1. A)the East
2. In the east the highest factor of water use is steam/electric demonstrating the city life and mostly urban way of life in the east. In the west the highest use of water lies within irrigation and agriculture displaying the farming and rather rural way of life. The two lifestyle differences affect the water usage within different regions.
3. The arable land and nice weather in the west makes it perfect for farming and agriculture which is why the most common use of water is for that purpose. The harsh winters of the east and south make these regions less common for farming and therefore use less water for such means. The east south and midwest are definitely effected by the population's culture. Especially in the east where public transportation is so common, water is clearly the most useful in the steam and electric field.
