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: Thomas is an electrician or Susan is listening to a song. If it is late, then Jessica is bored. If Susan listens to a song, then Robert is an artist. Thomas is not an electrician or it is late. If Robert were an artist, then Jessica is bored.
If Susan listens to a song, then Jessica is bored can be inferred via the transitivity rule. Susan is listening to a song or it is late can be inferred via the resolution rule.
