Example Input: Question: What is the population of the town where Gawler established his own firm? Passage 1:Maryanoff has been active in the fields of medicinal chemistry and organic chemistry. He is an inventor of topiramate, a unique sugar sulfamate drug, which has been marketed worldwide for the treatment of epilepsy and migraine, attaining annual sales of more than $2 billion. Topiramate is also a principal component of the antiobesity drug Qsymia. Maryanoff is an internationally renowned expert in drug design and drug discovery, especially in the application of protein structure-based drug design. He made seminal contributions to understanding the stereochemistry and mechanism of the Wittig reaction; adapted the cobalt-catalyzed alkyne trimerization to the synthesis of macrocycles; and devised novel peptides that undergo self-assembly to mimic native collagen structurally and functionally. Maryanoff is an author on 280 scientific publications, including several books (editor), book chapters, and review articles. He is an inventor on 100 issued U.S. patents, has presented over 185 invited lectures worldwide, and mentored 11 postdoctoral associates. Maryanoff organized and edited a special memorial issue of the Journal of Medicinal Chemistry to honor the memory of Dr. Paul Janssen (2005) and has served on numerous editorial advisory boards for scientific journals and research grant review committees.
 Passage 2:Gawler was born in Adelaide, South Australia, to Caroline (née Philpot) and Henry Gawler. His grandfather, George Gawler, was the second Governor of South Australia. Gawler attended St Peter's College, Adelaide, and then studied law at the University of Adelaide. Gawler was called to the bar in South Australia in 1886, and left for Western Australia later that year, establishing his own firm in Perth. At one time, he was in partnership with Robert Bruce Burnside, a future Supreme Court justice. Having previously served on the Peppermint Grove Road Board for a period, Gawler was elected to parliament at a 1910 Legislative Council by-election, which had been caused by the resignation of Walter Kingsmill. He died in office in May 1915 (aged 54), of typhoid fever. He had married Eva Mary Waldeck in 1893, with whom he had four children.
 Passage 3:Benfica's first competitive game was an away Primeira Liga opener against Rio Ave. Sánchez Flores did not have Reyes, and Jonathan Urretaviscaya started instead. At the Estádio dos Arcos, the home team scored first with a 55th-minute goal from José Semedo. A minute later Benfica evened the score, with Urreta assisting Nuno Gomes for the 1–1 final result. It was the fourth consecutive time that Benfica failed to win their league start. Sánchez Flores said that Rio Ave created unexpected problems: "It was not a easy game. We had a quality opponent, who left us trailing when we were not expecting it." During the last week of August Benfica brought in Honduran striker David Suazo on loan, sold right-back Nélson Marcos to Betis and was paired with Italian side Napoli in the UEFA Cup first-round draw on 29 August. A day later, Benfica hosted Porto for the first Clássico of the season. The visitors started better, converting a 10th-minute penalty kick for a Kostas Katsouranis foul against Lucho González. In the 56th minute, Cardozo exploited a mistake by Helton to head in the equaliser. Three minutes later Katsouranis was sent off, but Benfica held the tie until the final whistle. Quique Flores said, "It was a good game. In normal conditions we would have done better, but circumstances made it a little harder."

Example Input: Question: Which college where Harben was educated has the highest enrollment? Passage 1:The towers were designed as framed tube structures, giving tenants open floor plans, unobstructed by columns or walls. The framed tube design was introduced by Bangladeshi-American structural engineer Fazlur Rahman Khan in the 1960s. The design was accomplished by using many closely spaced perimeter columns, providing much of the structure's strength, with the gravity load shared with the core columns. The elevator system, which made use of sky lobbies and a system of express and local elevators, allowed substantial floor space to be used for office purposes by making the structural core smaller. The design and construction of the towers involved many other innovative techniques, such as wind tunnel experiments and the slurry wall for digging the foundation. Yamasaki also incorporated elements of Islamic architecture in the building's design, having previously designed Saudi Arabia's Dhahran International Airport with the Saudi Binladin Group.
 Passage 2:Beagle is a crater lying within the Margaritifer Sinus quadrangle (MC-19) portion of the planet Mars, the crater is one of multiple topographical depressions within the Meridiani Planum extraterrestrial plain, which was explored by the Opportunity rover. It was located by the rover in images taken on sol 855 (June 20, 2006), 310 metres (1,107 ft) away. It is on the edge of the much larger ejecta blanket surrounding the crater Victoria, named the Victoria Annulus. This impact crater was named in honor of HMS Beagle of the Royal Navy, ordered in February 1817, which carried Charles Darwin on his voyage round the world.
 Passage 3:He was the son of Henry Andrade Harben and the grandson of Sir Henry Harben who founded Prudential Assurance, Harben was educated at Eton College and Magdalen College, Oxford, before qualifying as a barrister. He married Agnes Helen Bostock. He stood unsuccessfully for the Conservative Party in Eye at the 1900 general election, but by 1902 had switched his affiliation to the Liberal Party. He stood for the Liberal Party in Worcester at the 1906 general election. Although he lost the election, he petitioned the election court on the grounds that supporters of the winner, George Henry Williamson, had engaged in widespread bribery. He won the case, but the seat was left vacant until a by-election in 1908, and the local Liberal Party adopted a new candidate. Harben next stood in Portsmouth at the December 1910 general election, but came bottom of the poll.

Example Input: Question: How many casualties combined where in the two wars where the Bofors 37 mm anti-tank gun gained most of its fame from? Passage 1:The Bofors 37 mm anti-tank gun was an anti-tank gun designed by Swedish manufacturer Bofors in the early 1930s originally for Swedish use. It was exported to several countries during the 1930's of which several bought licences to produce it themselves. The gun was used in several conflicts but most of its fame comes from its use in the Spanish civil war and the Winter war where it was used very successfully against light tanks and armored cars among other targets. Beyond its use as an infantry gun it was also used as the main armament in several armored cars and tanks such as the Dutch M39 Pantserwagen and the Polish 7TP to name a few. As the armor of tanks was increased during World War II the gun very quickly became obsolete as an anti-tank gun but was still used effectively as an infantry support gun for the entirety of the war, and well into the Cold War. This was due to its high fire rate, great mobility and effective high explosive shells.
 Passage 2:The Arcore was designed at the Centro Volo a Vela (CVV), or Experimental Soaring Centre, of the Royal Polytechnic of Milan by Gildo Preti. It was the third glider to be designed and built there and had a close resemblance to the first of them, the CVV 1 Pinguino. Both were wood and fabric single seat competition gliders, cantilever monoplanes with mid-mounted gull wings. The wings in particular were very similar in all respects apart from the Arcore's greater span. They were built around a single spar, with a plywood covered D-box ahead of it and fabric behind. In plan, they had a constant chord centre section, filling about a third of the span, and outer sections with taper on both leading and trailing edges ending in semi-elliptical tips. The centre section had positive dihedral but there was none on the outer panels. Ailerons occupied the whole of these outer panels, hinged parallel to the trailing edge. Short span airbrakes extended upwards only, mounted just behind the spar at the outer ends of the centre section.
 Passage 3:Noyes served on frontier duty at Fort Leavenworth, Kansas from November 1865 to June 1866, at Fort Riley, Kansas from June 1866 to March 13, 1867, at Fort Laramie, Dakota Territory from May 1 to November 1867, and at the newly established Fort D.
