What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Name the inference rule being used: There is at least one x_5 for which x_5 will read a book. For all x_5, if x_5 reads a book, then x_5 is not a soldier. For all x_5, x_5 is a soldier.
Since the premises are contradictory, we can infer anything from them.
