Answer: d. All Native Groups lived with poor soil and limited agriculture
Explanation:
The regions that the Natives occupied did not have very fertile soil so the Natives were limited in the Agricultural ventures even though some groups like the Caddos and Jumanos did more farming than the rest.

b.theory of comparative advantage
Explanation:
Comparative advantage theory uses the concept of opportunity cost to measure the efficiency of each firm in producing a good or service. If Company A has a higher opportunity cost than Company B in producing a service, it is best to let Company B perform this service, while A must specialize in another activity. This may apply to companies that have the option of producing components of their final product or outsourcing these components. If the opportunity cost of a third party firm is lower, that firm will be more efficient in producing that component. Then the company can use its time and resources for other activities and purchase the outsourced firm's component. This way, the firm will be allowing another company to do part of the business because that other company is more productive in that particular service.
