Which term refers to nomadic Plains tribes that depended on buffalo and horse and used sign language to communicate with other tribes?

• A. Pueblo
• B. Plain Indians
• C. Circumpolar
• D. Astrolabe

Answer: (B)

The main idea here is naming the group of nomadic Plains tribes who followed buffalo, adopted horses, and used cross-tribal signaling. The best term is Plain Indians (commonly written Plains Indians). These groups lived on the Great Plains and moved with buffalo herds, later integrating horses into their way of life. To communicate with other tribes across different languages, they used Plains Sign Language, a flexible system that facilitated hunting coordination, trade, and diplomacy across vast distances. Pueblo, by contrast, are peoples of the Southwest who built settled communities; Circumpolar refers to Arctic/Subarctic peoples; and an astrolabe is a navigational instrument, not a people.
