Consider the following premises. For all x_6, if x_6 were rich, then x_6 is driving a car. For all x_6, x_6 will make tea or x_6 is a scientist. For all x_6, if x_6 were a scientist, then x_6 is rich. There is at least one x_6 for which if x_6 were a police officer, then x_6 is driving a car. For all x_6, x_6 will not make tea or x_6 is a police officer. Can we infer the following from them? 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 make tea or x_6 is a scientist, and that for all x_6, x_6 will not make tea or x_6 is a police officer we can infer that for all x_6, x_6 is a scientist or x_6 is a police officer. From the fact that for all x_6, if x_6 were a scientist, then x_6 is rich, and that for all x_6, if x_6 were rich, then x_6 is driving a car we can infer that for all x_6, if x_6 were a scientist, then x_6 is driving a car. Finally, from the fact that for all x_6, if x_6 were a scientist, then x_6 is driving a car, that there is at least one x_6 for which if x_6 were a police officer, then x_6 is driving a car, and that for all x_6, x_6 is a scientist or x_6 is a police officer we can infer that there is at least one x_6 for which x_6 will drive a car. Therefore, the answer is yes.
