Consider the following premises. For all y, y is an astronaut. For all x_10, if x_10 sleeps, then x_10 is an astronaut. For all x_10, if x_10 were an astronaut, then x_10 is sleeping. Can we infer the following from them? Elisabeth is not sleeping.
 From the fact that for all y, y is an astronaut we can infer that Elisabeth is an astronaut. From the fact that for all x_10, if x_10 were an astronaut, then x_10 is sleeping, and that for all x_10, if x_10 sleeps, then x_10 is an astronaut we can infer that for all x_10, x_10 is an astronaut if and only if x_10 will sleep. From the fact that for all x_10, x_10 is an astronaut if and only if x_10 will sleep we can infer that for all x_10, if x_10 were an astronaut, then x_10 is sleeping. From the fact that for all x_10, if x_10 were an astronaut, then x_10 is sleeping we can infer that if Elisabeth were an astronaut, then Elisabeth is sleeping. Finally, from the fact that if Elisabeth were an astronaut, then Elisabeth is sleeping, and that Elisabeth is an astronaut we can infer that Elisabeth is sleeping, which contradicts that Elisabeth is not sleeping. Therefore, the answer is no.
