Example Input: Question: How many nations comprise the organization that Albania complained to concerning Royal Navy conducting mine-clearing operations in Albanian territorial waters, 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.

Example Input: Question: How many soldiers did Britain send to World War I the year Roebuck arrived on the Western Front? Passage:As a boy, Roebuck worked as a trammer and after being sentenced to one month's imprisonment for stealing a watch in 1904, he enlisted in the York and Lancaster Regiment. Over the next seven years, he was stationed in India and Ireland and was promoted to lance corporal, but was demoted back to private in 1910 for "misconduct". He married in 1908 and had two children. Roebuck was discharged into the reserves in 1912 and likely returned to work as a miner prior to becoming a professional footballer in 1913. After Britain's entry into the First World War in August 1914, he was called up by the York and Lancaster Regiment and arrived on the Western Front in September 1914. On 18 October 1914, Roebuck recorded as "presumed dead" after an attack near Beaucamps-Ligny during the Race to the Sea. His death was confirmed by two comrades in January 1915. Roebuck is commemorated on the Ploegsteert Memorial to the Missing.
