Consider the following premises. For all x_9, x_9 is a bartender. For all x_9, x_9 will not climb a mountain. For all x_9, if x_9 drives a car, then x_9 is running. For all x_9, x_9 will climb a mountain or x_9 is a taxi driver. For all x_9, if x_9 were a bartender, then x_9 is running. Can we infer the following from them? There is at least one x_9 for which either x_9 will go running or x_9 is a taxi driver are not true.
 From the fact that for all x_9, x_9 is a bartender we can infer that for all x_9, x_9 is a bartender or x_9 will drive a car. From the fact that for all x_9, if x_9 were a bartender, then x_9 is running, that for all x_9, if x_9 drives a car, then x_9 is running, and that for all x_9, x_9 is a bartender or x_9 will drive a car we can infer that for all x_9, x_9 will go running. From the fact that for all x_9, x_9 will climb a mountain or x_9 is a taxi driver, and that for all x_9, x_9 will not climb a mountain we can infer that for all x_9, x_9 is a taxi driver. Finally, from the fact that for all x_9, x_9 will go running, and that for all x_9, x_9 is a taxi driver we can infer that for all x_9, x_9 will go running and x_9 is a taxi driver, which contradicts that There is at least one x_9 for which either x_9 will go running or x_9 is a taxi driver are not true. Therefore, the answer is no.
