In three to five sentences, explain the relationship between Native Americans and the Spanish.(4 points)
The relationship between Native Americans and the Spanish was complex. Initially, the Spanish came to the Southwest as explorers and traders, seeking riches and territory. At first, they established friendly relations with some of the Native American groups and even intermarried with them. However, conflicts soon developed over land, resources, and religious differences, leading to violence and oppression. The Spanish imposed their culture and religion on the Native Americans, causing significant harm to their way of life and traditions. Nevertheless, the Spanish influence can still be seen today in the Southwest's art, architecture, and cuisine.
In three to five sentences, describe what gray water is and how it is being used in the Southwest.(4 points)
Gray water is a term used to refer to wastewater that is generated from household and commercial activities, such as bathing, laundry, and dishwashing. Unlike sewage water, gray water is not contaminated with fecal matter and can be reused for certain purposes, such as landscaping and irrigation. In the Southwest, where water scarcity is a significant concern, gray water systems have become increasingly popular as a way to conserve water resources and reduce overall water usage. These systems capture, treat, and reuse gray water, thereby increasing the overall water-supply efficiency and lowering the amount of water that is needed for gardening and landscaping purposes.
