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: It is cloudy or James is not fast. If it is cloudy, then Jessica is curious. Jessica is not curious.
It is not cloudy can be inferred via the modus tollens rule. If James were fast, then it is cloudy can be inferred via the rewriting rule.
