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_3 for which x_3 will read a book. For all x_3, if x_3 were excited, then x_3 is poor. For all x_3, x_3 is excited if and only if x_3 will read a book.
For all x_3, if x_3 were excited, then x_3 is reading a book. For all x_3, if x_3 reads a book, then x_3 is excited.
