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: If Robert plays a game, then Thomas is not reading a book. For all x_17, x_17 will not climb a mountain. For all x_17, x_17 is not bored. For all x_17, x_17 will climb a mountain or x_17 is bored.
Since the premises are contradictory, we can infer anything from them.
