Consider the following premises. forall x_9: P_9(x_9). p_1. Can we infer p_1 and P_9(a_9) from them? If possible, name the inference rules being used at each step.
 From forall x_9: P_9(x_9) we can infer P_9(a_9) via universal instantiation. Finally, from p_1, P_9(a_9) we can infer p_1 and P_9(a_9) via conjunction. Therefore, the answer is yes.
