Example Input: Question: Who piloted the airplane that killed Mulgrew Nunatak in 1979? Passage 1:Carter started his career as an apprentice at Brighton & Hove Albion but failed to make the grade for the first team. He made his first team debut in April 1987 in a 1–1 draw with Blackburn Rovers, coming on as a substitute and almost scoring with his first touch. He subsequently dropped down to the Isthmian League where he spent a season with Billericay Town. He was signed by Fourth Division side Leyton Orient in July 1988 and remained a first team regular in his seven-year spell at the club, which included promotion to the Third Division in his first season with via the play-offs. In June 1995, he joined newly relegated Second Division side Peterborough United for a fee of £25,000. He was a first team regular in his first season with the club but dropped out of the side in his second season as the club narrowly avoided relegation twice. Following his release he spent time on trial at Cambridge United and Wycombe Wanderers, however, both were unsuccessful in earning a full-time contract. He subsequently signed for Welsh Premier League side Barry Town, where he spent two seasons and made a total of sixty league appearances, scoring ten goals. He later joined Southern League Premier side Merthyr Tydfil in 1999 and spent six seasons with the club making over 200 appearances. He was also the club captain. In the summer of 2005 he signed for newly promoted Welsh Premier League side Cardiff Grange Harlequins but only made eight league appearances and the side couldn't avoid relegation at the first attempt.
 Passage 2:Mulgrew Nunatak () is a prominent nunatak, 1,600 m, standing four nautical miles (7 km) east of Tentacle Ridge in the Cook Mountains. Its summit, standing at , is named Peter Crest. The nunatak was first mapped by the Darwin Glacier Party of the Commonwealth Trans-Antarctic Expedition (1956–58). Both it and its peak were named for Peter D. Mulgrew, a New Zealand adventurer who accompanied Sir Edmund Hillary to the South Pole and served as the chief radio operator at Scott Base. He perished in the Air New Zealand DC10 scenic flight to Ross Island, 28 November 1979, when the airplane crashed near Te Puna Roimata Peak ("spring of tears" peak) on the northeast slope of Mount Erebus, killing all 257 persons aboard.
 Passage 3:The northern segment of the fault runs from Hollister, through the Santa Cruz Mountains, epicenter of the 1989 Loma Prieta earthquake, then up the San Francisco Peninsula, where it was first identified by Professor Lawson in 1895, then offshore at Daly City near Mussel Rock. This is the approximate location of the epicenter of the 1906 San Francisco earthquake. The fault returns onshore at Bolinas Lagoon just north of Stinson Beach in Marin County. It returns underwater through the linear trough of Tomales Bay which separates the Point Reyes Peninsula from the mainland, runs just east of Bodega Head through Bodega Bay and back underwater, returning onshore at Fort Ross. (In this region around the San Francisco Bay Area several significant "sister faults" run more-or-less parallel, and each of these can create significantly destructive earthquakes.) From Fort Ross, the northern segment continues overland, forming in part a linear valley through which the Gualala River flows. It goes back offshore at Point Arena. After that, it runs underwater along the coast until it nears Cape Mendocino, where it begins to bend to the west, terminating at the Mendocino Triple Junction.

