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_15, if x_15 plays a game, then x_15 is a lawyer. For all x_15, if x_15 were bored, then x_15 is not a lawyer. For all x_15, x_15 will not read a book. For all x_15, x_15 will read a book or x_15 will play a game. Patricia is bored or Robert is rich.
For all x_15, x_15 will play a game can be inferred via the universal disjunctive syllogism rule.
