Consider the following premises. p_1 -> W(i_3). forall x_14: W(x_14) -> S_14(x_14). p_1. Can we infer ~S_14(i_3) from them? If possible, name the inference rules being used at each step.
 From forall x_14: W(x_14) -> S_14(x_14) we can infer W(i_3) -> S_14(i_3) via universal instantiation. From p_1 -> W(i_3), p_1 we can infer W(i_3) via modus ponens. Finally, from W(i_3) -> S_14(i_3), W(i_3) we can infer S_14(i_3) via modus ponens, which contradicts ~S_14(i_3). Therefore, the answer is no.
