Example Input: Passage: Nelson was originally called Ffos-y-Gerddinen ("ditch of the rowan"), a relatively flat piece of land at the southern extremity of the Taff Bargoed Valley to the south of the hamlet of Llancaiach. It existed on a drovers trail from the South Wales coast towards Merthyr Tydfil and onwards to Brecon and Mid Wales, where an enterprising man built a coaching inn that he called Nelson, possibly after Admiral Lord Nelson and his victory at the Battle of Trafalgar. Had it not been for the development of the South Wales coalfield, Nelson would have remained just a coaching inn surrounded by fields. When the Llancaiach Colliery was developed from 1811, it created a need for new housing for the workers and heavy transport for the coal, which spilled onto the flat lands below the colliery.
 Link Information: The Battle of Trafalgar (21 October 1805) Answer: 21 October 1805

Example Input: Passage: In a highly unusual situation, two LP albums of the score were released. The recording rights had been granted to RCA Victor, which had invested in the show, but Merman was under contract to Decca Records, which refused to allow her to record the original cast album. Decca issued a 10-inch LP featuring Merman singing some of her songs, accompanied by arranger-conductor Gordon Jenkins and His Orchestra and Chorus, with vocalizing by Dick Haymes (who joined Merman in the show's biggest hit, "You're Just in Love", their single reaching Billboard magazine's number 30 for a week) and Eileen Wilson (who sang "It's a Lovely Day Today" with Haymes). RCA Victor went ahead with the original cast album replacing Merman with Dinah Shore. Merman was called back into the Decca studios to record additional songs from the show, and the label quickly re-released the album as a 12-inch LP under the title Ethel Merman: 12 Songs from Call Me Madam. The Victor album sold reasonably well, attaining the sixth spot on the Billboard popular album charts, but the LP was out of print from 1956 until RCA Red Seal reissued it briefly in 1977. Peaking at number two on Billboards popular album charts, Merman's Decca recording, which would appear on MCA Records beginning in 1973, stayed steadily in print until the end of the LP era. Merman's Madam album currently is available on a Decca Broadway CD, which also features Merman singing four Cole Porter tunes from the stage score of Panama Hattie (1940).

Example Input: Passage: In 1970, 22-year-old Crespo had dropped out of IST and was eventually drafted into military service in the Portuguese Colonial War. He transferred to Mozambique where his military occupation was to check the cement cargoes from Beira to the Cahora Bassa Dam construction site, near Tete. Some time later, due to his good fluency in English, he was placed in the press office of Kaúlza de Arriaga, the commander in chief of the Portuguese Armed Forces in Mozambique, who had coordinated a massive anti-guerrilla operation against FRELIMO separatists in 1970 - the Gordian Knot Operation. While serving in the army, Crespo also entered the newly created School of Medicine of the University of Lourenço Marques where he would complete a number of academic disciplines but did not graduate. He also married Helen de Souza from Johannesburg, a South African woman with Portuguese ancestry who worked in genetics. After the Carnation Revolution left-leaning military coup at Lisbon in April 1974, fresh out of the troop, Crespo fled Mozambique for South Africa.
