Problem: Background: Ross James Brawn OBE (born 23 November 1954) is the Formula One Managing Director of Motorsports and technical director. He is also a former motorsport engineer and Formula One team principal. He had worked for a number of Formula One teams, serving as the technical director of the championship-winning Benetton and Ferrari teams. He took a sabbatical from the sport in 2007 but returned to F1 for the 2008 season as Team Principal of Honda.
Context: His career in motorsport began in 1976 when he joined March Engineering in the town of Bicester as a milling machine operator. Soon afterwards he joined their Formula 3 racing team as a mechanic. Brawn was hired by Sir Frank Williams in 1978 as a machinist for the newly formed Williams team. He quickly moved up through the ranks, working in the R&D department with Frank Dernie and as an aerodynamicist in the team's wind tunnel.  Brawn joined the Haas Lola team in 1985 and was part of Neil Oatley's design team at FORCE that produced both the Lola THL1 and THL2 cars used by the team. However, with the 4 cylinder Hart engine in the THL1 and the new Ford V6 turbo powering the THL2, results were scarce against teams like McLaren and Williams with their TAG-Porsche and Honda turbo engines. This was despite the cars generally being regarded by most in the F1 paddock as being the best handling cars on the grid, as well as having 1980 World Champion Alan Jones and former factory Ferrari and Renault driver Patrick Tambay as the drivers. When the Haas team left F1 at the end of the 1986 season, Brawn moved to Arrows. There he designed the Megatron powered Arrows A10 and its update, the A10B for the 1987 and 1988 seasons respectively and the Ford V8 powered Arrows A11 used in 1989.  Later in 1989 Brawn moved to the Jaguar Sportscar racing division, and was lead designer on the Jaguar XJR-14 which won the 1991 World Sportscar Championship.
Question: How long did he work as a mechanic?
Answer: Brawn was hired by Sir Frank Williams in 1978 as a machinist for the newly formed Williams team.

Background: Native Americans, also known as American Indians, Indians, Indigenous Americans and other terms, are the indigenous peoples of the United States. There are over 500 federally recognized tribes within the U.S., about half of which are associated with Indian reservations. The term excludes Native Hawaiians and some Alaska Natives. The ancestors of modern Native Americans arrived in what is now the United States at least 15,000 years ago, possibly much earlier, from Asia via Beringia.
Context: Iroquois Culture: The Iroquois League of Nations or "People of the Long House", based in present-day upstate and western New York, had a confederacy model from the mid-15th century. It has been suggested that their culture contributed to political thinking during the development of the later United States government. Their system of affiliation was a kind of federation, different from the strong, centralized European monarchies.Leadership was restricted to a group of 50 sachem chiefs, each representing one clan within a tribe. The Oneida and Mohawk people had nine seats each; the Onondagas held fourteen; the Cayuga had ten seats; and the Seneca had eight. Representation was not based on population numbers, as the Seneca tribe greatly outnumbered the others. When a sachem chief died, his successor was chosen by the senior woman of his tribe in consultation with other female members of the clan; property and hereditary leadership were passed matrilineally. Decisions were not made through voting but through consensus decision making, with each sachem chief holding theoretical veto power. The Onondaga were the "firekeepers", responsible for raising topics to be discussed. They occupied one side of a three-sided fire (the Mohawk and Seneca sat on one side of the fire, the Oneida and Cayuga sat on the third side.)  Elizabeth Tooker, an anthropologist, has said that it was unlikely the US founding fathers were inspired by the confederacy, as it bears little resemblance to the system of governance adopted in the United States. For example, it is based on inherited rather than elected leadership, selected by female members of the tribes, consensus decision-making regardless of population size of the tribes, and a single group capable of bringing matters before the legislative body.  Long-distance trading did not prevent warfare and displacement among the indigenous peoples, and their oral histories tell of numerous migrations to the historic territories where Europeans encountered them. The Iroquois invaded and attacked tribes in the Ohio River area of present-day Kentucky and claimed the hunting grounds. Historians have placed these events as occurring as early as the 13th century, or in the 17th century Beaver Wars.  Through warfare, the Iroquois drove several tribes to migrate west to what became known as their historically traditional lands west of the Mississippi River. Tribes originating in the Ohio Valley who moved west included the Osage, Kaw, Ponca and Omaha people. By the mid-17th century, they had resettled in their historical lands in present-day Kansas, Nebraska, Arkansas and Oklahoma. The Osage warred with Caddo-speaking Native Americans, displacing them in turn by the mid-18th century and dominating their new historical territories.
