Example Input: Question: What team had the best record in the Latvian Higher League the year that Karlsons was the top scorer with 26 goals? Passage:As a youth player Karlsons played for his local club FK Liepājas Metalurgs, being taken to the first team in 1998, at the age of 17. He spent the next six seasons with the club, becoming the second top scorer of the Latvian Higher League in 2003 with 26 goals, completing two hat-tricks during the season. All in all he played 96 matches for his local club, scoring 40 goals. After these bright appearances he had impressed clubs abroad, and in January 2004 Karlsons went on a month-long trial with the Russian Premier League club Shinnik Yaroslavl. Afterwards he signed a three-year contract with them. However, his spell there wasn't as successful as expected and was very short. After just one season, during which he played only 8 league matches without scoring goals, Karlsons returned to the Latvian Higher League, signing with the newly promoted, ambitious club Venta Kuldiga in 2005. However, the club struggled financially and after just five matches had to let some of their players go, including Karlsons, who returned to his hometown club, Liepājas Metalurgs later that year. He spent the next three seasons there, once again showing great performance. He scored a hat-trick in the 2005 season, and he also scored in the Latvian Cup final on 25 September 2005, which Metalurgs lost 2–1 to Venta Kuldīga. Another hat-trick came in the 2006 season, which Karlsons finished as the second top scorer with 14 goals under his belt. In the Latvian Cup he scored a hat-trick in the 6–1 semi-final victory over Dižvanagi Rēzekne and then scored in the final, which the club won 2–1 over Skonto Riga. In December 2006 Karlsons was named the runner-up of the Latvian Player of the Year Award by the Latvian Football Federation behind the winner Aleksandrs Koļinko, who that time was the first-choice keeper for Rubin Kazan in the Russian Premier League. His contract with Metalurgs expired in July 2007 and it was not renewed. Player was then linked with the English Championship club Bristol City, before going on trial with Southampton. In January 2008 he had a two-day trial with Wolverhampton Wanderers. Karlsons then had trials in the Netherlands with Zwolle and De Graafschap,

Example Input: Question: What was the first article that Khariton Chebotaryov wrote for the Moskovskie Vedomosti? Passage:Khariton Chebotaryov was born in Vologda into a poor family. In 1755, he entered a gymnasium under the Moscow University, becoming a university student six years later. Upon his graduation from the university in 1764, Chebotaryov was soon hired by his alma mater as a translator from Latin and German. In 1767, he was transferred to the gymnasium as a teacher of history and geography. In 1773, Khariton Chebotaryov was entrusted with teaching Russian literature, simultaneously doing translations from Latin, German, and French with his students. In 1775, he was appointed deputy librarian (суб-библиотекарь) of the university library (only a professor could hold this post) and editor-in-chief of the Moskovskie Vedomosti for the next three years. In 1776, Khariton Chebotaryov became an extraordinary professor at the Russian Literature Department, simultaneously remaining a philosophy and world history teacher at the gymnasium. Upon the death of Professor Johann Gottfried Reichel, Chebotaryov delivered lectures on European history and Russian literature at the gymnasium. In 1778, Khariton Chebotaryov was made an ordinary professor and appointed librarian and censor at the university theater. In 1778-1783, he was a secretary of the academic council (университетская конференция), inspector of the university gymnasium and normal school. In 1782, Khariton Chebotaryov was promoted to the rank of a collegiate assessor and then court councilor (1786). At the behest of the Empress, he and Anton Barsov were engaged in copying out notes from Russian chronicles, located at synodal and patriarchal libraries and Moscow State Archive. These notes were later presented to Catherine the Great and then served as a source for her Notes on Russian History. In consideration of his efforts, Khariton Chebotaryov was rewarded with 500 silver rubles. After the transformation of the university charter, Chebotaryov was elected its rector (being in the rank of collegiate councilor) and awarded with the Order of Saint Anna (2nd Class). Upon his resignation from this post, Chebotaryov was appointed a permanent representative of the university board, remaining as such until his death. In 1809, Khariton Chebotaryov was promoted to the rank of state councilor. During the Patriotic War of 1812, he lost his precious library and personal archives, which would come to him as a shock and greatly undermine his health. As a result, Chebotaryov suffered a stroke and died on July 26, 1815. He was interred at the Vagankovo Cemetery in Moscow.
