Example Input: Question: How old were Norman Tindale and Joseph Birdsell when they published their paper about the 12 Negrito tribes? Passage:In a publication of 1941, Norman Tindale, together with the American anthropologist Joseph Birdsell, published a paper suggesting that there were 12 Negrito tribes living on the coastal and rainforest areas around Cairns. The idea had been developed by Birdsell during field work in 1937-8. They were characterized by very short stature, curly hair, and yellowy-brown skin. Six of them were Dyirbal speakers, such as the Jirrbal, Girramay, Gulngai and Djiru within the Murray Upper/Tully Area. Of the others, located further north beyond Cairns, two spoke varieties of Djabugay, and three spoke dialects of Yidin. The remaining tribe were the Mbabaram, whom Tindale took to be strong evidence for his hypothesis because their language, in so far as it had been reported, diverged substantially from the surrounding tongues, and appeared to be wholly atypical, compared to the standard Australian aboriginal languages.

Example Input: Question: What team had the worst 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: Who owned the Indiana Pacers during the 32nd annual draft? Passage:The 1978 NBA draft was the 32nd annual draft of the National Basketball Association (NBA). The draft was held on June 9, 1978, before the 1978–79 season. In this draft, 22 NBA teams took turns selecting amateur U.S. college basketball players and other eligible players, including international players. The first two picks in the draft belonged to the teams that finished last in each conference, with the order determined by a coin flip. The Indiana Pacers won the coin flip and were awarded the first overall pick, while the Kansas City Kings, who obtained the New Jersey Nets' first-round pick in a trade, were awarded the second pick. The Pacers then traded the first pick to the Portland Trail Blazers before the draft. The remaining first-round picks and the subsequent rounds were assigned to teams in reverse order of their win–loss record in the previous season. A player who had finished his four-year college eligibility was eligible for selection. If a player left college early, he would not be eligible for selection until his college class graduated. Before the draft, five college underclassmen were declared eligible for selection under the "hardship" rule. These players had applied and gave evidence of financial hardship to the league, which granted them the right to start earning their living by starting their professional careers earlier. Prior to the start of the season, the Buffalo Braves relocated to San Diego and became the San Diego Clippers. The draft consisted of 10 rounds comprising the selection of 202 players.
