The key answer of exercise 1

Chief Luther Standing Bear was a Native American leader, author, educator, and spokesperson for the Lakota Sioux tribe. He was born in 1868 near the Missouri River in present-day South Dakota, in the area that was once the Great Sioux Reservation. Standing Bear was a prominent figure in the late 19th and early 20th centuries, advocating for Native American rights, cultural preservation, and understanding between Indigenous and non-Indigenous peoples. He lived primarily in the Dakotas and Nebraska, where he was involved in tribal affairs and worked to preserve Lakota traditions and teachings. Standing Bear's writings, including his autobiography "My People, the Sioux," are significant contributions to Native American literature and provide valuable insights into Lakota culture and history.
