Example Input: Question: Who designed Hans Klemm's first light aircraft? Passage 1:The head of the femur, which articulates with the acetabulum of the pelvic bone, comprises two-thirds of a sphere. It has a small groove, or fovea, connected through the round ligament to the sides of the acetabular notch. The head of the femur is connected to the shaft through the neck or collum. The neck is 45cm. long and the diameter is smallest front to back and compressed at its middle. The collum forms an angle with the shaft in about 130 degrees. This angle is highly variant. In the infant it is about 150 degrees and in old age reduced to 120 degrees on average. An abnormal increase in the angle is known as coxa valga and an abnormal reduction is called coxa vara. Both the head and neck of the femur is vastly embedded in the hip musculature and can not be directly palpated. In skinny people with the thigh laterally rotated, the head of the femur can be felt deep as a resistance profound (deep) for the femoral artery.
Passage 2:Born in Tel Aviv, Israel, on November 26, 1971, Huberman is the son of Holocaust survivors. He and his family moved to Oak Ridge, Tenn., when his father, a cancer researcher, began working at the Oak Ridge National Laboratory. Huberman attended the University of WisconsinMadison, graduating with a Bachelor's Degree in psychology and English in 1994. After graduation, he joined the Chicago Police Department where he initially served as a beat officer. While working full-time as a Chicago police officer, Huberman attended night classes at the University of Chicago and earned two advanced degrees in 2000, a Master of Social Work from the School of Social Service Administration and a Master of Business Administration from the university's Graduate School of Business (now the Booth School of Business). Huberman was a recipient of The Paul & Daisy Soros Fellowships for New Americans and an Albert Schweitzer Fellow while attending the University of Chicago.
Passage 3:Hans Klemm's first light aircraft was the Daimler L15 and the L20 had much in common with it. Both were cantilever monoplanes with twin open, tandem cockpits and engines of very low power. The L20's low wing distinguished it from its predecessor and had the advantage of providing a low centre of gravity and better view during the landing approach as well as better protection for occupants in case of crash landings. The low-set wing also allowed a shorter undercarriage on the L20, which was otherwise like that of the L15 with the wheels independently mounted on pairs of centrally hinged V-struts and with vertical shock absorbing legs to the wing underside. Wheels were sometimes replaced by floats. Intended from the start for serial production, the L20's structure was simplified, with a pentagonal cross-section fuselage lacking the L15's rounded upper and lower surfaces. The fuselage was wooden framed with canvas covering. The overall strength of the structure, which had a safety factor of 12, was emphasised.

Example Input: Question: Which power-switching election in the 1970s had more total votes? Passage 1:Secretary of State for Employment and Productivity Barbara Castle introduced an Employed Persons (Health and Safety) Bill in 1970 but the debate around the Bill soon generated a belief that it did not address fundamental issues of workplace safety. In the same year, the Occupational Safety and Health Act was passed into United States federal law. As a result, a committee of inquiry chaired by Lord Robens was established towards the end of Harold Wilson's first government. When the Conservative Party came to power following the 1970 United Kingdom general election, they gave Castle's Bill no parliamentary time, preferring to wait for the Robens Report which was published in 1972. Conservative Secretary of State for Employment William Whitelaw introduced a new Bill on 28 January 1974 but Labour were returned to power in the February 1974 United Kingdom general election and the Bill again lost. The new Labour administration finally secured the passage of a Bill that year.
