Consider the following premises. forall x_14: R_14(x_14) <-> S_14(x_14). ~S_14(a_14). R_14(a_14) or r. Can we infer q_1 or r 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) <-> S_14(a_14), ~S_14(a_14) we can infer ~R_14(a_14) via biconditional elimination. From ~R_14(a_14) we can infer ~R_14(a_14) or q_1 via addition. Finally, from ~R_14(a_14) or q_1, R_14(a_14) or r we can infer q_1 or r via resolution. Therefore, the answer is yes.
