Consider the following premises. For all x_3, x_3 will not play a game or x_3 is fast. For all x_3, if x_3 were sad, then x_3 is running. For all x_3, if x_3 were fast, then x_3 is sad. For all x_3, x_3 will play a game or x_3 will work. There is at least one x_3 for which if x_3 works, then x_3 is running. Can we infer the following from them? For all x_3, x_3 will not go running.
 From the fact that for all x_3, if x_3 were fast, then x_3 is sad, and that for all x_3, if x_3 were sad, then x_3 is running we can infer that for all x_3, if x_3 were fast, then x_3 is running. From the fact that for all x_3, x_3 will play a game or x_3 will work, and that for all x_3, x_3 will not play a game or x_3 is fast we can infer that for all x_3, x_3 will work or x_3 is fast. Finally, from the fact that there is at least one x_3 for which if x_3 works, then x_3 is running, that for all x_3, if x_3 were fast, then x_3 is running, and that for all x_3, x_3 will work or x_3 is fast we can infer that there is at least one x_3 for which x_3 will go running, which contradicts that For all x_3, x_3 will not go running. Therefore, the answer is no.
