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 Sarah drives a car, then it is cold. If Sarah works, then James is climbing a mountain. If James climbs a mountain, then it is cloudy. If it is cloudy, then Jessica is drinking water. If Jessica drinks water, then Sarah is driving a car.
If Sarah works, then it is cloudy can be inferred via the transitivity rule. If James climbs a mountain, then Jessica is drinking water can be inferred via the transitivity rule. If it is cloudy, then Sarah is driving a car can be inferred via the transitivity rule. If Jessica drinks water, then it is cold can be inferred via the transitivity rule.
