Consider the following premises. For all y, y is excited or y is not a server. For all y, if y makes tea, then y is a server. For all y, y will make tea if and only if y is a soldier. Can we infer the following from them? There is at least one y for which the fact that y were a soldier does not imply that y is excited.
 From the fact that for all y, y will make tea if and only if y is a soldier we can infer that for all y, if y were a soldier, then y is making tea. From the fact that for all y, y is excited or y is not a server we can infer that for all y, if y were a server, then y is excited. From the fact that for all y, if y makes tea, then y is a server, and that for all y, if y were a server, then y is excited we can infer that for all y, if y makes tea, then y is excited. Finally, from the fact that for all y, if y were a soldier, then y is making tea, and that for all y, if y makes tea, then y is excited we can infer that for all y, if y were a soldier, then y is excited, which contradicts that There is at least one y for which the fact that y were a soldier does not imply that y is excited. Therefore, the answer is no.
