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: For all x_8, x_8 is not curious or x_8 will sleep. There is at least one x_8 for which x_8 is not fast or x_8 will drive a car. For all x_8, x_8 is fast and x_8 will play a game.
For all x_8, x_8 is fast can be inferred via the universal simplification rule. For all x_8, x_8 will play a game can be inferred via the universal simplification rule.
