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: Jennifer is not playing a game. If Thomas takes a plane, then Jennifer is playing a game. If Jennifer plays a game, then it is windy. If it is windy, then Thomas is taking a plane.
Thomas is not taking a plane can be inferred via the modus tollens rule. If Thomas takes a plane, then it is windy can be inferred via the transitivity rule. If Jennifer plays a game, then Thomas is taking a plane can be inferred via the transitivity rule. If it is windy, then Jennifer is playing a game can be inferred via the transitivity rule.
