poizon [28]

Answer:

"rules of origin"

Explanation:

An rule of origin is a criterion chosen by countries or regional blocks to characterize the origin of goods. The Rules of Origin have as their object the determination of the origin of a product, thus considered the place of manufacture or where it has received a substantial transformation. In trade agreements the rules of origin define the conditions under which an importing country may consider a product originating in an exporting country that is a member of that agreement and consequently receive preferential treatment, ie if it benefits from a partial or full reduction in import tax.

An example of a rule of origin can be seen in the question above, where certain textiles are made in the United States, shipped to other countries, combined in making apparel with textiles made in those other countries - and then re-exported back to the United States.

Explanation:

The contrast between the cold winters and warm summers force the Native American to be smart when managing their hunting and agricultural activities.  They focused their hunting and farming during the warm summer as an  effort to accumulate enough food throughout the winters (since very few plants can grow and animal lives nearby when the weather is really cold).

The cold winters also forced them to find a reliable way to warm themselves to survive the temperature.

Both of these problems can be solved by using the animal remains. The meat provide them with nutrition for them to survive and the fur can be used to provide warmth and comfort.

This is why the concept of Spirit Animals are known among native American culture. They do it as a form of respect to them since the animals enable their tribe members to live.
