Consider the following premises. There is at least one x_6 for which x_6 is a soldier and x_6 is an astronaut. For all x_6, if x_6 plays squash, then x_6 is not a soldier. Can we infer the following from them? There is at least one x_6 for which x_6 will not play squash.
 From the fact that there is at least one x_6 for which x_6 is a soldier and x_6 is an astronaut we can infer that there is at least one x_6 for which x_6 is a soldier. Finally, from the fact that for all x_6, if x_6 plays squash, then x_6 is not a soldier, and that there is at least one x_6 for which x_6 is a soldier we can infer that there is at least one x_6 for which x_6 will not play squash. Therefore, the answer is yes.
