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.
 Passage 2:Born in Washington, Lycoming County, Pennsylvania, Erwin settled in Portage, Wisconsin in 1853. From 1855 to 1868, Erwin lived in Jo Daviess County, Illinois and then in Stephenson County, Illinois. During the American Civil War, Erwin served in the 45th Illinois Volunteer Infantry Regiment. In 1868, Erwin moved to Tomah, Wisconsin and was in the mercantile business. From 1879 to 1882 and 1886, Erwin served on the Tomah Board of Education and was president of the school board. From 1882 to 1889, Erwin served in the Wisconsin State Senate and was a Republican. In 1889, Erwin served as postmaster for Tomah, Wisconsin. In 1902, Erwin moved with his family to Milwaukee, Wisconsin. Erwin died suddenly in Savanna, Illinois just as he was about get on a train for a trip to Omaha, Nebraska.
 Passage 3:During the 2006/07 season, Liang reached at least the second round of qualifying in every ranking event. At the Northern Ireland Trophy, he beat Robert Stephen 5–0 before falling to David Gilbert 0–5 in qualifying.

 Passage 2:Other examples of mostly locally generated historical markers in the United States include the plaque outside the Alaska Governor's Mansion made by the Alaska Centennial Commission's historical markers program, the historical markers of State Historic Marker Council in Florida, the markers placed by various agencies in Georgia (of which one source mentions 3,292 different historical markers), in Indiana, where it is illegal to create a historical marker in the "state format" without first getting official approval from that state's historical bureau, historical markers in Kansas erected by the Kansas Historical Society and the Kansas Department of Transportation, the Roadside Historic Marker Program in Maryland administered by the Maryland Historical Trust, the State Historic Marker Program of New York (begun in 1926 to commemorate the Sequicentennial of the American Revolution), the historic markers placed as recently as 2008 in Sussex County, New Jersey, the New Mexico historical markers printed in white letters on a brown background by the New Mexico Department of Transportation, the historical markers of North Carolina (the Historical Publications Section of the state Office of Archives and History publishes a Guide to North Carolina Highway Historical Markers), the more than 1200 historical markers of Ohio (all of which are now made in a Marietta, Ohio workshop), and over 550 official state markers in Wisconsin.
 Passage 3:In Brisbane they soon became known for their unique shows, experimentation and friendliness. After some initial hardships, McSweeney soon found like-minded musicians in Josh Engelking (percussion), Bo Whitton (bass guitar), Ellen Stancombe (violin) and Wayne Jennings (cello). The newly formed lineup soon released the "Rain" single. Based on the single and performances, McSweeney soon began to feature heavily in local media, becoming known for his revolutionary views on music, eccentric interviews/performances and the influence of his colour synesthesia on his music and art. In 2006 the band conducted two extensive national tours, including sets at the coveted Livid and Big Day Out festivals. Following this success, a live performance was recorded with Brisbane community radio station 4ZZZ FM and was released in 2004 as the album The Virgin Mary Australian Tour Acoustic/Strings Album, which received yet more positive feedback. They also headlined the 2004 Valley Fiesta, and played support for Australian singer–songwriter Missy Higgins. 2005 saw the band conduct a two-week tour of China, and release the Walls EP with Modern Music/Sony BMG to critical acclaim. The EP received high rotation play on the national Triple J radio station and generated plenty of new fans. The title track, "Walls", entered the stations "Net 50" chart at #3 and charted for fifteen weeks. Sometime around this release bass player Bo Whitton left the band and was replaced by Amanda Holmes.

Question: What was the age of Lea Sirk the year that she placed twenty-second in the Eurovision Song Contest? Passage 1:Morton was a prolific photographer who took photographs of all aspects of life in North Carolina. His first published photograph came in 1935, when he was 14; a picture he took of a golfing scene was published as a North Carolina travel advertisement in Time Magazine. During his time at the University of North Carolina, he was a photographer for the student newspaper, the Daily Tar Heel. During World War II, Morton joined as a member of the Signal Corps, where he was assigned the job of newsreel photographer. He was sent to New Caledonia, an island off the coast of Australia, where he was attached to the 37th Infantry Division. Near the end of the war, Morton was assigned to take pictures of General Douglas MacArthur when MacArthur's regular photographer was sick. While on the island of Luzon in the Philippines, Morton was injured by a Japanese explosive and was awarded the Bronze Star and the Purple Heart.
 Passage 2:A solar cell, or photovoltaic cell (PV), is a device that converts light into electric current using the photovoltaic effect. The first solar cell was constructed by Charles Fritts in the 1880s. The German industrialist Ernst Werner von Siemens was among those who recognized the importance of this discovery. In 1931, the German engineer Bruno Lange developed a photo cell using silver selenide in place of copper oxide, although the prototype selenium cells converted less than 1% of incident light into electricity. Following the work of Russell Ohl in the 1940s, researchers Gerald Pearson, Calvin Fuller and Daryl Chapin created the silicon solar cell in 1954. These early solar cells cost US$286/watt and reached efficiencies of 4.5–6%. In 1957, Mohamed M. Atalla developed the process of silicon surface passivation by thermal oxidation at Bell Labs. The surface passivation process has since been critical to solar cell efficiency.
 Passage 3:Prior to the 2020 Contest, Slovenia had participated in the Eurovision Song Contest twenty-five times since its first entry in . Slovenia's highest placing in the contest, to this point, has been seventh place, which the nation achieved on two occasions: in 1995 with the song "Prisluhni mi" performed by Darja Švajger and in 2001 with the song "Energy" performed by Nuša Derenda. The country's only other top ten result was achieved in 1997 when Tanja Ribič performing "Zbudi se" placed tenth. Since the introduction of semi-finals to the format of the contest in 2004, Slovenia had thus far only managed to qualify to the final on six occasions. In 2018, Slovenia was represented by Lea Sirk and the song "Hvala, ne!", which qualified to the final and placed twenty-second. One year later, in 2019, Slovenia qualified for the final again with Zala Kralj & Gašper Šantl, finishing in fifteenth place with the song "Sebi".
