Consider the following premises. For all x_9, x_9 is a carpenter or x_9 is not an astronaut. For all x_9, if x_9 drives a car, then x_9 is an astronaut. For all x_9, if x_9 were a carpenter, then x_9 is driving a car. Can we infer the following from them? If we can, name the inference rule being used: The fact that Joseph were a carpenter does not imply that Joseph is driving a car.
That contradicts the premises. Therefore the answer is no.
