Input: Consider Input: Question: What country were US tanks still rolling toward in March of 2003? Passage 1:Wilson was the son of Alexander Robertson Wilson, writer (or solicitor) and town clerk of the then Royal and Ancient Burgh of Irvine, and Elizabeth Wylie Murray. He was born in Irvine. He was named for a great-grandfather, John Gray, who was town clerk of Ayr, and joint secretary of the first Burns festival there in 1844; an uncle 'John Gray Wilson' had died at the age of 14. The John Gray Wilson of this article, the Sheriff, was educated at Irvine Royal Academy; the Edinburgh Academy, where he was Dux (leading scholar) in 1935; and, as an Open Classics Scholar, at Oriel College, Oxford where he graduated B.A.. In the long vacation of 1936 he contracted polio, which left him with a weakened leg and chest, and contributed to his early death. (At the time of this enforced absence, his name was used by a fantasist claiming to have been an aviator during the Spanish Civil War.) After Oxford, he attended Edinburgh University where he received the degree of Bachelor of Laws. In 1943 he married Nan MacAuslan, herself active in the liberal Party and later awarded a PhD by the University of Edinburgh for a Thesis on the Social Anthropology of the Faculty of Advocates. They had three sons.
 Passage 2:MEED was launched in 1957. When Rafiq Hariri drew up plans to rebuild a war-shattered Lebanon, MEED met the prime minister and asked him to explain them. When Colonel Gaddafi unveiled the first part of his Great Manmade River, MEED took a front-row seat at the ceremony and quizzed the engineers. While US tanks were still rolling towards Baghdad in March 2003, MEED obtained plans from Washington that described how the US was hoping to rebuild the country. Three months before going public, MEED revealed DP World's IPO plans. Abdalla el-Badri announced Opec's potential move from US dollar to euro pricing to MEED. MEED broke news of Saudi Arabia moving ahead with plans for a Mile-High Tower in Jeddah – which would make it the tallest tower in the world – and Nakheel's plans to create a tower over one kilometre high (then called Nakheel Tower, later announced as Dubai's Harbour Tower) to trump Emaar's Burj Khalifa.
 Passage 3:Balsdon skips one of the top teams in Ontario. As of 2019, Balsdon has played in 13 provincial championships. He first played at the provincials in 1999, playing for John Base (4th place). He left the Base rink in 2000 to form his own team. He qualified again in 2002 as a skip, again finishing 4th. His next provincial was the 2005 Ontario Kia Cup, where his rink finished 4th once again. He qualified again in 2007, where he once again finished 4th at the 2007 TSC Stores Tankard. His next provincial in 2011 would be more successful. At the 2011 provincial championship, he lost to the (then) five-time defending champion Glenn Howard rink in the final. At the time, Balsdon represented the one-sheet Loonie Curling Club located in Chaffeys Locks, Ontario, north of Kingston. Despite representing the club, he had only played there once. The Loonie was built in 2008, and Balsdon has represented it twice. Balsdon returned to the Tankard in 2012, finishing tied for 8th. Despite battling an injury for much of the season, Baldson won his first provincial men's title in 2014, when his rink defeated Glenn Howard in the Ontario final. The win broke Howard's record eight-year provincial championship streak. The team was named after third Mark Bice who had skipped the team through zone and regional play due to Baldson recovering from a broken rib. However, Balsdon would skip the team in the provincial championship. The team represented Ontario at the 2014 Tim Hortons Brier, where they went 5-6 in the round robin, missing the playoffs. The following season, at the 2015 Ontario Tankard, Balsdon and his rink lost in a tie breaker. Following the season, the team broke up.

Input: Consider Input: Question: Were Caton and Beck both from Poland? Passage 1:His article about the dullness of grammar school readers in a 1954 issue of Life magazine, "Why Do Students Bog Down on First R? A Local Committee Sheds Light on a National Problem: Reading" was the inspiration for Dr. Seuss's juvenile story The Cat in the Hat. Further criticisms of the school system came with The Child Buyer (1960), a speculative-fiction novel. Hersey also wrote The Algiers Motel Incident, about a racially motivated shooting by police during the 12th Street Riot in Detroit, Michigan, during July 1967. Hersey's first novel A Bell for Adano, about the Allied occupation of a Sicilian town during World War II, won the Pulitzer Prize for the Novel in 1945, and was adapted into the 1945 movie A Bell for Adano directed by Henry King, featuring John Hodiak and Gene Tierney. His 1956 short novel, A Single Pebble is the tale of a young American engineer traveling up the Yangtze on a river junk during the 1920s and discovering that his romantic concepts of China bring disaster. His 1965 novel, White Lotus, is exploration of the African American experience prior to civil rights as reflected in an alternate history in which white Americans are enslaved by the Chinese after losing "the Great War" to them.
 Passage 2:From the bioelectricity of nerves, Marxow turned his attention, from 1876 on, to the global electrical activity of the cerebral hemispheres. Neuroanatomists had already determined at the time that its nervous tissue was also composed of cells (the neurons), with their bodies mainly located in the gray matter, and filamentary prolongations, the dendrites and the axons. Thus, it was only natural to assume that they would also display electrical activity. This important discovery, however, had not been made until that time, because many desynchronized electrical potentials with different polarities produce a cumulative global potential which is actually very small and difficult to detect with the sensitivity range of the measuring devices available at the time. Despite this, Marxow was able to prove for the first time that the peripheral stimulation of sensory organs, such as vision and hearing were able to provoke event-related small electrical potential swings on the surface of the cerebral cortex which was related to the projection of those senses. Strangely, however, Marxow did not publish his results, choosing instead to deposit them in a bank safe, with instructions to reveal them in 1883 only. Meanwhile, the first publications about what was later to be called the electroencephalogram came to light, independently demonstrated by Richard Caton (1842–1926), in Great Britain, and Adolf Beck (1863–1942) in Poland, both using laboratory animals.
 Passage 3:Born in Medicine Lodge, Kansas, Duryea grew up in Denton, Texas and graduated from Denton High School. Duryea played college basketball first at Pan American University (now the University of Texas Rio Grande Valley) with the Broncs in the 1984–85 season, then transferred to North Texas State University (now the University of North Texas) and played for the Mean Green from 1986 to 1988. A guard at both schools, Duryea was a team captain as a senior and helped North Texas State win the Southland Conference Men's Basketball Tournament, which qualified the team for the 1988 NCAA Tournament. Duryea graduated from North Texas State in 1988 with a degree in business administration.

Passage 1:Kim Jae-hwan (Hangul: 김재환; born 13 August 1996) is a South Korean badminton player. He graduated from the Jeonju Life Science High School, and now educated at the Wonkwang University. In his junior career, he had collected a gold and two bronzes at the World Junior Championships, and also three silvers and a bronze at the Asian Junior Championships. In 2016, he won the men's doubles title with his partnered Choi Sol-gyu at the World University Championships in Russia.

 Passage 2:Stanford was commissioned into the Welsh Guards in 1987 and saw active service during the Troubles in Northern Ireland for which he was appointed a Member of the Order of the British Empire in October 1993. He went on to become commanding officer of 1st Battalion the Welsh Guards in which capacity he was deployed to Bosnia and Herzegovina on peace keeping duties in 2006. He was the Field Officer in Brigade Waiting and commanded the parade in Trooping the Colour 2007.
