Consider the following premises. For all x_9, x_9 will go running or x_9 will not take a plane. For all x_9, if x_9 were excited, then x_9 is driving a car. For all x_9, if x_9 drives a car, then x_9 is running. There is at least one x_9 for which x_9 is a poet or x_9 will take a plane. For all x_9, if x_9 were a poet, then x_9 is excited. Can we infer the following from them? For all x_9, x_9 will not go running.
 From the fact that for all x_9, if x_9 were excited, then x_9 is driving a car, and that for all x_9, if x_9 drives a car, then x_9 is running we can infer that for all x_9, if x_9 were excited, then x_9 is running. From the fact that for all x_9, if x_9 were a poet, then x_9 is excited, and that for all x_9, if x_9 were excited, then x_9 is running we can infer that for all x_9, if x_9 were a poet, then x_9 is running. From the fact that for all x_9, x_9 will go running or x_9 will not take a plane we can infer that for all x_9, if x_9 takes a plane, then x_9 is running. Finally, from the fact that for all x_9, if x_9 were a poet, then x_9 is running, that for all x_9, if x_9 takes a plane, then x_9 is running, and that there is at least one x_9 for which x_9 is a poet or x_9 will take a plane we can infer that there is at least one x_9 for which x_9 will go running, which contradicts that For all x_9, x_9 will not go running. Therefore, the answer is no.
