Consider the following premises. For all x_19, x_19 will drive a car if and only if x_19 will take a plane. There is at least one x_19 for which x_19 is a cashier if and only if x_19 will read a book. For all x_19, x_19 will not read a book. For all x_19, x_19 will drive a car if and only if x_19 is a cashier. Can we infer the following from them? For all x_19, x_19 will take a plane.
 From the fact that there is at least one x_19 for which x_19 is a cashier if and only if x_19 will read a book, and that for all x_19, x_19 will not read a book we can infer that there is at least one x_19 for which x_19 is not a cashier. From the fact that for all x_19, x_19 will drive a car if and only if x_19 is a cashier we can infer that for all x_19, if x_19 drives a car, then x_19 is a cashier. From the fact that for all x_19, if x_19 drives a car, then x_19 is a cashier, and that there is at least one x_19 for which x_19 is not a cashier we can infer that there is at least one x_19 for which x_19 will not drive a car. Finally, from the fact that for all x_19, x_19 will drive a car if and only if x_19 will take a plane, and that there is at least one x_19 for which x_19 will not drive a car we can infer that there is at least one x_19 for which x_19 will not take a plane, which contradicts that For all x_19, x_19 will take a plane. Therefore, the answer is no.
