Before the arrival of Europeans, the two most powerful and most populous empires in the Americas were those commonly referred to as the Incas (based in the Andes Mountains) and the Aztecs (based in central Mexico).

Explanation:

The Inca empire was one of the largest that encompassed part of Ecuador, Peru, Bolivia, Chile and Argentina (the vast majority of these countries have the Andes mountain range, which is why the Inca settlement was on that mountain range), on the other hand the Aztecs or Mexicas were settling in the central and southern of Mexico, precisely a curious fact of this pre-Hispanic town is that Mexico City is the place of one of its most significant legends of how they decided the place to reside.

if interdependence implies a two-way dependence, and if each partner is equally dependent on the other for success, then there is an equal commitment to the making the partnership successful. the advantage is sustainability of the relationship, the disadvantage is that decisions are "democratic" and therefore may take longer to reach and more likely to be a compromise (which is not always the best solution). as the interdependence moves away from equality, the decisions become more influenced by the more independent partner. in the extreme the relationship becomes more dictatorial and more like "master-slave". generally the relationship has less commitment in both directions and is more likely to be temporary.

if one generalizes (and one shouldn't), equity partnerships, which is probably what is implied by interdependence, can be slow to progress or change but durable. the extreme alternative, independent-dependent partnerships tend to be efficient but more fragile.

hope this but you will have to site your own evidence. : )

i’m   sure probably just geuss and see which one you can get right, i’m pretty sure it is the combination of goods and services
