Explanation:

- Preindustrial: Economies characterized primarily by agriculture and subsistence living, with minimal industrial or technological development. Not reflective of modern economies like Canada and the USA.

- Postindustrial: Economies that have moved beyond heavy industry to service-based industries, advanced technology, and information services. This is indicative of the current state of Canada and the USA.

- Multi-industrial: Typically refers to economies with diverse industrial sectors. While aspects of these countries may be multi-industrial, the term doesn't fully capture their modern, service-oriented economies.

- Non-industrial: Economies with little to no industrial activity, often focused on simple, traditional practices. This does not describe Canada or the USA.
