Consider the following premises. forall x_14: R_14(x_14) -> S_14(x_14). p. R_14(g) or u. u -> S_14(g). Can we infer p and S_14(g) 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(g) -> S_14(g) via universal instantiation. From R_14(g) -> S_14(g), u -> S_14(g), R_14(g) or u we can infer S_14(g) via disjunction elimination. Finally, from p, S_14(g) we can infer p and S_14(g) via conjunction. Therefore, the answer is yes.
