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 Joseph were a soldier, then it is late. If it is late, then Linda is driving a car. Joseph is not a soldier. If Linda drives a car, then Joseph is a soldier.
Linda is not driving a car can be inferred via the modus tollens rule. If Joseph were a soldier, then Linda is driving a car can be inferred via the transitivity rule. If it is late, then Joseph is a soldier can be inferred via the transitivity rule. If Linda drives a car, then it is late can be inferred via the transitivity rule.
