Consider the following premises. James is taking a plane. Charles is not an electrician. If Barbara were an artist, then Charles is an electrician. If Jennifer were a bartender, then Barbara is an artist. Can we infer the following from them? If we can, name the inference rule being used: Jennifer is a bartender.
 From the fact that if Barbara were an artist, then Charles is an electrician, and that Charles is not an electrician we can infer that Barbara is not an artist via modus tollens. Finally, from the fact that if Jennifer were a bartender, then Barbara is an artist, and that Barbara is not an artist we can infer that Jennifer is not a bartender via modus tollens, which contradicts that Jennifer is a bartender. Therefore, the answer is no.
