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: What age was Hans Asperger when he invented the term Autistic psychopathy? Passage:Michael Fitzgerald, a professor of child and adolescent psychiatry, published a cornucopia of pathographies of outstanding historical personalities, mostly stating that they had Asperger syndrome, which is on the autism spectrum. In his 2004 published anthology Autism and creativity, he classified Hitler as an "autistic psychopath". Autistic psychopathy is a term that the Austrian physician Hans Asperger had coined in 1944 in order to label the clinical picture that was later named after him: Asperger syndrome, which has nothing to do with psychopathy in the sense of an antisocial personality disorder. Fitzgerald appraised many of Hitler's publicly known traits as autistic, particularly his various obsessions, his lifeless gaze, his social awkwardness, his lack of personal friendships, and his tendency toward monologue-like speeches, which, according to Fitzgerald, resulted from an inability to have real conversations.
