Consider the following premises. There is at least one x_6 for which if x_6 makes tea, then x_6 is a lawyer. For all x_6, if x_6 were an astronaut, then x_6 is working. For all x_6, if x_6 were a lawyer, then x_6 is an astronaut. For all x_6, x_6 will make tea. Can we infer the following from them? For all x_6, x_6 will not work.
 From the fact that there is at least one x_6 for which if x_6 makes tea, then x_6 is a lawyer, and that for all x_6, if x_6 were a lawyer, then x_6 is an astronaut we can infer that there is at least one x_6 for which if x_6 makes tea, then x_6 is an astronaut. From the fact that there is at least one x_6 for which if x_6 makes tea, then x_6 is an astronaut, and that for all x_6, if x_6 were an astronaut, then x_6 is working we can infer that there is at least one x_6 for which if x_6 makes tea, then x_6 is working. Finally, from the fact that there is at least one x_6 for which if x_6 makes tea, then x_6 is working, and that for all x_6, x_6 will make tea we can infer that there is at least one x_6 for which x_6 will work, which contradicts that For all x_6, x_6 will not work. Therefore, the answer is no.
