Consider the following premises. forall x_14: R_14(x_14) -> S_14(x_14). R_14(a_14) and s_3. Can we infer S_14(a_14) from them? If possible, name the inference rules being used at each step.
 From forall x_14: R_14(x_14) -> S_14(x_14) we can infer R_14(a_14) -> S_14(a_14) via universal instantiation. From R_14(a_14) and s_3 we can infer R_14(a_14) via simplification. Finally, from R_14(a_14) -> S_14(a_14), R_14(a_14) we can infer S_14(a_14) via modus ponens. Therefore, the answer is yes.
