Consider the following premises. For all x_10, x_10 is not an astronaut. For all x_10, x_10 is a writer or x_10 will listen to a song. For all x_10, x_10 is an astronaut or x_10 is a janitor. For all x_10, if x_10 listens to a song, then x_10 is making tea. For all x_10, x_10 will make tea or x_10 is not a writer. Can we infer the following from them? There is at least one x_10 for which either x_10 will make tea or x_10 is a janitor are not true.
 From the fact that for all x_10, x_10 is an astronaut or x_10 is a janitor, and that for all x_10, x_10 is not an astronaut we can infer that for all x_10, x_10 is a janitor. From the fact that for all x_10, x_10 will make tea or x_10 is not a writer we can infer that for all x_10, if x_10 were a writer, then x_10 is making tea. From the fact that for all x_10, if x_10 were a writer, then x_10 is making tea, that for all x_10, if x_10 listens to a song, then x_10 is making tea, and that for all x_10, x_10 is a writer or x_10 will listen to a song we can infer that for all x_10, x_10 will make tea. Finally, from the fact that for all x_10, x_10 will make tea, and that for all x_10, x_10 is a janitor we can infer that for all x_10, x_10 will make tea and x_10 is a janitor, which contradicts that There is at least one x_10 for which either x_10 will make tea or x_10 is a janitor are not true. Therefore, the answer is no.
