Question: What year was the single that once held the title of best-selling digital song of all time release? Passage:Described by will.i.am as "party album[s]", The Black Eyed Peas released the electronic dance-influenced The E.N.D. and The Beginning in 2009 and 2010, following the 2008 election of Barack Obama as President of the United States. The band welcomed Obama's election; will.i.am had recorded and released "Yes We Can", a single that promoted Obama's election campaign during the Democratic Party primaries, and often claims the song had helped Obama get elected. The band's most commercially successful single during this period, "I Gotta Feeling", was inspired by the band's perception of being "in the center of a ginormous change in America". The track became the best-selling digital song of all time until it was surpassed by Pharrell Williams' "Happy" in 2014. By the end of 2010, The E.N.D. had sold over eleven million copies worldwide, while The Beginning had sold over two million copies worldwide. The band had intended to return to the studio to create their seventh studio album soon after the release of The Beginning, though frequent delays and Taboo's diagnosis with testicular cancer in 2014, along with his subsequent treatment and recovery, led to the project being put on hiatus.

Question: How many games were won in the 2009 CECAFA Cup by the team that Eritrea beat 3-1? Passage:Eritrea returned to the 2009 CECAFA Cup in Nairobi. A young squad was assembled with just 12 days' training. In Group B, they gained a surprise draw with Zimbabwe, lost narrowly to Rwanda, and beat Somalia 31. They were easily beaten 40 in the quarter-finals by Tanzania. Twelve squad members failed to report for the return flight, and sought the assistance of the Refugee Consortium of Kenya. They were believed to be in hiding in Eastleigh, an eastern suburb of Nairobi home to many immigrants. Nicholas Musonye, the secretary-general of CECAFA, feared that the government might react by refusing to let the team travel abroad in future. The twelve players were later granted interim asylum by the United Nations High Commissioner for Refugees in Kenya. Eleven of these players have since travelled to Adelaide in Australia with two of them, Samuel Ghebrehiwet and Ambes Sium, signing for Gold Coast United in the A-League in August 2011.

Question: What country is Zeesen a part of? Passage:The name "Lord Haw-Haw of Zeesen" was coined in 1939 by the pseudonymous Daily Express radio critic Jonah Barrington, but this referred initially to Wolf Mittler (or possibly Norman Baillie-Stewart). When Joyce became the best-known propaganda broadcaster, the nickname was transferred to him. Joyce's broadcasts initially came from studios in Berlin, later transferring (because of heavy Allied bombing) to Luxembourg and finally to Apen near Hamburg, and were relayed over a network of German-controlled radio stations that included Hamburg, Bremen, Luxembourg, Hilversum, Calais, Oslo, and Zeesen. Joyce also broadcast on and wrote scripts for the German Buro Concordia organisation, which ran several black propaganda stations, many of which pretended to broadcast illegally from within Britain. His role in writing the scripts increased over time, and the German radio capitalized on his public persona. Initially an anonymous broadcaster, Joyce eventually revealed his real name to his listeners; and he would occasionally be announced as "William Joyce, otherwise known as Lord Haw-Haw". Urban legends soon circulated about Lord Haw-Haw, alleging that the broadcaster was well-informed about political and military events to the point of near-omniscience.
