Example Input: Question: Which of the four expansion teams had the best record in their first year? Passage:In 1969, the Padres joined the ranks of Major League Baseball as one of four new expansion teams, along with the Montreal Expos (now the Washington Nationals), the Kansas City Royals, and the Seattle Pilots (now the Milwaukee Brewers). Their original owner was C. Arnholt Smith, a prominent San Diego businessman and former owner of the PCL Padres whose interests included banking, tuna fishing, hotels, real estate and an airline. Despite initial excitement, the guidance of longtime baseball executives, Eddie Leishman and Buzzie Bavasi as well as a new playing field, the team struggled; the Padres finished in last place in each of its first six seasons in the NL West, losing 100 games or more four times. One of the few bright spots on the team during the early years was first baseman and slugger Nate Colbert, an expansion draftee from the Houston Astros and still the Padres' career leader in home runs.

Example Input: Question: How many years were there between the re-forming of the 20 Battery Royal Artillery and the beginning of the Cuban missile crisis? Passage:After the Second World War the Battery was re-formed in 1955 as 20 Medium Battery as part of 21 Med Regt based at Redford Barracks, Edinburgh but deployed in the Internal Security role to Cyprus in 1956 where the Regt lost several men to the EOKA terrorists. Re-numbered again and re-rolled (a change of equipment and role) as an Amphibious Operations (AO) Battery. They were posted to Hong Kong and renamed 20 Commando (AO) Battery as part of 29 Commando Regiment. Due to the fact that only 20 and 148 Commando (AO) Battery fulfilled the AO roll there was a lot of movement between the batteries most men serving in both. The battery had absorbed 3 (AO) Troop on their move to Hong Kong and was involved in a number of operations including the Korean War and a little known operation in the Caribbean during the Cuban missile crisis. The Battery was involved in clearing Russian, American and Cuban personnel off remote Caribbean islands in the region and arrested 60 men who later turned out to be CIA operatives, causing a minor political incident. The Battery was placed into suspended animation in 1969 following the downsizing of the British Army and the reduction to one Commando Artillery Regiment, having lost out to 148 Commando (AO) Battery. Many of 20 Commando (AO) Battery's personnel ended up in 148 Battery and so did much of the battery property.

Example Input: Question: Was the opening game against FC Groningen where Jozefzoon was an unused substitute a home game for Ajax? Passage:A Winger and attacking midfielder, Jozefzoon began his career with spells at CTO '70 and AFC. He joined the Ajax Youth Academy in 2006 and signed a three-year professional contract in June 2008. Jozefzoon won his maiden call into the first team squad for the opening match of the 2010–11 Eredivisie season versus FC Groningen and remained an unused substitute during the 2–2 draw. He made his senior debut six days later, replacing Urby Emanuelson at half time during a 4–2 win over SBV Vitesse. He scored his only goal for the club in a 5–0 KNVB Becker third round win over MVV Maastricht on 22 September 2010. After five appearances during the 2010–11 season, Jozefzoon signed a one-year contract extension in June 2011, but spent the 2011–12 season away on loan and was released at the end of the season.