Passage 2:June started with striker Mark Stewart having the second year of his contract cancelled. Following this Turnberry Homes signed a new two-year deal to continue as the club's shirt sponsors. Bobby Barr became the club's second signing of the summer, joining on a year long deal from Raith Rovers. Ross Forbes was announced as the club's third summer signing on 11 June - signing a season long deal nine years after a loan spell with the club. A day later the club's top scorer from the 201718 season, Calum Gallagher, signed a new one-year deal. The week ended with Grant Adam becoming the club's fourth signing of the summer, joining on a one year deal from Forfar Athletic. His arrival was followed by that of striker Rory Loy, who joined after leaving Falkirk, however Danny Handling turned down a new deal with the club to join Scottish League Two side Edinburgh City. Stuart Carswell was the next player to commit himself for another season, signing a new one-year deal after 54 appearances and two goals in his 18 months at the club. The following week defenders Ross Perry and Cammy Ballantyne signed for the club on year-long deals, and they were joined by Ryan Thomson who joined after leaving Stranraer. A day after signing Thomson marked his debut with a goal, which was added to by strikes from Calum Gallagher and Iain Russell (playing as a trialist) as Dumbarton overcame Lowland League side East Kilbride in their first friendly of the season.

Example Input: Question: What is the volume of the lake that the Yellowstone River feed and drain? Passage 1:Donawa came through the youth setup at Somerset Trojans, playing in the Player Development League and the U-14 KO Cup. He made his senior debut for Somerset on 2 January 2014, appearing off the bench in the Friendship Trophy final as the Trojans claimed a 32 victory against Hamilton Parish. He continued to appear for Somerset for four more seasons, albeit infrequently as he could only play for the club while on breaks from school. Donawa returned to Somerset during the 201415 season, playing against Robin Hood in the Friendship Trophy and helping the club to claim their first Bermudian Premier Division title in 22 years. He was unable to appear in the title-deciding victory over Southampton Rangers, however, after suffering a sprained ankle while on international duty. Donawa helped the club to another championship in 201516, appearing in the Friendship Trophy while on holiday from school. He scored the final goal of a 30 victory against Hamilton Parish in the semifinals, giving Somerset the chance to win their eleventh Friendship Trophy after the new year. Against PHC Zebras in the final, Donawa scored the winning goal just before halftime as the Trojans claimed a 21 victory. On 12 December 2016, Donawa scored his first career Bermudian Premier League goal. His eighth-minute strike, off an assist from Hubert Buttersfield, helped Somerset claim a 22 draw against Devonshire Cougars. His second league goal had to wait until the 201718 season, coming in a 31 victory over X-Roads Warriors on 11 December 2017. He also added a goal in the semi-finals of the Expansion League Festive Tournament later that month and played the full 90 minutes in a 33 draw with North Village Rams on 17 March that clinched Premier Division safety for Somerset. The match against North Village would mark Donawa's final game with the club, as he was unable to participate during the 201819 season due to injury and a lack of international clearance.
Passage 2:The river rises in northwestern Wyoming in the Absaroka Range, on the Continental Divide in southwestern Park County. The river starts where the North Fork and the South Fork of the Yellowstone River converge. The North Fork, the larger of the two forks, flows from Younts Peak. The South Fork flows from the southern slopes of Thorofare Mountain. The Yellowstone River flows northward through Yellowstone National Park, feeding and draining Yellowstone Lake, then dropping over the Upper and Lower Yellowstone Falls at the head of the Grand Canyon of the Yellowstone within the confines of the park. After passing through the Black Canyon of the Yellowstone downstream of the Grand Canyon, the river flows northward into Montana between the northern Absaroka Range and the Gallatin Range in Paradise Valley. The river emerges from the mountains near the town of Livingston, where it turns eastward and northeastward, flowing across the northern Great Plains past the city of Billings.
Passage 3:A halfback, Marhefka spent four seasons, 1920 through 1924, on Lafayette's football team under coach Jock Sutherland. In 1921 the squad went undefeated, but the college's president refused to allow them to compete in the Rose Bowl. After graduation, he was picked up by the Pottsville Maroons and played with them during their sole season in the Anthracite League, in which they were the champions. He remained with the team when they joined the National Football League the following year and was with them when, despite having the best record in the league, they were denied the 1925 NFL championship after being controversially suspended. He had a final season in professional football with the 1926 Philadelphia Quakers of the first American Football League, in which they were the champions. Marhekfa appeared in two games for the team during the season.
