What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? There is at least one x_11 for which if x_11 works, then x_11 is not excited. For all x_11, if x_11 reads a book, then x_11 is a soldier. For all x_11, x_11 will sleep if and only if x_11 is excited. For all x_11, x_11 will sleep or x_11 will read a book. For all x_11, if x_11 were a soldier, then x_11 is excited.
For all x_11, if x_11 reads a book, then x_11 is excited. For all x_11, if x_11 sleeps, then x_11 is excited. For all x_11, if x_11 were excited, then x_11 is sleeping.
