Input: Consider Input: Passage: Samuel James "Sam" Ervin Jr. (September 27, 1896April 23, 1985) was an American politician. A Democrat, he served as a U.S. Senator from North Carolina from 1954 to 1974. A native of Morganton, he liked to call himself a "country lawyer," and often told humorous stories in his Southern drawl. During his Senate career, Ervin was a legal defender of the Jim Crow laws and racial segregation, as the South's constitutional expert during the congressional debates on civil rights. Unexpectedly, he became a liberal hero for his support of civil liberties. He is remembered for his work in the investigation committees that brought down Senator Joseph McCarthy in 1954 and especially for his investigation of the Watergate scandal in 1972 that led to the resignation of Richard Nixon.

Input: Consider Input: Passage: John Silvester, the Recorder of London referenced the spectre of Napoleon Bonaparte and the burgeoning Napoleonic Wars in his announcement of Perring's appointment, stating that "At a time so awful as the present, when the country is threatened by an implacable and unprincipled enemy, it is of the last importance that the civic chair should be filled by a person in whom the greatest confidence can be placed". Silvester ominously warned Perring that "The keys of the Metropolis are placed in your hands, at the moment when the enemy are at the gates". The ball held later that day at Guildhall was opened with a minuet danced by Perring's eldest daughter and the Spanish Ambassador. The Napoleonic wars and the threat of a French invasion had led to coastal batteries being built as fortifications along the south coast of England in the summer of 1803. Perring was furious to find that a battery had been built on land that he owned at the mouth of the River Yealm in Devon, and wrote to the Secretary of War, Lord Hobart. Perring was eventually pacified by many letters from John Graves Simcoe, who was in charge of the construction of the defences. With the threat of invasion by the French still present, Perring presented the colours of the Corporation of London to the ten regiments of the London Loyal Infantry who assembled at Blackheath on 18 May 1804. Perring was accompanied on the grand procession to Blackheath by the Earl of Harrington, Earl Amherst and Prince Frederick, Duke of York.

Input: Consider Input: Passage: The son of Gordie Ion, Ion graduated from Burnaby North Secondary School. In 1981, the Portland Timbers selected him in the first round of the North American Soccer League draft. However, he lost the entire 1981 season with a knee injury. He came back in 1982 and played nine games, but the team folded at the end of the season. He then signed with the Montreal Manic, but that team collapsed at the end of the 1983 season. On November 10, 1983, the Fort Lauderdale Strikers purchased his contract from the Manic. The Strikers sent Ion to the Tulsa Roughnecks during the 1984 pre-season. When the NASL collapsed at the end of the season, Ion moved to the Los Angeles Lazers of the Major Indoor Soccer League. He remained with the Lazers until March 26, 1987 when the team traded him to the Minnesota Strikers in exchange for Thompson Usiyan. He finished the season with the Strikers. On October 2, 1987, the Strikers traded him to the San Diego Sockers in exchange for draft picks and cash. On November 6, 1987, the Sockers waived Ion during the pre-season as part of a salary reduction move. The Chicago Sting quickly signed him and he spent the 1987–1988 season in Chicago. The Sting, facing financial collapse, released Ion and ten other players on June 2, 1988. Ion then moved to the Kansas City Comets for two seasons. In 1990, he moved to the Tacoma Stars for two seasons.
