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 y, if y cooks, then y is playing a game. For all y, if y drinks water, then y is cooking. For all y, y will read a book or y will not play a game.
For all y, if y drinks water, then y is playing a game can be inferred via the universal transitivity rule. For all y, if y plays a game, then y is reading a book can be inferred via the universal rewriting rule.
