Consider the following premises. p_1 -> R_10(c). u or p_1. forall x_10: R_10(x_10) -> S_10(x_10). u -> S_10(c). Can we infer S_10(c) 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(c) -> S_10(c) via universal instantiation. From p_1 -> R_10(c), R_10(c) -> S_10(c) we can infer p_1 -> S_10(c) via transitivity. Finally, from u -> S_10(c), p_1 -> S_10(c), u or p_1 we can infer S_10(c) via disjunction elimination. Therefore, the answer is yes.
