Consider the following premises. R(a_18) -> q_1. forall x_22: Q_22(x_22) -> R(x_22). forall x_22: W_3(x_22) -> R(x_22). forall x_22: W_3(x_22) or Q_22(x_22). Can we infer q_1 or s_3 from them? If possible, name the inference rules being used at each step.
 From forall x_22: W_3(x_22) -> R(x_22), forall x_22: Q_22(x_22) -> R(x_22), forall x_22: W_3(x_22) or Q_22(x_22) we can infer forall x_22: R(x_22) via universal disjunction elimination. From forall x_22: R(x_22) we can infer R(a_18) via universal instantiation. From R(a_18) -> q_1, R(a_18) we can infer q_1 via modus ponens. Finally, from q_1 we can infer q_1 or s_3 via addition. Therefore, the answer is yes.
