Consider the following premises. For all x_6, if x_6 plays squash, then x_6 is playing a game. For all x_6, x_6 will play squash or x_6 will not go running. There is at least one x_6 for which x_6 will not play a game. Can we infer the following from them? For all x_6, x_6 will go running.
 From the fact that for all x_6, if x_6 plays squash, then x_6 is playing a game, and that there is at least one x_6 for which x_6 will not play a game we can infer that there is at least one x_6 for which x_6 will not play squash. From the fact that for all x_6, x_6 will play squash or x_6 will not go running we can infer that for all x_6, if x_6 goes running, then x_6 is playing squash. Finally, from the fact that for all x_6, if x_6 goes running, then x_6 is playing squash, and that there is at least one x_6 for which x_6 will not play squash we can infer that there is at least one x_6 for which x_6 will not go running, which contradicts that For all x_6, x_6 will go running. Therefore, the answer is no.
