[EX Q]: 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.

[EX Q]: Question: During what years was "Joliet" Jake Blues in prison? Passage:Blues vocalist and petty criminal "Joliet" Jake Blues is paroled on good behavior grounds from Joliet Correctional Center after serving three years of a five-year sentence, and is picked up by his blood brother Elwood in his Bluesmobile, a battered, decommissioned police car. Elwood demonstrates its capabilities by jumping an open drawbridge. The brothers visit the Roman Catholic orphanage where they were raised, and learn from Sister Mary "the Penguin" Stigmata and old friend Curtis that it will be closed unless $5,000 in property taxes is collected. Jake offers to steal the money, but Sister Mary is offended. During a sermon by the Reverend Cleophus James at the Triple Rock Baptist Church, Jake has another idea: they can re-form their band, the Blues Brothers, which disbanded while Jake was in prison, and raise the money to save the orphanage.

[EX Q]: Question: Was Kassel the capital of a country at the time? Passage:After his school-leaving examination (Abitur) at the secondary school Antonianum in Vechta Ludger Gerdes studied at the Academy of Arts in Münster with Timm Ulrichs and Lothar Baumgarten from 1975 to 1977, and from 1977 to 1982 at the Düsseldorf Academy of Arts with Gerhard Richter. At the beginning of the 1980s Gerdes stood out in exhibitions and actions with his criticism of the link between modern art, the museum and the temporary exhibition. At this time he exhibited among others along with Thomas Schütte. He pleaded for works of art as a means for the organization of public space and as a medium of communication. The English landscape garden was a particularly important historical model of this to him. At this time he was regarded as the intellectual head of the artist-group of Düsseldorf pattern makers (Düsseldorfer Modellbauer). In 1982 he was included in the documenta 7 in Kassel. He became known to a larger public in 1987 with his land art project A Ship for Münster (Ein Schiff für Münster) for the show "Skulptur.Projekte" in Münster. From 1990 to 1992 he taught at the Städelschule, Frankfurt; from 1998 to 2004 he was professor for painting and multimedia at the art academy in Karlsruhe; since 2005 he was professor for painting at the Muthesius Art Academy in Kiel. Parallel to his professorship he lived and worked as an artist in Munich and Düsseldorf.
