Example Input: Question: How many championships had Lawson's archrival and later teammate win? Passage 1:When the Northern Yuan Chahar Borjigin Mongol Khan Ejei Khan surrendered to the Qing, he was given the title of Prince of the first rank (Qin Wang, 親王), a title he held until his death in 1661, and inherited by his younger brother Abunai (阿布奈). Abunai openly showed his discontent toward the Manchu and he was put under house arrest in Shenyang by the Kangxi Emperor in 1669 and his imperial title / rank was given to his son Borni (布尔尼) in September of that same year. Borni (布尔尼) was careful to not show any sign of disrespecting the Qing Dynasty, but finally in 1675, he suddenly rebelled along with his younger brother Lubuzung (罗布藏), capitalizing on the Revolt of the Three Feudatories. However, they had made a serious miscalculation in wrongfully believing that other Mongols would join them, when in reality only three thousand Chahar (Mongols) joined the rebellion. It only took a single decisive battle on April 20, 1675 to defeat Abunai (阿布奈) and his followers, who were all killed subsequently in their retreat. The Qing Dynasty's punishment of the rebellion was very harsh: all royal males of Chahar (Mongols) were executed, including infants born to Qing / Manchu princesses, and all royal females of Chahar (Mongols) were sold to slavery except these Qing / Manchu princesses.
 Passage 2:In 1967 at the start of the governorship of Ronald Reagan one of Reagan's first actions was to fire Nelson from her state government post at the Consumer Counsel. Nelson said that this was because she was disliked by Reagan's supporters, including the California Grocer's Association and the California Manufacturers' Association. After this she became elected president of the Consumer Federation of California. She served also on the board of Consumers Union, and would be re-elected for a total of five three-year terms on that board. From 1969-1979 served as a professor of economics at the University of Wisconsin. During this time she also served as a public governor for the American Stock Exchange. In 1968 after 15 years of work her lobbying had contributed to the passing of the Truth in Lending Act. She served two terms as president of the Consumer Federation of America from 1972-1982. She was the consumer consultant to the Office of Technology Assessment and the National Academy of Science. She petitioned the National Academy of Science to recognize the research showing saccharin as a cancer-causing agent and fluorocarbons as causing ozone depletion. In 1978 President Jimmy Carter appointed Nelson to the President's Export Council. Also in 1978 the American Council on Consumer Interests recognized her as a "Distinguished Fellow". In 1979 after the 1977 death of her husband Nelson returned to Mill Valley, California. There she was appointed to the Consumer Advisory Council of the Federal Reserve Board of Governors, the consumer advisory panel for Pacific Bell, and the San Francisco chapter of Consumer Action. At this time she said that her worst fear for the future was "That consumers will become like the feudal people of old times. That they will be so tied to a VISA card that they are not whole people. That they will be easily manipulated by the television and sellers, that they will do what is suggested to them instead of what comes from their own spirit."
 Passage 3:Lawson accepted an offer from Yamaha to contest the 500cc World Championship as Kenny Roberts' teammate for the 1983 season. Lawson spent the 1983 season learning the ropes of the Grand Prix circuit. In 1984, Lawson began winning regularly and won the 1984 World Championship. It would mark the first of four world titles Lawson would go on to win. In 1985, he won the prestigious Imola 200 pre-season race. After winning two more titles for Yamaha in 1986 and 1988, Lawson shocked the racing world by announcing he would be leaving Yamaha to sign with their arch-rivals Rothmans Honda as teammate to his own archrival, Australia's 1987 World Champion Wayne Gardner. By switching teams, Lawson also fulfilled his desire to work with Erv Kanemoto. After Gardner crashed and broke his leg during the third round at Laguna Seca, Lawson went on to win the 1989 title for Honda, becoming the first rider to win back-to-back championships on machines from different manufacturers. By winning with both Yamaha and Honda, Lawson silenced his critics who believed he would not be as successful away from the factory Marlboro Yamaha team.

Example Input: Question: How long had Alycia Lane been working at KNBC when she left the station? Passage 1:The last meetings had revealed the rising antagonism with Britain and France, especially on Italian unification, the right to self-determination and the Eastern Question. The Alliance is conventionally taken to have become defunct with Alexander's death in 1825. France ultimately went her separate way after the July Revolution of 1830, leaving the core of Russia, Austria and Prussia as Central-Eastern European block which once again congregated to suppress the Revolutions of 1848. The Austro-Russian alliance finally broke up in the Crimean War: though Russia had helped to completely destroy the Hungarian Revolution of 1848, Austria did not take any action to support her ally, declared herself neutral and even occupied the Wallachian and Moldavian lands on the Danube upon the Russian retreat in 1854. Thereafter, Austria remained isolated, which added to the loss of her leading role in the German lands, culminating in the defeat of the Austro-Prussian War in 1866.

Example Input: Question: How much before the IXB submarines came out did the IX submarines come out? Passage 1:Vranica is a mountain range in the Dinaric Alps of central Bosnia and Herzegovina, located between the town of Gornji Vakuf in the west and the town of Fojnica in the east, within the territory of the Federation. The highest peak is Nadkrstac at . Geologically, the Vranica range is part of the Dinaric Alps and formed largely of secondary and tertiary sedimentary rock, mostly limestone. Notable peaks are Nadkrstac (2110 m.), Locika (2106 m.), Rosinj (2059 m.) and Scit (1949 m.). Thick shrubs of Pinus Mugo replace mixed forest -mostly beech- above 1400 m.

Streams that source from these mountains are the Dragača in the east, the Vrbas in the west. 
 Passage 2:The Rams turned in a dominant performance over the NFC West rival Cardinals at London's Twickenham Stadium for their first-ever regular season victory outside the United States. Jared Goff threw for 235 yards and had a touchdown pass to Cooper Kupp (four receptions, 51 yards), with one interception. Goff also scored on a 9-yard run as the Rams built a 23-0 halftime lead. Todd Gurley had his fourth 100-yard rushing game of the season with 22 carries for 106 yards and a touchdown, plus four receptions for 48 yards.
