Consider the following premises. For all x_9, x_9 will go running or x_9 is a nurse. For all x_9, if x_9 were an artist, then x_9 is a poet. For all x_9, x_9 is an artist. For all x_9, if x_9 were a poet, then x_9 is an astronaut. For all x_9, if x_9 goes running, then x_9 is drinking water. For all x_9, if x_9 were a nurse, then x_9 is drinking water. Can we infer the following from them? There is at least one x_9 for which either x_9 is an astronaut or x_9 will drink water are not true.
 From the fact that for all x_9, if x_9 were an artist, then x_9 is a poet, and that for all x_9, if x_9 were a poet, then x_9 is an astronaut we can infer that for all x_9, if x_9 were an artist, then x_9 is an astronaut. From the fact that for all x_9, if x_9 goes running, then x_9 is drinking water, that for all x_9, if x_9 were a nurse, then x_9 is drinking water, and that for all x_9, x_9 will go running or x_9 is a nurse we can infer that for all x_9, x_9 will drink water. From the fact that for all x_9, if x_9 were an artist, then x_9 is an astronaut, and that for all x_9, x_9 is an artist we can infer that for all x_9, x_9 is an astronaut. Finally, from the fact that for all x_9, x_9 is an astronaut, and that for all x_9, x_9 will drink water we can infer that for all x_9, x_9 is an astronaut and x_9 will drink water, which contradicts that There is at least one x_9 for which either x_9 is an astronaut or x_9 will drink water are not true. Therefore, the answer is no.
