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 Jennifer listens to a song, then it is windy. Jessica is a mechanic. If Jessica were a mechanic, then Jennifer is listening to a song. If it is cold, then it is not windy.
Jennifer is listening to a song can be inferred via the modus ponens rule. If Jessica were a mechanic, then it is windy can be inferred via the transitivity rule.
