Problem: Viking invasions began in the 9th century, followed by more permanent settlements, particularly along the east coast of Ireland, the west coast of modern-day Scotland and the Isle of Man. Though the Vikings were eventually neutralised in Ireland, their influence remained in the cities of Dublin, Cork, Limerick, Waterford and Wexford. England however was slowly conquered around the turn of the first millennium AD, and eventually became a feudal possession of Denmark. The relations between the descendants of Vikings in England and counterparts in Normandy, in northern France, lay at the heart of a series of events that led to the Norman conquest of England in 1066. The remnants of the Duchy of Normandy, which conquered England, remain associated to the English Crown as the Channel Islands to this day. A century later the marriage of the future Henry II of England to Eleanor of Aquitaine created the Angevin Empire, partially under the French Crown. At the invitation of a provincial king and under the authority of Pope Adrian IV (the only Englishman to be elected pope), the Angevins invaded Ireland in 1169. Though initially intended to be kept as an independent kingdom, the failure of the Irish High King to ensure the terms of the Treaty of Windsor led Henry II, as King of England, to rule as effective monarch under the title of Lord of Ireland. This title was granted to his younger son but when Henry's heir unexpectedly died the title of King of England and Lord of Ireland became entwined in one person.

Context and question: The history of the Ottoman Empire during World War I began with the Ottoman engagement in the Middle Eastern theatre. There were several important Ottoman victories in the early years of the war, such as the Battle of Gallipoli and the Siege of Kut. The Arab Revolt which began in 1916 turned the tide against the Ottomans on the Middle Eastern front, where they initially seemed to have the upper hand during the first two years of the war. The Armistice of Mudros was signed on 30 October 1918, and set the partition of the Ottoman Empire under the terms of the Treaty of Sevres. This treaty, as designed in the conference of London, allowed the Sultan to retain his position and title. The occupation of Constantinople and Izmir led to the establishment of a Turkish national movement, which won the Turkish War of Independence (191922) under the leadership of Mustafa Kemal (later given the surname "Ataturk"). The sultanate was abolished on 1 November 1922, and the last sultan, Mehmed VI (reigned 191822), left the country on 17 November 1922. The caliphate was abolished on 3 March 1924.
When did the Turkish War of Independence take place?
Answer: 191922

Question: The Austrian engineer Paul Eisler invented the printed circuit as part of a radio set while working in England around 1936. Around 1943 the USA began to use the technology on a large scale to make proximity fuses for use in World War II. After the war, in 1948, the USA released the invention for commercial use. Printed circuits did not become commonplace in consumer electronics until the mid-1950s, after the Auto-Sembly process was developed by the United States Army. At around the same time in Britain work along similar lines was carried out by Geoffrey Dummer, then at the RRDE.
Is there an answer to this question: England began using the technology on a large scale in what year?

Answer: unanswerable
