Background: The Mississippian culture was a mound-building Native American civilization archeologists date from approximately 800 CE to 1600 CE, varying regionally. It was composed of a series of urban settlements and satellite villages (suburbs) linked together by a loose trading network, the largest city being Cahokia, believed to be a major religious center. The civilization flourished from the southern shores of the Great Lakes at Western New York and Western Pennsylvania in what is now the Eastern Midwest, extending south-southwest into the lower Mississippi Valley and wrapping easterly around the southern foot of the Appalachians barrier range into what is now the Southeastern United States. The Mississippian way of life began to develop in the Mississippi River Valley (for which it is named).
Context: The Caddoan Mississippian area, a regional variant of the Mississippian culture, covered a large territory, including what is now eastern Oklahoma, western Arkansas, northeastern Texas, and northwestern Louisiana. Archaeological evidence has led to a scholarly consensus that the cultural continuity is unbroken from prehistory to the present, and that the Caddo and related Caddo language speakers in prehistoric times and at first European contact are the direct ancestors of the modern Caddo Nation of Oklahoma. The climate in this area was drier than areas in the eastern woodlands, hindering maize production, and the lower population on the plains to the west may have meant fewer neighboring competing chiefdoms to contend with. Major sites such as Spiro and the Battle Mound Site are in the Arkansas River and Red River Valleys, the largest and most fertile of the waterways in the Caddoan region, where maize agriculture would have been the most productive. The sites generally lacked wooden palisade fortifications often found in the major Middle Mississippian towns. Living on the western edge of the Mississippian world, the Caddoans may have faced fewer military threats from their neighbors. Their societies may also have had a somewhat lower level of social stratification. The Caddoan people were speakers of one of the many Caddoan languages. The Caddoan languages once had a broad geographic distribution, but many are now extinct. The modern languages in the Caddoan family include Caddo and Pawnee, now spoken mainly by elderly people. Hernando de Soto led an expedition into the area in the early 1540s, he encountered several native groups now thought to have been Caddoan. Composed of many tribes, the Caddo were organized into three confederacies, the Hasinai, Kadohadacho, and Natchitoches, which were all linked by their similar languages.

Answer: a regional variant of the Mississippian culture,

Background: Fred McFeely Rogers (March 20, 1928 - February 27, 2003) was an American television personality, musician, puppeteer, writer, producer, and Presbyterian minister. Rogers was famous for creating, hosting and composing the theme music for the educational preschool television series Mister Rogers' Neighborhood (1968-2001), which featured his kind-hearted grandfatherly personality, and direct connection to his audiences. Originally trained and ordained as a minister, Rogers was displeased with the way television addressed children at the time, and made an effort to change this when he began to write for and perform on local Pittsburgh-area shows dedicated to youth. Rogers developed his own show on WQED in 1968, and it was distributed nationwide by Eastern Educational Television Network.
Context: Rogers was born in Latrobe, Pennsylvania, 40 miles (65 km) southeast of Pittsburgh, to James and Nancy Rogers; he had one sister, Elaine. Early in life, he spent much of his free time with his maternal grandfather, Fred McFeely, who had an interest in music. He would often sing along as his mother would play the piano, and he himself began playing at five. He obtained a pilot's license while still in high school. Rogers graduated from Latrobe High School (1946). He studied at Dartmouth College (1946-48), then transferred to Rollins College in Winter Park, Florida, where he earned a B.A. in Music Composition in 1951. Rogers was also a trained general aviation pilot. At Rollins, he met Sara Joanne Byrd (born c. 1928), an Oakland, Florida, native; they married on June 9, 1952. They had two sons, James (b. 1959) and John (b. 1961). In 1963, Rogers graduated from Pittsburgh Theological Seminary and was ordained a minister in the United Presbyterian Church in the U.S.A. Rogers had an apartment in New York City and a summer home on Nantucket island in Massachusetts. Rogers was red-green color blind, swam every morning, and neither smoked nor drank. He was a vegetarian on ethical grounds, stating "I don't want to eat anything that has a mother." Despite recurring rumors, he never served in the military. His office at WQED Pittsburgh famously did not have a desk, only a sofa and armchairs, because Rogers thought a desk was "too much of a barrier".
Question: what did he study?
Answer: he earned a B.A. in Music Composition in 1951. Rogers was also a trained general aviation pilot.

He also wrote the Beatles' songs "Don't Pass Me By" and "Octopus's Garden", and is credited as a co-writer of others, including "What Goes On" and "Flying".

Skiff at the Anderson Mesa Station of the Lowell Observatory, was named in Starr's honour. Starr was nominated for a 1989 Daytime Emmy Award for Outstanding Performer in a Children's Series for his role as Mr. Conductor in the television series Shining Time Station. In 2015, twenty-three years after he was inducted into the Rock and Roll Hall of Fame as one of the Beatles, Starr became the last Beatle to be inducted for a solo career. During the 50th Grammy Awards, Starr, George Martin and his son Giles accepted the Best Compilation Soundtrack award for Love. On 9 November 2008, Starr accepted a Diamond Award on behalf of the Beatles during the 2008 World Music Awards ceremony in Monaco.
