question:
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.

question:
Question: What position did Dhawal Kulkarni play on the squad? Passage:The Indian Squads were announced on 13 February. Dhawal Kulkarni got his maiden call up to the national squad, having been selected for the test squad after a strong debut Ranji trophy season where he was the highest wicket taker. L Balaji made a return to the Test squad after a five-year hiatus having last played in a test in 2004. Balaji was dropped from the ODI squad after he played in a single match in the previous tour, he was replaced by the now fit Munaf Patel. In the test squad Balaji replaced Pragyan Ojha with the selectors opting for an extra seamer instead of an extra spinner for the tour. Ojha retained his place in the ODI and T20 squads. Subramaniam Badrinath was dropped from the test squad in favour of reserve Wicket-Keeper Dinesh Karthik after Karthik too had a strong Ranji trophy season. Karthik was selected for all three squads, replacing Jadeja in the ODI squad. Ravindra Jadeja's impressive ODI debut was rewarded with a call up to the Twenty20 squad but Jadeja will be replaced by Sachin Tendulkar for the subsequent ODI series. Munaf Patel made a return to all three squads after having to pull out midway through the previous tour of Sri Lanka due to injury. Harbhajan Singh also made a return to all three squads after having to pull out at the beginning of the previous tour to Sri Lanka due to injury.

question:
Question: What year did Montana's successor take over? Passage:Walsh first developed what would become the West Coast offense when he was offensive coordinator of the Cincinnati Bengals, working under legendary head coach Paul Brown. However, Walsh truly perfected this strategy as the head coach of the San Francisco 49ers. His teams were led by quarterback Joe Montana. Montana, who was noted for his ability to remain calm under pressure, also possessed good mobility and an accurate passing arm. Another important player in the 49ers offense was Roger Craig, a swift, speedy running back who could also catch passes out of the backfield and was a good receiver. Walsh's 49ers teams also featured several All-Pro wide receivers, including Dwight Clark, John Taylor, and Jerry Rice. The 49ers were one of the NFL's powerhouses in the 1980s and 1990s, under the guidance of head coaches Bill Walsh (1979–1988) and George Seifert (1989–1996). Walsh won three Super Bowls in the 1981, 1984 and 1988 seasons. Seifert won two Super Bowls in 1989 and 1994. Montana, Walsh and Rice are in the Pro Football Hall of Fame, and so is Montana's successor, quarterback Steve Young. Like Montana, Young was a great running quarterback and a very efficient passer.
