Consider the following premises. p. forall x_11: R_11(x_11) and S_11(x_11). Can we infer p and R_11(a_11) from them?
 From forall x_11: R_11(x_11) and S_11(x_11) we can infer R_11(a_11) and S_11(a_11). From R_11(a_11) and S_11(a_11) we can infer R_11(a_11). Finally, from p, R_11(a_11) we can infer p and R_11(a_11). Therefore, the answer is yes.
