Consider the following premises. For all x_5, x_5 is not sad. For all x_5, if x_5 works, then x_5 is sad. For all x_5, x_5 will work or x_5 will not go running. Can we infer the following from them? For all x_5, x_5 will not go running.
 From the fact that for all x_5, if x_5 works, then x_5 is sad, and that for all x_5, x_5 is not sad we can infer that for all x_5, x_5 will not work. From the fact that for all x_5, x_5 will work or x_5 will not go running we can infer that for all x_5, if x_5 goes running, then x_5 is working. Finally, from the fact that for all x_5, if x_5 goes running, then x_5 is working, and that for all x_5, x_5 will not work we can infer that for all x_5, x_5 will not go running. Therefore, the answer is yes.
