Final answer:
Historically, societies in the Great Basin region responded to aridity by living in frequently barren areas, moving frequently, and building easily made and destroyed housing. The introduction of horses provided temporary increased mobility, but eventually, the discovery of gold and silver forced societies onto reservations.
Step-by-step explanation:
In response to the aridity of the Great Basin region historically, societies like the Shoshone, Paiute, and Ute lived in frequently barren areas and moved from place to place to forage. They built small settlements and easily made and destroyed housing from trees and brush to allow for mobility. The introduction of horses by Europeans provided temporary increased mobility, but the discovery of gold and silver eventually forced these societies onto reservations.
