The best answer here would be pencil.
Artists use pencil to make sketches and create studies. They then use these sketches and studies to create their final larger piece. They use pencil because it's quick, can be corrected, lightweight and easy to use. Before pencils artists would make charcoal drawings but once we had pencils it made sense to use them as they aren't messy like charcoal.
1-3, 2-1, 3-2 that should be the correct order
60,000 - 70,000 that should be the answer
Most of the time, White's watercolor paintings definitely did not portray calmness because his paintings often portrayed Native Americans at war, hunting, or partaking in sacrifice. They definitely documented the lives of Woodland peoples...he acted as an artist mapmaker, documenting the Native American culture surrounding him. Though some of his pieces did portray European culture, they were vastly outnumbered by those portraying Native American culture.
The answer is, therefore, "They documented the lives of Woodland peoples"
