Consider the following premises. There is at least one x_4 for which x_4 is not excited or x_4 will take a plane. For all x_4, if x_4 takes a plane, then x_4 is working. For all x_4, if x_4 were a carpenter, then x_4 is working. For all x_4, x_4 is excited. Can we infer the following from them? For all x_4, x_4 will not work.
 From the fact that for all x_4, x_4 is excited we can infer that for all x_4, x_4 is excited or x_4 is a carpenter. From the fact that for all x_4, x_4 is excited or x_4 is a carpenter, and that there is at least one x_4 for which x_4 is not excited or x_4 will take a plane we can infer that there is at least one x_4 for which x_4 is a carpenter or x_4 will take a plane. Finally, from the fact that for all x_4, if x_4 were a carpenter, then x_4 is working, that for all x_4, if x_4 takes a plane, then x_4 is working, and that there is at least one x_4 for which x_4 is a carpenter or x_4 will take a plane we can infer that there is at least one x_4 for which x_4 will work, which contradicts that For all x_4, x_4 will not work. Therefore, the answer is no.
