Example Input: Question: Which Super Kings player who were ahead of Badree in team depth is the oldest? Passage:Badree first played for an overseas Twenty20 franchise in January 2013, when he played for the Khulna Royal Bengals in the 2013 Bangladesh Premier League (BPL) season. Later in the year, he signed with the Rajasthan Royals for the 2013 Indian Premier League (IPL), although he played only a single game (against the Delhi Daredevils). In the 2014 IPL auction, Badree was bought by the Chennai Super Kings for US$50,000. He went on to play four matches for the team during the 2014 season, but took only two wickets, with Ravichandran Ashwin and Ravi Jadeja being the preferred spin options. Later in 2014, Badree signed with the Brisbane Heat for the 2014–15 Big Bash League season in Australia. He was unable to play any matches due to a shoulder injury, but re-signed for the 2015–16 season. He struggled for form early in the season, going wicketless in his first three games, but eventually bounced back to finish as his team's leading wicket-taker, with nine wickets from eight matches. This included 5/22 in the final game of the season, against the Melbourne Stars.

Example Input: Question: How long had Central States Wrestling been in business the year Robertson won the NWA Central States Television Championship? Passage:Robertson moved to Central States Wrestling, where he won the majority of his titles. On October 22, 1981, he won the NWA Central States Television Championship with a victory over Gene Lewis. He lost the belt to Oliver Humperdink later that year but soon regained it in a rematch. On February 18, 1982, however, he dropped the belt back to Lewis. This allowed Robertson to focus on the NWA Central States Tag Team Championship, which he won a total of five times. His first reign came in October 1981 when he teamed with Rufus R. Jones to defeat Buzz Tyler and James J. Dillon. His next reign came in March 1982 when he teamed with Steve Regal to win the belts from Roger Kirby and Jerry Valiant. The title changed hands twice more that month, as Kirby and Valiant quickly regained the title only to drop it back to Robertson and Regal. Two months later, Kirby and Valiant won the belts back again. Robertson found a new partner, however, and won the championship by teaming with Hercules Hernandez in August. The reign lasted less than a month, but Robertson and Hernandez held the belts one final time after another victory in September 1982. The following year, Robertson's main success came as a singles wrestler. On February 10, 1983, he won the NWA Central States Heavyweight Championship with a victory over Manny Fernandez. He lost the belt to Bob Brown two months later but regained it in a rematch the following week. Robertson's final title reign ended when he dropped the title to Race on June 2, 1983.

Example Input: Question: Of the cities where Stanislaw Aronson's family moved, which currently has the highest population? Passage:Aronson's mother family came from Łódź. After the German invasion of Poland in 1939, they first moved from Łódź to Warsaw. After a few days, they decided to move further east to the Kresy, where near Równo their relatives owned some land. However, in the meantime the Soviet Union also invaded Poland as part of the Molotov-Ribbentrop Treaty between the Soviet Union and Nazi Germany, and the relatives were arrested by the NKVD and deported eastwards, deep within the Soviet Union. As a result, the family tried to unsuccessfully enter Lithuania, and then into Romania. Eventually they wound up in Soviet-occupied Lwow. According to Aronson, in Lwow, the Soviets pressured Poles, Ukrainians and Jews to sign up for the Komsomol but he personally refused.
