forall x_6: R(x_6). Can we infer R(g) from them? If possible, name the inference rules being used at each step.
 From forall x_6: R_2(x_6) and Q_6(x_6) we can infer forall x_6: R_2(x_6) via universal simplification. From forall x_6: R(x_6), forall x_6: R_2(x_6) we can infer forall x_6: R(x_6) and R_2(x_6) via universal conjunction. From forall x_6: R(x_6) and R_2(x_6) we can infer R(g) and R_2(g) via universal instantiation. Finally, from R(g) and R_2(g) we can infer R(g) via simplification. Therefore, the answer is yes.
