Question: Passage: Williamson's early film work included roles in M*A*S*H (1970) and Tell Me That You Love Me, Junie Moon (1970). He portrayed an escaped slave who flees westward in The Legend of Nigger Charley (1972). He played the role of an African-American gangster in the film Black Caesar (1973) and its subsequent sequel, Hell Up in Harlem (also 1973). Williamson also starred in the 1975 western film Boss Nigger, in which he played the title role. After this he appeared as an actor in several films, most of which are considered to be of the "blaxploitation" genre. Williamson starred alongside Peter Boyle and Eli Wallach in the movie Crazy Joe (1974). In 1974, Williamson was selected by the ABC television network as a commentator on Monday Night Football to replace Don Meredith, who had left to pursue an acting and broadcasting career at rival network NBC. Williamson was used on a few pre-season broadcasts, but was quickly declared unsuitable by ABC. He was relieved of his duties at the beginning of the regular season, becoming the first MNF personality not to endure for an entire season. He was replaced by the fellow former player (and fellow Gary, Indiana, native) Alex Karras.

Question: Passage: Benjamin Thompson was a Loyalist during the American Revolution, and fled the country in 1775 when the British evacuated Boston. He returned late in the Rev War commanding the King's American Dragoons, who saw action in the Southern states. He returned to England after the British surrender. He eventually settled for a time in the Holy Roman Empire, where he acquired the title of Count Rumford, and where he performed his groundbreaking research into the design of heating systems. This research resulted in a series of improvements to home heating systems, notably the Rumford stove, a shallow fireplace that more efficiently projected heat into a room than older and larger fireplaces. While in Munich, Thompson oversaw reforms of the indigent welfare system of Bavaria, and designed the city's famous English Garden. Thompson was also an inveterate and practical tinkerer, developing new versions of everyday utensils. He also proposed in 1799 the establishment in the United Kingdom of a research organization, which resulted in the founding of the Royal Institution. Although he never returned to the country of his birth, he did endow a professorial chair at Harvard College, and established the Rumford Prize, an annual award given by the American Academy of Arts and Sciences. He died in Paris in 1814.
