Consider the following premises. forall x_3: S(x_3) and T_3(x_3). s. Can we infer S(a_9) and s from them?
 From forall x_3: S(x_3) and T_3(x_3) we can infer forall x_3: S(x_3). From forall x_3: S(x_3) we can infer S(a_9). Finally, from S(a_9), s we can infer S(a_9) and s. Therefore, the answer is yes.
