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 Jennifer were a carpenter, then Susan is drinking water. For all x_15, if x_15 drinks water, then x_15 is taking a plane. Jennifer is a carpenter or Susan is not taking a plane.
If Susan takes a plane, then Jennifer is a carpenter can be inferred via the rewriting rule.
