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: Which school Hodes started teaching at after WWII has a higher enrollment? Passage:Hodes worked as an intern and resident at the Children's Hospital of Philadelphia until 1935, when he moved to Baltimore to take up a position at the Harriet Lane Home of Johns Hopkins Hospital as the dispensary director. In 1936, he developed a method that used ultraviolet light to reduce the infectiousness of viruses, a technique that later was used to create commercial vaccines against rabies and influenza. He became a pediatrician at Johns Hopkins in 1938 while also serving as the medical director of Sydenham Hospital for Communicable Diseases. During an outbreak of diarrhea in 1942, he isolated the first virus known to cause diarrhea, later identified as rotavirus. The same year, he became the first to isolate the measles virus from the brain of a child who had died from measles encephalitis. While stationed in Guam with the U.S. Navy in World War II, he discovered that the Japanese encephalitis virus was spread by mosquitoes. Hodes continued working in Baltimore after World War II, and started teaching at the Johns Hopkins School of Medicine and School of Hygiene, as well as the University of Maryland School of Medicine.
