Consider the following premises. For all x_6, x_6 is a janitor. There is at least one x_6 for which x_6 will drive a car or x_6 is not a janitor. For all x_6, if x_6 were rich, then x_6 is driving a car. Can we infer the following from them? If we can, name the inference rule being used: For all x_6, if x_6 were rich, then x_6 is driving a car.
That is one of the premises. Therefore, the answer is yes.
