Consider the following premises. For all x_8, x_8 will make tea. For all x_8, x_8 is happy. For all x_8, x_8 will go running and x_8 is an astronaut. Can we infer the following from them? There is at least one x_8 for which either x_8 will go running or x_8 is happy are not true.
 From the fact that for all x_8, x_8 will go running and x_8 is an astronaut we can infer that for all x_8, x_8 will go running. From the fact that for all x_8, x_8 is happy, and that for all x_8, x_8 will make tea we can infer that for all x_8, x_8 is happy and x_8 will make tea. From the fact that for all x_8, x_8 is happy and x_8 will make tea we can infer that for all x_8, x_8 is happy. Finally, from the fact that for all x_8, x_8 will go running, and that for all x_8, x_8 is happy we can infer that for all x_8, x_8 will go running and x_8 is happy, which contradicts that There is at least one x_8 for which either x_8 will go running or x_8 is happy are not true. Therefore, the answer is no.
