Consider the following premises. forall x: R_3(x) and Q(x). Can we infer R_3(j_1) or q from them? If possible, name the inference rules being used at each step.
 From forall x: R_3(x) and Q(x) we can infer R_3(j_1) and Q(j_1) via universal instantiation. From R_3(j_1) and Q(j_1) we can infer R_3(j_1) via simplification. Finally, from R_3(j_1) we can infer R_3(j_1) or q via addition. Therefore, the answer is yes.
