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: How many years were there between Jingaku Takashi first jointed the Izutsu stable and Sakahoko joining the same stable? Passage:He came from the same area of Japan as future stable-mates Sakahoko and Terao. He was fond of kendo at school. He joined Izutsu stable in 1977, and first reached a sekitori rank in July 1982 when he was promoted to the juryo division. He first made the top makuuchi division in January 1983 but posted a losing record of 411 and so was immediately demoted. He won promotion back to the top division in January 1984, and remained there for virtually all of the rest of his career. In September 1984 he defeated a yokozuna for the first time when he upset Kitanoumi in one of the latter's final tournaments. He made the sanyaku ranks for the first time in November 1987 when he reached komusubi, but he proved to be out of his depth and scored only two wins against thirteen losses. He made komusubi once more in September 1990 at the age of 30, but again struggled, winning only three bouts. He suffered from stage fright, losing weight during tournaments because of stomach upsets. This affected his performance against top ranked wrestlers he stumbled out of the dohyo in a match against Hokutoumi in September 1990 with his opponent barely having to touch him. He was restricted by a foot problem as well as digestive illness towards the end of his career. After 46 consecutive tournaments in the top division he was demoted to juryo after scoring only 4-11 at maegashira 15 in the July 1991 tourney, and he pulled out of the following tournament with a knee injury after fighting only one match. This brought to an end his streak of 1036 consecutive matches from sumo entry. He announced his retirement shortly afterwards.
