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_16 for which x_16 will read a book. For all x_16, if x_16 were a police officer, then x_16 is not reading a book. For all x_16, x_16 is curious if and only if x_16 will play squash. For all x_16, if x_16 were curious, then x_16 is a police officer.
