Input: Consider Input: Question: How many soldiers died in the war that Charles K. Erwin fought in? Passage 1:The source of the river is Lake Hendricks on the boundary of Lincoln County, Minnesota, and Brookings County, South Dakota. It issues from the lake in Hendricks, Minnesota, and flows northeastwardly through northwestern Lincoln County as an intermittent stream on the Coteau des Prairies, a morainic plateau dividing the Mississippi and Missouri River watersheds, into western Yellow Medicine County, where it flows off the Coteau, dropping 250 feet (76 m) in eight miles (13 km). Continuing northeastwardly through flat till plains with occasional willows and cottonwoods along its banks, the river flows into eastern Lac qui Parle County, passing to the east of Dawson. It flows into the Minnesota River just below Lac qui Parle Lake in Lac qui Parle State Park, approximately ten miles (15 km) northwest of Montevideo, after flowing through a wooded valley in which it drops 210 feet (64 m) in 18 miles (29 km). Lac qui Parle Lake was formed by a delta at the mouth of the Lac qui Parle River, and is maintained by a dam.

Input: Consider Input: Question: How many championships have been won by the team Žigić turned professional with in 2003? Passage 1:Beginning in 1986, Warner Bros. moved into regular television animation production. Warners' television division was established by WB Animation President Jean MacCurdy, who brought in producer Tom Ruegger and much of his staff from Hanna-Barbera Productions' A Pup Named Scooby-Doo series (1988–1991). A studio for the television unit was set up in the office tower of the Imperial Bank Building adjacent to the Sherman Oaks Galleria northwest of Los Angeles. Darrell Van Citters, who used to work at Disney, would work on the newer Bugs Bunny shorts, before leaving to form Renegade Animation in 1992. The first Warner Bros. original animated TV series Tiny Toon Adventures (1990–1995) was produced in conjunction with Amblin Entertainment, and featured young cartoon characters based upon specific Looney Tunes stars, and was a success. Later Amblin/Warner Bros. television shows, including Animaniacs (1993–1998), its spin-off Pinky and the Brain (1995–1998), and Freakazoid! (1995–1997) followed in continuing the Looney Tunes tradition of cartoon humor.
 Passage 2:Ohloblyn traced his ancestry to the Novgorod-Siversky region of Left-bank Ukraine, which had formed an important part of the autonomous Ukrainian "Hetmanate" in the seventeenth and eighteenth centuries, and throughout his professional career as a historian retained a lively interest in this area and wrote frequently about it. Educated at the universities in Kiev, Odessa, and Moscow, from 1921 to 1933 he taught history at the Kiev Institute of People's Education (as Kiev University was known after the revolution), but during Joseph Stalin's purges, was dismissed from his posts, forced to recant his allegedly "bourgeois nationalist" views, and suffered repression including several months of imprisonment. In the late 1930s he returned to teaching at Kiev and Odessa universities. When the Germans occupied Kiev in the fall of 1941, Ohloblyn was appointed head of the Kiev Municipal Council, a post which he held from September 21 to October 25, and was a member of the Ukrainian National Council which tried to organize Ukrainian life under the difficult conditions of the occupation. He desperately tried to save from execution some of Jews he knew but the German commandant of Kiev informed him that "the Jewish issue belongs to exclusive jurisdiction of Germans and they will solve it at their own discretion" (, in Russian). Politics under the Nazis was not to his taste and he quickly retired from his public positions and returned to his scholarly work. In 1942 he worked as a director of Kiev Museum-Archive of Transitional Period, whose exhibition compared life under Bolsheviks and under Germans. In 1943 he moved to Lviv in western Ukraine and in 1944 to Prague. Upon the approach of the Red Army, he fled west to Bavaria. From 1946 to 1951, he taught at the Ukrainian Free University in Munich. In 1951, he moved to the United States where he was active in various Ukrainian emigre scholarly institutions such as the Ukrainian Academy of Arts and Sciences in the US and the Ukrainian Historical Association. From 1968 to 1970, he was a Visiting Professor of History at Harvard University.
 Passage 3:Žigić was born in Bačka Topola, in what was then SFR Yugoslavia. He began playing football as a youngster with AIK Bačka Topola, and scored 68 goals from 76 first-team matches over a three-year period in the third tier of Yugoslav football. Military service took him to Bar in 2001, where he was able to continue his goalscoring career with the local second-level club Mornar. A brief spell back in the third tier with Kolubara preceded his turning professional with First League side Red Star Belgrade in January 2003. He spent time on loan at third-tier Spartak Subotica before making his Red Star debut later that year. Despite suggestions that his height, of , made him better suited to sports other than football, Žigić ended the season as First League top scorer, domestic player of the year, league champion and scorer of the winning goal in the cup final. He won a second league–cup double in 2005–06, a second player of the year award, and finished his three-year Red Star career with 70 goals from 109 appearances in all competitions.

Input: Consider Input: Question: Did the professor Chamberlain studied under author any books? Passage 1:Chamberlain then went to Geneva, where he studied under Carl Vogt (a supporter of racial typology at the University of Geneva), Graebe, Müller Argoviensis, Thury, Plantamour, and other professors. He studied systematic botany, geology, astronomy, and later the anatomy and physiology of the human body. Under the tutelage of Professor Julius von Wiesner of the University of Vienna, Chamberlain studied botany in Geneva, earning a Bacheliers en sciences (BSc) physiques et naturelles in 1881. His thesis, Recherches sur la sève ascendante (Studies on rising sap), was not finished until 1897 and did not culminate in a further qualification. The main thrust of Chamberlain's dissertation is that the vertical transport of fluids in vascular plants via xylem cannot be explained by the fluid mechanical theories of the time, but only by the existence of a "vital force" (force vitale) that is beyond the pale of physical measurement. He summarises his thesis in the Introduction: Physical arguments, in particular transpirational pull and root pressure, have since been shown to be adequate for explaining the ascent of sap.
 Passage 2:Born at Devon, Jamaica, where he was taught cricket by the manager of a banana plantation and once played in a match featuring George Headley. Gibson moved to England in 1944, accompanied by a friend, where he joined the Royal Air Force and saw service in the later stages of World War II while stationed near Melton Mowbray in Leicestershire. Following the war, Leicestershire County Cricket Club secretary Cecil Wood was given the task of building a team for the resumption of first-class cricket, with Gibson impressing Wood in friendly one-day matches against Northamptonshire and Nottinghamshire in 1945. He was offered the chance to play for Leicestershire in 1946, making two first-class appearances against Yorkshire in the County Championship at Headingley and Oxford University at the University Parks. He scored a total of 17 runs in his two matches, at an average of 5.66, with a high score of 11. He suffered arm and head injuries in a car accident midway through the 1946 season and was not reengaged by the county.
 Passage 3:The Lakers were founded as the Detroit Gems in 1946 before relocating to Minneapolis, Minnesota and renaming themselves the Lakers (Minnesota's nickname is "The Land of 10,000 Lakes"). The club won several titles led by center George Mikan in the 1950s before moving to Los Angeles in 1960. In 1972 they won another championship led by center Wilt Chamberlain and point guard Jerry West. After acquiring center Kareem Abdul-Jabbar in 1975 and point guard Magic Johnson in 1979, the Lakers built a team that won 5 titles in the 1980s. With the retirement of Johnson and Abdul-Jabbar, they struggled in the 1990s. However, in 1996 the club acquired free agent center Shaquille O'Neal and traded with the Charlotte Hornets for newly drafted shooting guard Kobe Bryant. With the two maturing under coach Phil Jackson, the club turned into a contender in the early 2000s.
