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 it rains, then James is a nurse. If it is sunny, then it is raining. For all x_10, if x_10 were a carpenter, then x_10 is a nurse. James is a carpenter or it is sunny.
If it is sunny, then James is a nurse can be inferred via the transitivity rule.
