Example Input: Question: In which country was MS Al Andalus Express built? Passage 1:MS Al Andalus Express (formerly Nord Pas-de-Calais) is a freight ferry owned by Eurotunnel and operated by FRS Iberia/Maroc. She was built in 1987 by Chantiers du Nord et de la Mediterranee, Dunkirk (Yard No 325) for Societe Nationale des Chemin de Fer Francais (SNCF), Paris as a multi-purpose passenger and roll-on roll-off ferry for lorries and railway vehicles. After the introduction of Eurotunnel there was no need for a train ferry, so SNCF was losing money running her. She was acquired by SNAT and Stena Sealink in 1989, which operated the Nord Pas-de-Calais until 31 December 1995. From 1 January 1996 SNAT operated as SeaFrance. The vessel was renamed SeaFrance Nord Pas-de-Calais. SeaFrance operated until November 2011, and was liquidated on 9 January 2012. Eurotunnel won the bid for the three of the former SeaFrance vessels the original name of the vessel was restored, dropping the SeaFrance prefix. MyFerryLink started running on 20 August 2012, although Nord Pas-de-Calais joined in November 2012 following a refit. Following MyFerryLink's cessation of operations, mostly cited due to financial issues, the ferry was used directly by Eurotunnel to carry hazmat cargoes that are not allowed on regular train services.
 Passage 2:Lange was born in Warsaw into the patriotic Jewish family of Henryk Lange (1815–1884) and Zofia née Eisenbaum (1832–1897). His father took part in the November Uprising against the Russian Partition of Poland. He was an admirerer of Romantic literature and its ideals. Antoni Lange enrolled at Warsaw University but around 1880 he was expelled for his patriotic activity by the Tsarist namiestnik Apuchtin who ruled the university at that time. He supported himself financially as a tutor but also published poetry under the pen-names Napierski and Antoni Wrzesień. He decided to study in Paris where he encountered new trends in literature, philosophy and art. In France he became familiar with the theories of Jean Martin Charcot, as well as Spiritualism, parapsychology, the philosophy of Arthur Schopenhauer and Friedrich Nietzsche, oriental religions, European and Eastern literature and modern literary criticism. He took part in the literary meetings of Stéphane Mallarmé.
 Passage 3:Bulgaria was focused on actions in Thrace and Macedonia. It deployed its main force in Thrace, forming three armies. The First Army (79,370 men), under general Vasil Kutinchev with three infantry divisions, was deployed to the south of Yambol, with direction of operations along the Tundzha river. The Second Army (122,748 men), under general Nikola Ivanov, with two infantry divisions and one infantry brigade, was deployed west of the First and was assigned to capture the strong fortress of Adrianople (Edirne). According to the plans, the Third Army (94,884 men), under general Radko Dimitriev, was deployed east of and behind the First, and was covered by the cavalry division hiding it from Turkish view. The Third Army had three infantry divisions and was assigned to cross the Stranja mountain and to take the fortress of Kirk Kilisse (Kırklareli). The 2nd (49,180) and 7th (48,523 men) divisions were assigned independent roles, operating in Western Thrace and Eastern Macedonia respectively.

Example Input: Question: Is the racing team who took over Andy Rouse's Ford team in 1996 still in operation? Passage 1:Fearing that his self-proclaimed sex appeal with women was being threatened by Morton, NWA Champion Ric Flair began a feud with Morton in 1986. In the spring of that year, Morton was having an interview at ringside when Flair came onto the set and insulted Morton's fans (who consisted mostly of tween girls) by calling them "teenyboppers in their training bras." He gave Morton a training bra as a "gift from one of Flair's girlfriends" and told Morton that he couldn't handle real, grown-up women. In response, Morton stomped on Flair's sunglasses. This led to a fight and then a series of matches, the most notable being their Steel Cage match at the 1986 Great American Bash. To help build Morton as a serious title contender, it was pointed out that he once went to a one-hour draw with then-AWA Champion Nick Bockwinkel. Morton never won the title but he proved that he was of the same caliber as Flair was in the ring. At one point in the feud with Flair, after a six-man tag team elimination match in which Morton pinned Flair to become the winner, Flair and the other three Four Horsemen invaded the Rock 'n' Roll Express' dressing room and attacked Morton, rubbing his face on the concrete floor, causing a grotesque-looking facial injury. They also broke his nose in another attack. Horsemen member Arn Anderson would also make fun of Morton, calling him "Punky Morton," which was a play on the popular 1980s sitcom Punky Brewster. The term used to belittle Morton backfired when fans began to use it as a term of endearment. Morton and Gibson won the title back from the Midnight Express and feuded with Ole and Arn Anderson for the rest of the year. They culminated this feud with a win over the Andersons in a cage match at Starrcade on November 28. This victory started the Horsemen's dissatisfaction with Ole, who was kicked out of the stable just months later. Morton and Gibson then lost the title to Rick Rude and Manny Fernandez on December 6, 1986, whom they feuded with from December 1986 to June 1987. When Rude left for the World Wrestling Federation, the title was given back to the Rock & Roll Express, with the explanation that they won the title accompanied by footage of a prior non-title match won by the Rock & Roll Express where they pinned the champions.
