Consider the following premises. For all x_8, if x_8 were a server, then x_8 is cooking. For all x_8, x_8 is a server. For all x_8, x_8 is an electrician. For all x_8, if x_8 cooks, then x_8 is excited. Can we infer the following from them? If we can, name the inference rule being used: James is not excited.
 From the fact that for all x_8, if x_8 were a server, then x_8 is cooking, and that for all x_8, x_8 is a server we can infer that for all x_8, x_8 will cook via universal modus ponens. Finally, from the fact that for all x_8, if x_8 cooks, then x_8 is excited, and that for all x_8, x_8 will cook we can infer that for all x_8, x_8 is excited via universal modus ponens, which contradicts that James is not excited. Therefore, the answer is no.
