Example Input: Question: What city did Stevens complete a Ph.D. in? Passage 1:The siblings were born in New Haven, Connecticut, and moved to Downey, California, in 1963. Richard took piano lessons as a child, progressing to California State University, Long Beach, while Karen learned the drums. They first performed together as a duo in 1965 and formed the jazz-oriented Richard Carpenter Trio followed by the middle-of-the-road group Spectrum. Signing as Carpenters to A&M Records in 1969, they achieved major success the following year with the hit singles "(They Long to Be) Close to You" and "We've Only Just Begun". Subsequently, the duo's brand of melodic pop produced a record-breaking run of hit recordings on the American Top 40 and Adult Contemporary charts, and they became leading sellers in the soft rock, easy listening and adult contemporary music genres. The Carpenters had three number-one singles and five number-two singles on the Billboard Hot 100 and fifteen number-one hits on the Adult Contemporary chart, in addition to twelve top-10 singles. They have sold more than 90 million records worldwide, making them one of the best-selling music artists of all time. The duo toured continually during the 1970s, which put them under increased strain; Richard took a year off in 1979 after he had become addicted to Quaaludes, while Karen suffered from anorexia nervosa.
 Passage 2:In 1980, Stevens joined the Army under their split option training program and conducted basic training at Fort Dix, New Jersey and advanced individual training at Fort Sam Houston, Texas. While engaged in his military service, Stevens entered the University of Southern Maine in the Computer Science program in 1981. However, an enthusiastic professor (John Ricci) converted him to the study of Chemistry. He spent two summers working as an intern at the Brookhaven National Laboratory in Long Island with Professor Ricci, and Drs. Thomas Koetzle and Dick McMullan, where he first learned how to determine the molecular structure of compounds by X-ray and neutron diffraction. While there he also met a University of Southern California research team led by Dr. Robert Bau; after he obtained a Bachelor of Science degree in Chemistry at USM, he entered the University of Southern California in pursuit of a Doctor of Philosophy degree in Chemistry working with Professor Robert Bau and Nobel Laureate Professor, George Olah. He completed his Ph.D. in 26 months, graduating in 1988.
 Passage 3:The 1966 NASCAR season opened at Augusta Speedway on November 14, 1965, with Richard Petty winning the season opening event in a 1965 Plymouth. NASCAR then ventured to Riverside International Raceway where Dan Gurney took the checkered flag in a 1965 Ford. After the January 23rd Riverside event, the drivers and teams traveled to Daytona International Speedway in Florida for the 1966 Daytona 500. Paul Goldsmith and Early Balmer took the qualifying events, while Richard Petty notched his first and only Daytona 500 pole position. Petty came from two laps down during the competition to win by more than a full lap when the race was halted 2 laps shy of scheduled event due to thunderstorms. In March Paul Goldsmith won at Rockingham Speedway, Dick Hutcherson at Bristol, and Jim Hurtubise captured the checkered flag at Atlanta Motor Speedway. Hutcherson's victory at Bristol was by more than 4 laps over the closest competitor, Paul Lewis, when crashes and attrition left only seven cars of the 38 starters running at the end of the Southeastern 500 (now known as Food City 500). On April 3, Pearson finally found his way to victory lane in the first of four consecutive victories at Hickory Motor Speedway. He followed up with wins at Columbia Speedway, Greenville, and Winston-Salem, before Jim Paschal broke his streak at North Wilksboro and repeated at Martinsville Speedway. On May 7, Richard Petty started a string of three consecutive wins at Darlington Raceway, Hampton, and Macon. After Ford's announcement of their boycott of NASCAR on April 7, only 2.500 fans attend the May 13th event in which Darel Dieringer captures the win at Monroe in a contest.

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.
 Passage 2:Early in her career, she worked with the Univision network in Miami, Florida. She moved to Telemundo-owned station KTMD in Houston, Texas, from 2004 until she joined NBC-affiliated station KPRC-TV as a general assignment reporter and weekend anchor in 2006. Known for her dynamic reporting, she has covered many prominent news stories, including Hurricanes Ike, Dolly and Gustav. She was one of the first reporters on the scene to cover the 2009 Fort Hood shooting. In 2012, she was named co-anchor of WMAQ-TV's weekday morning newscasts along with Stefan Holt, replacing Rob Elgas and Zoraida Sambolin, who returned to the station in 2014. In June 2014, Guzman joined KNBC in Los Angeles as a co-anchor of Today in L.A. alongside Whit Johnson after Alycia Lane left the station in 2013. In May 2016, L.A. Parent Magazine hired Daniella as a contributor to the magazine, the magazine debuts its column "On The Record: Straight Talk For Moms" in which, she is now also a magazine contributor in addition to its anchor duties at KNBC.