 Passage 2:Kevin Steen (born May 7, 1984) is a Canadian professional wrestler. He is currently signed to WWE, where he performs on the Raw brand under the ring name Kevin Owens. He began his career in 2000 at the age of 16. Prior to joining WWE in late 2014, from 2007, Steen wrestled under his birth name for Ring of Honor (ROH), where he held the ROH World Championship and ROH World Tag Team Championship. Steen also wrestled extensively on the independent circuit for 14 years, most notably in Pro Wrestling Guerrilla (PWG), where he held the PWG World Championship a record three times, as well as the PWG World Tag Team Championship on three occasions.
 Passage 3:He won the 1993 and 1994 Touring Car World Cup events at Monza and at Donington respectively. 1993 was his first British Touring Car Championship (BTCC) season, in a Ford Mondeo prepared by Andy Rouse. He finished 3rd in the series despite only competing in half the year. He would again drive for Andy Rouse in 1994 where he finished 3rd again behind Gabriele Tarquini for Alfa Romeo and Alain Menu for Renault. Radisich would again drive for Andy Rouse in 1995 but by the end of the 1995 season the car had reached the end of its development cycle and was increasingly uncompetitive during the end of the 1995 season and in the 1996 season when West Surrey Racing took over the Ford team from Andy Rouse. 1996 would be a disappointment for the Ford team with no podium places and Radisich finishing 13th in the championship. 1997 would see a new Mondeo however it to was uncompetitive and would not challenge the front running teams. In 1998 he raced for Peugeot where he again had a disappointing season. He left the series and went to race for Dick Johnson Racing in the V8 Supercar series in Australia.

Example Input: Question: What is the population of the city where De Leon lost his title in 1982? Passage 1:Initially intending to go into medicine, Smith became interested in biology and organic chemistry during his second year at Columbia University. He earned a B.S. in 1931 and stayed at Columbia to study photosynthesis under Selig Hecht, completing a Ph.D. in biophysics in 1936. In 1938, he went to Cambridge University on a Guggenheim Fellowship to work with David Keilin on the chlorophyll-protein complex. Upon returning to the U.S. during World War II, he took a position at Yale University's Connecticut Agricultural Experiment Station to work with Hubert Bradford Vickery. He joined the lab of eminent protein chemist Max Bergmann at the Rockefeller Institute in 1940, where he worked with a number of important biochemists and began a significant line of research on the intestinal enzyme erepsin.
 Passage 2:De León, a native of Trujillo Alto, Puerto Rico, first won a world title when faced with WBC world champion Marvin Camel on November 25, 1980, at the undercard of Sugar Ray Leonard and Roberto Durán's second fight in New Orleans. De León outpointed Camel over 15 rounds. After he knocked out Camel in 8 in a rematch, countryman Ossie Ocasio won the WBA world title, becoming the second pair of Puerto Ricans to share world titles in the same division at the same time, after Alfredo Escalera and Samuel Serrano had achieved the feat in the 1970s at Jr. Lightweight. De León lost his title in a shocking upset to former Gerry Cooney victim S. T. Gordon by a knockout in round 2 at Cleveland in 1982, and won a comeback fight versus former world Heavyweight champion Leon Spinks by a knockout in round six in 1983. After that, he and Gordon boxed a rematch in Las Vegas, and De León dropped Gordon once in the first round and once in the twelfth, en route to a unanimous decision win in a history-making bout: De León had now become the first boxer to win the world Cruiserweight title twice.
