Consider the following premises. Jennifer is rich. If it rains, then Jennifer is not rich. For all x_18, x_18 will read a book. Can we infer the following from them? If we can, name the inference rule being used: It is raining.
 From the fact that for all x_18, x_18 will read a book we can infer that Charles is reading a book via universal instantiation. Finally, from the fact that if it rains, then Jennifer is not rich, and that Jennifer is rich we can infer that it is not raining via modus tollens, which contradicts that It is raining. Therefore, the answer is no.
