Consider the following premises. For all x_6, if x_6 drives a car, then x_6 is not reading a book. For all x_6, if x_6 were a lawyer, then x_6 is reading a book. For all x_6, x_6 will read a book or x_6 is not an electrician. For all x_6, x_6 is an electrician or x_6 is a lawyer. Can we infer the following from them? If we can, name the inference rule being used: There is at least one x_6 for which x_6 will drive a car.
 From the fact that for all x_6, x_6 will read a book or x_6 is not an electrician we can infer that for all x_6, if x_6 were an electrician, then x_6 is reading a book via universal rewriting. From the fact that for all x_6, if x_6 were an electrician, then x_6 is reading a book, that for all x_6, if x_6 were a lawyer, then x_6 is reading a book, and that for all x_6, x_6 is an electrician or x_6 is a lawyer we can infer that for all x_6, x_6 will read a book via universal disjunction elimination. Finally, from the fact that for all x_6, if x_6 drives a car, then x_6 is not reading a book, and that for all x_6, x_6 will read a book we can infer that for all x_6, x_6 will not drive a car via universal modus tollens, which contradicts that There is at least one x_6 for which x_6 will drive a car. Therefore, the answer is no.
