What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? For all x_8, x_8 is curious. For all x_8, if x_8 plays squash, then x_8 is a soldier. For all x_8, x_8 will play squash. For all x_8, x_8 is not a soldier.
Since the premises are contradictory, we can infer anything from them.
