Final answer:
The Plains Indians were nomadic tribes known for their skilled horsemanship. They followed buffalo herds, lived in tipis, and did not have a maritime culture or permanent farming settlements.
Step-by-step explanation:
The Plains Indians were a diverse group of Native American tribes that inhabited the Great Plains of North America. Contrary to some of the presented options, they were largely nomadic and known for being expert horsemen. They relied on the buffalo for food, shelter, and other necessities and followed the herds' migration across the plains. This nomadic lifestyle was facilitated by the use of horses, which they became highly skilled at riding after the reintroduction of the horse to North America by the Europeans.
They lived in movable homes called tipis, which were easily put up and taken down as the tribes moved following the buffalo. The Plains Indians did not have a 'strong maritime culture,' as they were centered in land-locked areas, and they were not predominantly 'sedentary farmers' with 'permanent settlements' like some other indigenous cultures.