Example Input: Question: How old was Luke Taft when Daniel Day started the first woolen mill in Uxbridge? Passage 1:The American Taft family first settled in what later became Uxbridge in the 17th Century. A descendant, Luke Taft became one of the earliest industrial pioneers here.) Luke Taft was the son in law of Daniel Day, and married his daughter Nancy. In 1809, Daniel Day had started the first woolen mill in Uxbridge and the Blackstone River Valley, one of the first woolen mills in the US (third), a little bit downstream. The Wheelocks, (descended from the Rev. Ralph Wheelock, the pioneer of American public education), also settled in Uxbridge, in the 18th Century. Lt. Simeon Wheelock, a Revolutionary War soldier, fought and died in Shays' Rebellion. His son Jerry, became one of the earliest textile pioneers in Uxbridge, and worked with Luke Taft. Luke and Nancy (Day) Taft had a son, Moses, who born in January 1812. Jerry Wheelock's daughter, Sylvia A Wheelock, then married Moses Taft in 1834. Luke Taft established a mill at the site in 1833, and Moses Taft, (Luke's son and Daniel Day's grandson) established what later became the larger Stanley Mill in 1852. Uxbridge was an early industrial center that played key roles in the early textile industry in America, pioneering satinets, cashmeres, blended fabrics, and power looms for woolens. Stanley Woolen Mill later would become a legacy of both the Taft and Wheelock families, continuing woolen and textile innovations of Uxbridge, begun by Jerry, Luke and their contemporaries. Stanley Woolen Mill became the first mill to offer complete vertical integration from raw materials to clothing. Stanley Woolen Mill, was a continuously operating family business, from 1833 at the present site, and from 1809, with its connections to Daniel Day.

Example Input: Question: Who was the leader of Somalia's National Security Agency? Passage 1:Barton Stone Alexander (September 4, 1819 – December 15, 1878) was a Union Army lieutenant colonel, engineer regiment commander and chief engineer for the defenses of Washington during the American Civil War. In recognition of his service, in 1866, he was appointed to the brevet rank of brigadier general in the regular army, to rank from March 13, 1865. He was a graduate of the U.S. Military Academy at West Point and served in the United States Army's Corps of Topographical Engineers, which at times was both a part of and separate from the United States Army Corps of Engineers. After graduating from West Point as a second lieutenant in the Class of 1842, he served in the Mexican–American War, building fortifications to protect American supply lines in the advance on Mexico City. After the end of the war, he was stationed in Washington, D.C., where he served as architect for the Scott Building and Quarters Buildings at the U.S. Soldiers' Home and took over the completion of the Smithsonian Institution Building after dissatisfaction with the pace of the first architect caused him to be dismissed.
 Passage 2:Mohammed and a Kenyan extremist, thought to be Musa Hussein (a.k.a. Musa Sambayo), were driving in a car carrying $40,000 in United States dollars, as well as medicine, telephones, laptops and a South African passport in the Afgooye corridor, northwest of Mogadishu on 7 June 2011. Musa Hussein was known to Mohammed as Abdullahi Dere and is believed to have been involved in funding operations for al-Shabaab. At around 11:15 p.m., the car was stopped at a security checkpoint managed by the Somalian military (SNA) in the Sarkuusta area, in southwest Mogadishu. Captain Hassan Mohamed Abukar ordered the driver to switch on the light inside the car. The driver followed the order but switched the light on and off too quickly for the soldiers to identify the people in the car, then one of the occupants opened fire. An order was given to open fire on the car. Two occupants in the car were killed and buried in Mogadishu within 24 hours. A third occupant escaped. Somalia’s National Security Agency suspected one of the dead to be Fazul after examination of the belongings; DNA tests subsequently confirmed his identity. Documents found on his body indicated he was planning a number of attacks in Britain, one of which targeted the notable Eton College.
 Passage 3:G.W. Scott and Sons opened their first store in London, England, in 1661. Due to fire damage sustained during the Great Fire of London, they were forced to relocated their company to first Old Compton Street and then Charing Cross Road, in the central part of the city. The company is likely most well known as having developed the modern form of the picnic basket, which was unveiled in 1851 during the "Great Exhibition of the Works of Industry of All Nations" held in Crystal Palace of Hyde Park, London, the first of many world fair exhibitions during the Victorian Era. They also achieved a measure of international fame when G.W. Scott and Sons created 30 foot tall sculptures decorating the mall parade route for the coronation of Queen Elizabeth II, in addition to making the cradles used by the monarchy. Besides making specialty items for the British Royal Family and their residences (including silver baskets for Buckingham Palace), the company was also contracted by the government during the Second World War to make campaign trunks and furniture for the Army, and double hampers for parachute drops by the Airborne Division of the Royal Air Force.
