Consider the following premises. For all x_26, if x_26 were a carpenter, then x_26 is a soldier. For all x_26, x_26 will work or x_26 is an astronaut. For all x_26, if x_26 were an astronaut, then x_26 is a carpenter. Sarah is a server and Susan is listening to a song. For all x_26, if x_26 works, then x_26 is a carpenter. Can we infer the following from them? Sarah is not a server.
 From the fact that for all x_26, if x_26 works, then x_26 is a carpenter, that for all x_26, if x_26 were an astronaut, then x_26 is a carpenter, and that for all x_26, x_26 will work or x_26 is an astronaut we can infer that for all x_26, x_26 is a carpenter. Finally, from the fact that Sarah is a server and Susan is listening to a song we can infer that Sarah is a server, which contradicts that Sarah is not a server. Therefore, the answer is no.
