The end of the unification process is officially referred to as German unity, celebrated on 3 October (German Unity Day). Following German reunification, Berlin was once again designated as the capital of united Germany., Subject: umbau-wagen, Relation: operator, Options: (A) deutsche bahn (B) deutsche bundesbahn (C) germany

Input: Consider Input: Context: Hut 8 was a section in the Government Code and Cypher School (GC&CS) at Bletchley Park (the British World War II codebreaking station) tasked with solving German naval (Kriegsmarine) Enigma messages. The section was led initially by Alan Turing. He was succeeded in November 1942 by his deputy, Hugh Alexander. Patrick Mahon succeeded Alexander in September 1944., The Axis powers ("Sjikukoku"), also known as the RomeBerlinTokyo Axis, were the nations that fought in World War II against the Allied Powers. The Axis agreed on their opposition to the Allies, but did not completely coordinate their activity., Buckinghamshire (or ), abbreviated Bucks, is a county in South East England which borders Greater London to the south east, Berkshire to the south, Oxfordshire to the west, Northamptonshire to the north, Bedfordshire to the north east and Hertfordshire to the east., The Lorenz SZ40, SZ42, SZ42A and SZ42B were German rotor stream cipher machines used by the German Army during World War II. They were developed by C. Lorenz AG in Berlin. The model name "SZ" was derived from "Schlussel-Zusatz", meaning "cipher attachment". The instruments implemented a Vernam stream cipher., Hut 6 was a wartime section of the Government Code and Cypher School (GC&CS) at Bletchley Park, Buckinghamshire, Britain, tasked with the solution of German Army and Air Force Enigma machine cyphers. Hut 8, by contrast, attacked Naval Enigma. Hut 6 was established at the initiative of Gordon Welchman, and was run initially by Welchman and fellow Cambridge mathematician John Jeffreys., The Enigma machines were a series of electro-mechanical rotor cipher machines developed and used in the early- to mid-twentieth century to protect commercial, diplomatic and military communication. Enigma was invented by the German engineer Arthur Scherbius at the end of World War I. Early models were used commercially from the early 1920s, and adopted by military and government services of several countries, most notably Nazi Germany before and during World War II. Several different Enigma models were produced, but the German military models are the most commonly recognised. However, Japanese and Italian models were also in use., Ultra was the designation adopted by British military intelligence in June 1941 for wartime signals intelligence obtained by breaking high-level encrypted enemy radio and teleprinter communications at the Government Code and Cypher School (GC&CS) at Bletchley Park. "Ultra" eventually became the standard designation among the western Allies for all such intelligence. The name arose because the intelligence thus obtained was considered more important than that designated by the highest British security classification then used ("Most Secret") and so was regarded as being "Ultra secret". Several other cryptonyms had been used for such intelligence. British intelligence first designated it "Boniface"presumably to imply that it was the result of human intelligence. The U.S. used the codename "Magic" for its decrypts from Japanese sources., William Gordon Welchman (15 June 1906, Bristol, England 8 October 1985, Newburyport, Massachusetts, US) was a British mathematician, university professor, Second World War codebreaker at Bletchley Park and author. After the war he moved to the US, and later took American citizenship., Bletchley Park was the central site for British codebreakers during World War II. Run by the Government Code and Cypher School (GC&CS), it regularly penetrated the secret communications of the Axis Powersmost importantly the German Enigma and Lorenz ciphers. The official historian of World War II British Intelligence has written that the "Ultra" intelligence produced at Bletchley shortened the war by two to four years, and that without it the outcome of the war would have been uncertain., World WarII (often abbreviated to WWII or WW2), also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the world's nationsincluding all of the great powerseventually forming two opposing military alliances: the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. In a state of "total war", the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, erasing the distinction between civilian and military resources. Marked by mass deaths of civilians, including the Holocaust (in which approximately 11 million people were killed) and the strategic bombing of industrial and population centres (in which approximately one million were killed, and which included the atomic bombings of Hiroshima and Nagasaki), it resulted in an estimated 50 million to 85 million fatalities. These made World WarII the deadliest conflict in human history., Bletchley is a constituent town of Milton Keynes, in the ceremonial county of Buckinghamshire, England. It is situated in the south-west of Milton Keynes, and is split between the civil parishes of Bletchley and Fenny Stratford and West Bletchley., For other persons named David / Dai Rees , see David / Dai Rees David Rees ScD Cantab , FIMA , FRS ( 29 May 1918 -- 16 August 2013 ) was an emeritus professor of pure mathematics at the University of Exeter , having been head of the Mathematics / Mathematical Sciences Department at Exeter for many years .
