Consider the following premises. There is at least one x_9 for which x_9 is a writer. For all x_9, if x_9 drives a car, then x_9 is a cashier. For all x_9, if x_9 were curious, then x_9 is driving a car. For all x_9, if x_9 makes tea, then x_9 is driving a car. For all x_9, x_9 will make tea. Can we infer the following from them? For all x_9, either x_9 is a cashier or x_9 is a writer are not true.
 From the fact that for all x_9, x_9 will make tea we can infer that for all x_9, x_9 will make tea or x_9 is curious. From the fact that for all x_9, if x_9 makes tea, then x_9 is driving a car, that for all x_9, if x_9 were curious, then x_9 is driving a car, and that for all x_9, x_9 will make tea or x_9 is curious we can infer that for all x_9, x_9 will drive a car. From the fact that for all x_9, if x_9 drives a car, then x_9 is a cashier, and that for all x_9, x_9 will drive a car we can infer that for all x_9, x_9 is a cashier. Finally, from the fact that for all x_9, x_9 is a cashier, and that there is at least one x_9 for which x_9 is a writer we can infer that some cashiers are writers, which contradicts that For all x_9, either x_9 is a cashier or x_9 is a writer are not true. Therefore, the answer is no.
