Example Input: Question: How long has Nakayama been president of Sega when he was looking for a flagship series to compete with Mario? Passage:In 1990, Sega president Hayao Nakayama sought a flagship series to compete with Nintendo's Mario franchise along with a character to serve as a company mascot. Several character designs were submitted as part of a contest. Among the designs was an egg-shaped man wearing pajamas who resembled Theodore Roosevelt, drawn by Naoto Ohshima. According to Ohshima, the resemblance to Roosevelt was unintentional, saying he was influenced by a variety of characters. Retrospective sources have indicated Ohshima based the character on Humpty Dumpty and Mario. The Roosevelt lookalike did not win the contest; rather, another Ohshima character, a hedgehog named Mr. Needlemouselater renamed Sonicprevailed. As development of the Sega Genesis game Sonic the Hedgehog progressed, however, programmer Yuji Naka and the rest of Sonic Team thought the rejected design was excellent and deserved inclusion in the game. Since the character could not be the protagonist, the team retooled him into the game's main antagonist.

Example Input: Question: Is the bridge that was slated to begin reconstruction in 2014 complete? Passage:SR162 was codified as SSH5E during the creation of the primary and secondary state highways in 1937, beginning at Primary State Highway5 (PSH5) and U.S. Route410 in Puyallup, traveling through Orting and South Prairie to end at an intersection with a branch of PSH5 southwest of Buckley. SSH5E had a branch that traveled south from Orting to Electron that was removed from the state highway system in 1955. The highway traveled across the Puyallup River into Orting on the McMillin Bridge, which opened in 1934 as a concrete half-through truss bridge to save the Department of Highways a total of $826. SR165 was established during the 1964 highway renumbering and was codified in 1970 as the replacement to SSH5E. The western terminus, now at SR410, was moved east to an interchange in Sumner after the completion of the Sumner Freeway in 1972. The McMillin Bridge was added to the National Register of Historic Places in 1982 as an example of a half-through truss bridge built with concrete instead of steel. The route of the highway has not seen a major revision since 1972; however, WSDOT repaved the roadway and added guardrails between Orting and Buckley in 2008. The deteriorating McMillin Bridge is being replaced by WSDOT with a newer, wider span over the Puyallup River scheduled to begin construction in 2014.

Example Input: Question: How many soldiers did Britain send to World War I the year Roebuck arrived on the Western Front? Passage:As a boy, Roebuck worked as a trammer and after being sentenced to one month's imprisonment for stealing a watch in 1904, he enlisted in the York and Lancaster Regiment. Over the next seven years, he was stationed in India and Ireland and was promoted to lance corporal, but was demoted back to private in 1910 for "misconduct". He married in 1908 and had two children. Roebuck was discharged into the reserves in 1912 and likely returned to work as a miner prior to becoming a professional footballer in 1913. After Britain's entry into the First World War in August 1914, he was called up by the York and Lancaster Regiment and arrived on the Western Front in September 1914. On 18 October 1914, Roebuck recorded as "presumed dead" after an attack near Beaucamps-Ligny during the Race to the Sea. His death was confirmed by two comrades in January 1915. Roebuck is commemorated on the Ploegsteert Memorial to the Missing.
