Consider the following premises. For all x_6, x_6 is not excited. For all x_6, x_6 will take a plane or x_6 is excited. For all x_6, x_6 will not take a plane or x_6 will cook. Can we infer the following from them? John is not cooking.
 From the fact that for all x_6, x_6 will take a plane or x_6 is excited, and that for all x_6, x_6 will not take a plane or x_6 will cook we can infer that for all x_6, x_6 is excited or x_6 will cook. Finally, from the fact that for all x_6, x_6 is excited or x_6 will cook, and that for all x_6, x_6 is not excited we can infer that for all x_6, x_6 will cook, which contradicts that John is not cooking. Therefore, the answer is no.
