Example Input: Question: How old was Adrian "King" Cole the year that headquarters RAAF Station Richmond was formed as a separate entity? Passage 1:The Indian Squads were announced on 13 February. Dhawal Kulkarni got his maiden call up to the national squad, having been selected for the test squad after a strong debut Ranji trophy season where he was the highest wicket taker. L Balaji made a return to the Test squad after a five-year hiatus having last played in a test in 2004. Balaji was dropped from the ODI squad after he played in a single match in the previous tour, he was replaced by the now fit Munaf Patel. In the test squad Balaji replaced Pragyan Ojha with the selectors opting for an extra seamer instead of an extra spinner for the tour. Ojha retained his place in the ODI and T20 squads. Subramaniam Badrinath was dropped from the test squad in favour of reserve Wicket-Keeper Dinesh Karthik after Karthik too had a strong Ranji trophy season. Karthik was selected for all three squads, replacing Jadeja in the ODI squad. Ravindra Jadeja's impressive ODI debut was rewarded with a call up to the Twenty20 squad but Jadeja will be replaced by Sachin Tendulkar for the subsequent ODI series. Munaf Patel made a return to all three squads after having to pull out midway through the previous tour of Sri Lanka due to injury. Harbhajan Singh also made a return to all three squads after having to pull out at the beginning of the previous tour to Sri Lanka due to injury.
Passage 2:A military flying school was set up at the site of the present-day RAAF base on 28August 1916, when the area was known as Ham Common. RAAF Station Richmond was established on 30June 1925 as the fledgling service's first air base outside Victoria. Its initial flying unit was No.3 (Army Cooperation) Squadron, operating Airco DH.9 light bombers and Royal Aircraft Factory S.E.5 fighters, and for the next decade the commanding officer of No.3 Squadron was also in charge of the base. Among these were Squadron Leaders Frank Lukis (192530), Harry Cobby (193031), and Bill Bostock (193133). Headquarters RAAF Station Richmond was formed as a separate entity on 20April 1936, under the command of Group Captain Adrian "King" Cole. Other units, including No.22 Squadron flying Hawker Demons, and No.2 Aircraft Depot, had been established in the preceding months. No.4 (General Reconnaissance) Squadron was formed in May 1937, followed by No.6 (General Reconnaissance) Squadron in March 1939. Two Fleet Cooperation units were also established, No.5 Squadron in April 1936 and No.9 Squadron in January 1939. No.23 (General Purpose) Squadron formed in February 1939. As well as an Air Force base, in its pre-war days Richmond was used as a supplementary airport for Sydney; various aviation pioneers employed it in the 1930s, including Charles Kingsford Smith and Jean Batten.
Passage 3:Campbell began her career as a dietitian at the Baptist College in Brandon, Manitoba. Immigrating to the United States in 1909, she took employment in South Bend, Indiana at the Epworth Hospital as a dietitian and instructor in domestic science and remained until 1911. She returned from Canada in 1914 and entered the Pasadena Hospital Training School for Nurses. In 1917, she graduated having earned her RN designation. The following year, she joined the Nurse Reserves of the United States Army Nurse Corps and began working as a staff nurse at the base hospital of Camp Fremont in Palo Alto, California. After serving at Letterman General Hospital, in San Francisco, she was sent to Fort Leavenworth, Kansas in 1920, to take up a post at the hospital for the United States Disciplinary Barracks. With this move, she became an American citizen and was transferred as a second lieutenant to the Regular Army of the Nurse Corps. Between 1921 and 1922, she was deployed to Coblenz, Germany, serving with the Allied Occupation Forces assisting with Russian famine refugees, influenza victims and war casualties. Returning to the United States, in 1924, she was promoted to first lieutenant after passing the Chief Nursing Examination.

Example Input: Question: How long after the Battle of Princeton did the war during which Fort Mercer was built end? Passage 1:The Calgary Flames selected him in the eighth round, 182nd overall at the 1981 NHL Entry Draft, and he began his professional career in 198384 with a 30-point season for the Colorado Flames of the Central Hockey League (CHL). He then spent the majority of three seasons in the American Hockey League (AHL) with the Moncton Golden Flames. He was named to the AHL second All-Star Team in 198485, and served as captain of the Golden Flames in 198586. DeGray appeared in one NHL game that season, making his NHL debut with Calgary on March 6, 1986, against the New York Rangers. He played a part-time role in Calgary in 198687; in 27 games with the Flames, DeGray scored six goals and seven assists.