 Passage 3:She was born in the Kaʻū district of the Island of Hawaiʻi, to Mary Paʻahana Kanakaʻole (a native Hawaiian woman) and Henry Nathaniel Wiggin (originally from Massachusetts). In the traditional custom of hānai, she was initially reared by her mother's parents. Her grandmother Naliipoʻaimoku, a traditional dancer in the court of Queen Emma, taught her chants and stories, while her grandfather Keli'ikanaka'ole-o-Haililani (k) was a healer and kahuna pale keiki (obstetrician) who used lomilomi massage, laʻau lapaʻau (herbal medicine), hoʻoponopono (forgiveness), and pule (prayer). Her great grandmother Keliʻipaʻahana was a kahuna pule (priestess) in the Pele line. Keli'iPa'ahana's parents were the High Chief KU or Kauhi and High Chiefess Na'ai Hunali'i (The Hidden chief). Keli'iPa'ahana was interned in Halema'uma'u in 1869 in the Ka'u district. She married the High Chief Keli'iKanaka'ole (k) the son High Chief Kaelele and Princess Kekelaokalani. Family is known to inherit the sacred Ali'i Moe Kapu (the prostrating Taboo). Upon the death of her grandmother Nali'i Poai moku she returned to live with her parents and spoke both Hawaiian and English.

Example Input: Question: When was the only team Porto lost against in its group in the 2003–04 UEFA Champions League founded? Passage 1:He was promoted to lieutenant on 23 January 1962, captain on 23 July 1966, and major on 31 December 1972, At this time he was brigade major at HQ 3rd Infantry Brigade in Northern Ireland. As such he was responsible for the efforts to find Captain Robert Nairac who had been abducted by the Provisional IRA. Nairac and Jones had become friends and would sometimes go to the Jones household for supper. After a four-day search, the Garda Síochána confirmed that Nairac had been shot and killed in the Republic of Ireland after being smuggled over the border. On 13 December 1977 he was appointed a Member of the Order of the British Empire (MBE) for his services in Northern Ireland that year. On 30 June 1979 he was promoted lieutenant colonel, and on 1 December 1979, he was transferred to the Parachute Regiment. In the 1981 New Year Honours he was appointed an Officer of the Order of the British Empire (OBE).
 Passage 2:The 2003–04 season began with another 1–0 win over União de Leiria, which gave the club its 13th Supertaça. Weeks later, Porto failed to repeat this result in the 2003 UEFA Super Cup, losing 1–0 to Milan. The departure of striker Hélder Postiga was compensated by the signing of South Africa's Benni McCarthy, whose 20 league goals helped Porto in its league title defence and crowned him the competition's top scorer. Mourinho entered the 2003–04 UEFA Champions League with confidence to his team. Porto finished second in its group, losing only once to Real Madrid, and advanced to a round-of-16 meeting with Manchester United. Porto scored on the 90th minute of the second leg at Old Trafford to draw 1–1 and advance to the quarter-finals with a 3–2 aggregate win. The team then overcame Lyon and Deportivo La Coruña and reached the Champions League final, where it defeated Monaco 3–0 to lift the club's second European Champion Clubs' Cup. A 2–1 loss to Benfica in the Taça de Portugal final, held 10 days before, prevented another treble-winning season.
 Passage 3:He has been a professor at Princeton since 1975, following a leave from his professorship at MIT. Lieb has been awarded several prizes in mathematics and physics, including the 1978 Heineman Prize for Mathematical Physics of the American Physical Society and the American Institute of Physics (1978), the Max Planck Medal of the German Physical Society (1992), the Boltzmann medal of the International Union of Pure and Applied Physics (1998), the Schock Prize (2001), and the Henri Poincaré Prize of the International Association of Mathematical Physics (2003). Lieb is a member of the U.S. National Academy of Sciences and has twice served (1982–1984 and 1997–1999) as the President of the International Association of Mathematical Physics. Lieb was awarded the Austrian Decoration for Science and Art in 2002. In 2012 he became a fellow of the American Mathematical Society and in 2013 a Foreign Member of the Royal Society.
