Consider the following premises. If James goes running, then Patricia is sleeping. If James were an artist, then James is running. For all x_19, x_19 will not sleep. Karen is curious. Can we infer the following from them? If we can, name the inference rule being used: James is an artist.
 From the fact that for all x_19, x_19 will not sleep we can infer that Patricia is not sleeping via universal instantiation. From the fact that if James goes running, then Patricia is sleeping, and that Patricia is not sleeping we can infer that James is not running via modus tollens. Finally, from the fact that if James were an artist, then James is running, and that James is not running we can infer that James is not an artist via modus tollens, which contradicts that James is an artist. Therefore, the answer is no.
