Consider the following premises. For all x_9, x_9 will climb a mountain or x_9 is not an astronaut. There is at least one x_9 for which x_9 is an astronaut or x_9 will not climb a mountain. Can we infer the following from them? For all x_9, the fact that x_9 were an astronaut does not imply that x_9 is climbing a mountain.
 From the fact that there is at least one x_9 for which x_9 is an astronaut or x_9 will not climb a mountain we can infer that there is at least one x_9 for which if x_9 climbs a mountain, then x_9 is an astronaut. Finally, from the fact that for all x_9, x_9 will climb a mountain or x_9 is not an astronaut we can infer that for all x_9, if x_9 were an astronaut, then x_9 is climbing a mountain, which contradicts that For all x_9, the fact that x_9 were an astronaut does not imply that x_9 is climbing a mountain. Therefore, the answer is no.
