Q: Question: How old was Walter's oldest son when Walters passed away? Passage:Walter was born in Kansas City, Missouri, United States, in 1910. His ancestry was German/British on his father's side, and American/British on his mother's side. He was brought to England in 1915, and educated at Westminster School and afterwards in King's College, Cambridge, in 1931. He failed to obtain a research fellowship in Cambridge and so turned to doing basic and applied neurophysiological research in hospitals, in London, from 1935 to 1939 and then at the Burden Neurological Institute in Bristol, from 1939 to 1970. He also carried out research work in the United States, in the Soviet Union and in various other places in Europe. He married twice, had two sons from his first marriage, and one from the second. According to his eldest son, Nicolas Walter, "he was politically on the left, a communist fellow-traveller before the Second World War and an anarchist sympathiser after it." Throughout his life he was a pioneer in the field of cybernetics. In 1970, he suffered a brain injury in a motor scooter accident. He never fully recovered and died seven years later, on May 6, 1977.

Q: Question: When was Taylor's place of birth founded? Passage:Taylor was born in 1861 in Peckham, to John and Mary Jane Cash. He worked in stockbroker's office in London and in 1880s he emigrated to South Africa and than to Western Australia in early 1890 following the Ashburton rush.

Sitting at the town council, he was elected on 3 August 1896 one of the three members of the Western Australian Legislative Council for the East Province. He was one of the ten Western Australia representatives at the 1897-1898 Australasian Federal Convention, which prepared the federation.

Q: Question: Which of the two rivers the Panzer Corps crossed was larger? Passage:In planning for the actual attack, Manteuffel had divided his 5th Panzer Army into three corps composed of infantry, tanks, and supporting artillery. The main effort, or schwerpunkt, would consist of XLVII Panzer Corps and LVIII Panzer Corps advancing west across the River Our at Ouren from the south or left flank of the German army front. They would then occupy the transportation center of Bastogne, before crossing the Meuse River at Namur. The third group, LXVI Corps, would advance west on either side of the Schnee Eifel. This northernmost, or right wing, element would flank and begin an envelopment of the American forces occupying fortifications on the Schnee Eifel and then converge on the town of Winterspelt. From there, LXVI Corps would cross the Our river and occupy St. Vith on the first day of the attack. LXVI Corps was the weakest of the three corps, with no attached tank division or motor transport, but did include an attached assault gun battalion. The Panzer Lehr Division (Armor Demonstration Division) and the Führer Begleit Brigade (Führer Escort Brigade) were to be held in reserve, with the Führer Begleit only usable with Model's express permission. Manteuffel's preference for the "little slam", or limited solution, was reflected in the absence of planning beyond reaching the Meuse River.
