Example Input: 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.

Example Input: Passage: The Bedrock Community Players is mounting A Christmas Carol, and all of the town's citizens are either planning to attend or be involved in the production: Barney Rubble is playing Bob Cragit, with Betty as Mrs. Cragit and his son Bamm-Bamm as Tiny Tim; Mr. Slate is Jacob Marbley; Wilma Flintstone is serving as the stage manager, while her daughter Pebbles plays Martha Cragit; even Dino has a role, playing the Cragit's family pet. It is Fred, though, who has landed the leading role of Ebonezer Scrooge. Unfortunately, he has let his role go to his head, thinking himself a star and spending all of his time rehearsing his lines rather than focusing on his job or family. On Christmas Eve, in his rush to get to work, Fred forgets that he must take Pebbles to "cave care", and later to pick her up from cave care. When Fred arrives at the theater, he discovers a furious Wilma, who breaks down in tears as she tells Fred about his mistake.

Example Input: Passage: At the same time, other explanations were proposed that did not concord with general relativity. Edward Milne proposed an explanation compatible with special relativity but not general relativity that there was a giant explosion that could explain redshifts (see Milne universe). Others proposed that systematic effects could explain the redshift-distance correlation. Along this line, Fritz Zwicky proposed a "tired light" mechanism in 1929. Zwicky suggested that photons might slowly lose energy as they travel vast distances through a static universe by interaction with matter or other photons, or by some novel physical mechanism. Since a decrease in energy corresponds to an increase in light's wavelength, this effect would produce a redshift in spectral lines that increase proportionally with the distance of the source. The term "tired light" was coined by Richard Tolman in the early 1930s as a way to refer to this idea.
