Which of the following is not true of the North American Southwest?

a.

It was mainly made up of farming cultures, which were slower to arise in the American Southwest.

b.

The North American Southwest included the areas of present-day New Mexico, Colorado, Arizona, and Utah.

c.

They built large-scale irrigation systems and elaborate, multi-storied structures.

d.

The Natives of the North American Southwest produced an abundance of basalt sculpture.

The correct answer is d. The Natives of the North American Southwest produced an abundance of basalt sculpture. Basalt sculpture was actually more prominent among Native American groups who resided in Central America before the arrival of Europeans. Option a is true because before this contact, these Native American groups were initially nomadic hunters and gatherers, who eventually became dependent on maize and transformed into farming cultures, although it took quite a while for them to do so. Option b is true because, if you look at a map, North America comprises Canada and the US, and the southwestern region would be down and to the left, where New Mexico, Colorado, Arizona, and Utah are. Option c is true because the climate is hot and dry, so without irrigation systems, these groups of people would not have been able to live there.