Passage 2:Musicki was stationed in Slavonski Brod at the time of the Axis invasion of Yugoslavia in April 1941 and served as the Royal Yugoslav Army commander responsible for the railroad between Belgrade and Zagreb in the rank of colonel. He demonstrated his support for the Germans by helping their forces during the invasion. Yugoslavia was quickly conquered by the Axis powers and Musicki remained in Slavonski Brod for several months after the conquest. He attempted to join the Ustase Militia there, but was rejected. He went to Belgrade in mid-August, where he was received by Zbor leader Dimitrije Ljotic. On 6 October, Milan Nedic, the Prime Minister of the Axis-installed puppet Government of National Salvation, appointed Musicki to lead the Serbian Volunteer Command (, SDK). Musicki was involved in executing Serb civilians in the town of Cacak in December 1941. He and Milan Acimovic contacted Chetnik leader Draza Mihailovic on 5 December, possibly in an effort to warn him in advance of the assault the Germans had planned, codenamed Operation Mihailovic. This action prompted the Germans to question Musicki's loyalty. He was removed from command at the end of 1941 and imprisoned by the Germans, but was later freed at Nedic's intervention.
Passage 3:Fort Mercer was a fort on the Delaware River in New Jersey constructed by the Continental Army during the American Revolutionary War. Built by Polish engineer Thaddeus Kosciuszko under the command of George Washington, Fort Mercer was built in 1777 to block the approach to Philadelphia, Pennsylvania in concert with Fort Mifflin on the Pennsylvania side. Fort Mercer was located in an area called Red Bank, in what is now the borough of National Park, Gloucester County, New Jersey. The fort was named in honor of Brigadier General Hugh Mercer who had died earlier that year at the Battle of Princeton. The fort's site is now part of Red Bank Battlefield Historical Park, which includes a monument and museum. Several cannons attributed to British warships lost supporting the attack on the fort, and others found buried at the fort itself, are in the park.

Example Input: Question: How old was Rudi Gernreich when the monokini was introduced? Passage 1:By making an analogy with words like bilingual and bilateral containing the Latin prefix "bi-" (meaning "two" in Latin), the word bikini was first back-derived as consisting of two parts, [bi + kini] by Rudi Gernreich, who introduced the monokini in 1964. Later swimsuit designs like the tankini and trikini further cemented this derivation. Over time the "kini family" (as dubbed by author William Safire), including the "ini sisters" (as dubbed by designer Anne Cole), expanded into a variety of swimwear including the monokini (also known as a numokini or unikini), seekini, tankini, camikini, hikini (also hipkini), minikini, face-kini, burkini, and microkini. The Language Report, compiled by lexicographer Susie Dent and published by the Oxford University Press (OUP) in 2003, considers lexicographic inventions like bandeaukini and camkini, two variants of the tankini, important to observe. Although "bikini" was originally a registered trademark of Reard, it has since become genericized.
Passage 2:Joss Whedon and Brian K. Vaughan collaborated in breaking down the story, before Vaughan penned the four-part story individually. Vaughan had previously pitched the broad strokes of the story at a dinner with Whedon, Tim Minear and Drew Goddard as a direct-to-DVD Faith movie. There were some presumptions that Vaughan would have difficulty writing the characters' dialogue, given that he wasn't a member of the TV series' writing staff. Despite so, Vaughan proved otherwise. Whedon himself was compelled to tell Vaughan what great lines he had written to Faith specifically. His writing, like the series', featured numerous pop-culture references. The title itself refers to a verse from the song "God Save the Queen" by the Sex Pistols. Other rock song lyrics are mentioned by characters as well: Faith tells Giles she's "the go-to girl for dirty deeds done dirt cheap," whereas Roden paraphrases Pink Floyd's song "Another Brick in the Wall" with the phrase "as a wise man once said, you can't have any pudding if you don't eat your meat." Giles, sporting a jumper with a Yellow Submarine design, refers to "the great bearded wizard of Northampton": a nod to legendary comic book writer and magician Alan Moore. Buffy refers to Lady Genevieve and her accomplices as Faith's 'droogs', a term used in Anthony Burgess' A Clockwork Orange to define friend or associate. Finally, whilst training, Xander makes reference to Snake Plissken, the eye-patch wearing anti-hero of Escape from New York.
Passage 3:Graham Clarke was born in Holy Name Medical Center in Teaneck, New Jersey on July 11, 1970. Clarke's parents, Lorain Maria Clarke (nee Meola), a homemaker, and Thomas Michael "Moose" Clarke, a stockbroker were married in 1960 and had three children before Graham: Thomas in 1961, Dennis in 1962, and Martin in 1965. He spent the first seven years of his life in a split-level home in Dumont, New Jersey. He was frequently in the room when his older brother Tommy would have guitar lessons with musician Bob Berger. Bob noted one time when a screaming Graham had scarlet fever "That boy's screaming on key! That's a C note." Such exposure to music had an obvious influence on him and there is an oft-told family story that claims the first song Graham ever learned to sing was "Me and Julio Down by the Schoolyard," a popular song Tommy was learning on the guitar at the time. At the age of seven, his family moved one town over to Oradell, where he attended St. Joseph Grammar School, and later Bergen Catholic High School. Neither school had a music program so Graham taught himself how to play the guitar using his brother's old fake books.
