Answer:
The correct answer is D. The Folsom culture was found in what today is the Great Plains area.
Explanation:
The Folsom culture is an early prehistoric culture of the Paleo-Indian period in North America. Their distribution ranged from what is now northern Mexico to the southwestern United States, the Great Plains, and east of the Mississippi River in what is now Missouri and Illinois to the Great Lakes. The Folsom culture is dated to 8800–8200 BC, and followed the previous Clovis culture.
The characteristic artefacts of the Folsom culture were the flat projectile tips made of flint and other hornstones, which have been made into blades on both sides and have both long and wide retouchings. In addition, people used tees as blades, various scrapers, needles and awls.
