Problem: Background: Osceola was named Billy Powell at birth in 1804 in the Creek village of Talisi. now known as Tallassee, Alabama, in current Elmore County. "The people in the town of Tallassee...were mixed-blood Native American/English/Irish/Scottish, and some were black. Billy was all of these."
Context: Through the 1820s and the turn of the decade, American settlers kept up pressure on the US government to remove the Seminole from Florida to make way for their desired agricultural development. In 1832, a few Seminole chiefs signed the Treaty of Payne's Landing, by which they agreed to give up their Florida lands in exchange for lands west of the Mississippi River in Indian Territory. According to legend, Osceola stabbed the treaty with his knife, although there are no contemporary reports of this. Five of the most important Seminole chiefs, including Micanopy of the Alachua Seminole, did not agree to removal. In retaliation, the US Indian agent, Wiley Thompson, declared that those chiefs were deposed from their positions. As US relations with the Seminole deteriorated, Thompson forbade the sale of guns and ammunition to them. Osceola, a young warrior rising to prominence, resented this ban. He felt it equated the Seminole with slaves, who were forbidden to carry arms. Thompson considered Osceola to be a friend and gave him a rifle. Osceola had a habit of barging into Thompson's office and shouting complaints at him. On one occasion Osceola quarreled with Thompson who had the warrior locked up at Fort King for a two nights until he agreed to be more respectful. In order to secure his release, Osceola agreed to sign the Treaty of Payne's Landing and to bring his followers into the fort. After his humiliating imprisonment, Osceola secretly prepared vengeance against Thompson. On December 28, 1835, Osceola, with the same rifle Thompson gave him, killed Wiley Thompson. Osceola and his followers shot six others outside Fort King, while another group of Seminole ambushed and killed a column of US Army, over 100 troops, marching from Fort Brooke to Fort King, in what Americans called the Dade Massacre. These nearly simultaneous attacks began the Second Seminole War.

Problem: Background: Edward Sapir (; January 26, 1884 - February 4, 1939) was an American anthropologist-linguist, who is widely considered to be one of the most important figures in the early development of the discipline of linguistics. Sapir was born in German Pomerania; his parents emigrated to United States of America when he was a child. He studied Germanic linguistics at Columbia, where he came under the influence of Franz Boas who inspired him to work on Native American languages.
Context: Sapir's special focus among American languages was in the Athabaskan languages, a family which especially fascinated him. In a private letter, he wrote: "Dene is probably the son-of-a-bitchiest language in America to actually know...most fascinating of all languages ever invented." Sapir also studied the languages and cultures of Wishram Chinook, Navajo, Nootka, Colorado River Numic, Takelma, and Yana. His research on Southern Paiute, in collaboration with consultant Tony Tillohash, led to a 1933 article which would become influential in the characterization of the phoneme. Although noted for his work on American linguistics, Sapir wrote prolifically in linguistics in general. His book Language provides everything from a grammar-typological classification of languages (with examples ranging from Chinese to Nootka) to speculation on the phenomenon of language drift, and the arbitrariness of associations between language, race, and culture. Sapir was also a pioneer in Yiddish studies (his first language) in the United States (cf. Notes on Judeo-German phonology, 1915). Sapir was active in the international auxiliary language movement. In his paper "The Function of an International Auxiliary Language", he argued for the benefits of a regular grammar and advocated a critical focus on the fundamentals of language, unbiased by the idiosyncrasies of national languages, in the choice of an international auxiliary language. He was the first Research Director of the International Auxiliary Language Association (IALA), which presented the Interlingua conference in 1951. He directed the Association from 1930 to 1931, and was a member of its Consultative Counsel for Linguistic Research from 1927 to 1938. Sapir consulted with Alice Vanderbilt Morris to develop the research program of IALA.
Question: what languages did he study?
Answer: Sapir's special focus among American languages was in the Athabaskan languages,
