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: James is a nurse or it is not late. If it is cloudy, then it is late. If James were a nurse, then it is cloudy.
If James were a nurse, then it is late can be inferred via the transitivity rule. If it is late, then James is a nurse can be inferred via the rewriting rule.
