Consider the following premises. For all x_8, if x_8 were a sailor, then x_8 is making tea. For all x_8, x_8 is an astronaut if and only if x_8 will make tea. There is at least one x_8 for which if x_8 were a police officer, then x_8 is a sailor. For all x_8, x_8 is a police officer or x_8 is an astronaut. Can we infer the following from them? For all x_8, x_8 will not make tea.
 From the fact that for all x_8, x_8 is an astronaut if and only if x_8 will make tea we can infer that for all x_8, if x_8 were an astronaut, then x_8 is making tea. From the fact that there is at least one x_8 for which if x_8 were a police officer, then x_8 is a sailor, and that for all x_8, if x_8 were a sailor, then x_8 is making tea we can infer that there is at least one x_8 for which if x_8 were a police officer, then x_8 is making tea. Finally, from the fact that there is at least one x_8 for which if x_8 were a police officer, then x_8 is making tea, that for all x_8, if x_8 were an astronaut, then x_8 is making tea, and that for all x_8, x_8 is a police officer or x_8 is an astronaut we can infer that there is at least one x_8 for which x_8 will make tea, which contradicts that For all x_8, x_8 will not make tea. Therefore, the answer is no.
