Consider the following premises. S_10(a_10) -> s. forall x_10: R_10(x_10) -> S_10(x_10). p_1 -> R_10(a_10). Can we infer p_1 -> s 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 p_1 -> R_10(a_10), R_10(a_10) -> S_10(a_10) we can infer p_1 -> S_10(a_10) via transitivity. Finally, from p_1 -> S_10(a_10), S_10(a_10) -> s we can infer p_1 -> s via transitivity. Therefore, the answer is yes.
