Question: Did the war that Hurst served in last longer than 2 years? Passage:Aurthur Frederick Hertz was born in Bradford to Fanny Mary and William Martin Hertz, a merchant of German Jewish descent. Hertz changed the spelling of his surname to Hurst in 1916. He attended Bradford Grammar School and Manchester Grammar School before graduating from Magdalene College, Oxford in 1904. He joined the staff of Guy's Hospital in 1906 and ran his own private practice before serving in World War I as a consulting physician stationed in Salonika. From 1916 to 1918, Hurst led the neurology department at Netley Hospital. Seale-Hayne College was repurposed as a military hospital that same year. Hurst moved there to help with treatment of shell shock, working at Netley until 1919. After the war, Hurst relocated his private practice to Windsor and retired in 1939. Upon his retirement, Hurst became a consulting physician and served on Guy's Hospital board of governors. Hurst was knighted in 1937 six years after his older brother Gerald Berkeley Hurst. He died in Birmingham in 1944, aged 65.

Question: What was the result of the case that United Kingdom brought against Albania before the International Court of Justice? Passage:The Corfu Channel Incident refers to three separate incidents involving Royal Navy ships in the Straits of Corfu which took place in 1946, and it is considered an early episode of the Cold War. During the first incident, Royal Navy ships came under fire from Albanian fortifications. The second incident involved Royal Navy ships striking mines and the third incident occurred when the Royal Navy conducted mine-clearing operations in the Corfu Channel, but in Albanian territorial waters, and Albania complained about them to the United Nations. This series of incidents led to the Corfu Channel Case, where the United Kingdom brought a case against the People's Republic of Albania to the International Court of Justice. Because of the incidents, Britain, in 1946, broke off talks with Albania aimed at establishing diplomatic relations between the two countries. Diplomatic relations were only restored in 1991.
