Consider the following premises. R_10(a_10) or q. S_10(a_10) or ~q. forall x_10: R_10(x_10) -> S_10(x_10). Can we infer S_10(a_10) from them? If possible, name the inference rules being used at each step.
 From forall x_10: R_10(x_10) -> S_10(x_10) we can infer R_10(a_10) -> S_10(a_10) via universal instantiation. From S_10(a_10) or ~q we can infer q -> S_10(a_10) via rewriting. Finally, from R_10(a_10) -> S_10(a_10), q -> S_10(a_10), R_10(a_10) or q we can infer S_10(a_10) via disjunction elimination. Therefore, the answer is yes.
