Which artifact is most likely to have been made by American Indians of the Plains? A. gift basket B. flowerpot C. patchwork skirt D. leather bag

The artifact most likely to have been made by American Indians of the Plains is D. leather bag. Here's why:

1. The Plains Indians were known for their skill in working with animal hides. They used every part of the animals they hunted, including the hides, which they turned into clothing, tepees, and bags.

2. A gift basket (A) could be made by many different cultures, so it's not specific to the Plains Indians.

3. A flowerpot (B) is not typically associated with the nomadic lifestyle of the Plains Indians. They were more likely to use portable, durable items.

4. A patchwork skirt (C) is more associated with tribes in the Southeastern United States, like the Seminole, not the Plains.

So, based on these considerations, a leather bag (D) is the most likely artifact to have been made by American Indians of the Plains.
