Consider the following premises. q_1 -> u_1. S_10(a_10) -> q_1. forall x_10: R_10(x_10) -> S_10(x_10). Can we infer R_10(a_10) -> u_1 from them? If possible, name the inference rules being used at each step.
 From forall x_10: R_10(x_10) -> S_10(x_10) we can infer R_10(a_10) -> S_10(a_10) via universal instantiation. From S_10(a_10) -> q_1, q_1 -> u_1 we can infer S_10(a_10) -> u_1 via transitivity. Finally, from R_10(a_10) -> S_10(a_10), S_10(a_10) -> u_1 we can infer R_10(a_10) -> u_1 via transitivity. Therefore, the answer is yes.
