Passage:In 1977, Gregorio returned to Broadway after an eight-year hiatus in the original production of Michael Cristofer's The Shadow Box as Agnes; she garnered nominations for the Tony Award for Best Performance by a Featured Actress in a Play and the Drama Desk Award for Outstanding Featured Actress in a Play.

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 3–1. They were easily beaten 4–0 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 year was the song Shaft performed at the Academy Awards? Passage:The episode was written by Nell Scovell and directed by Wes Archer. In the episode, Bart and Lisa sneak into the sushi bar's karaoke room and sing the theme song to the 1971 film Shaft, "Theme from Shaft". The Fox network censors originally did not want the staff to use the song because they thought the lyrics were too obscene for television. In order to prove the censors wrong and show that it could appear on television, the staff dug up footage from an old Academy Awards ceremony at which the song was performed by Isaac Hayes. When the chef at the sushi bar finds out Homer has been poisoned, he yells at his apprentices in Japanese. The staff wanted the language they spoke to be actual Japanese, so they hired a Japanese actor who translated the lines for them. The episode introduced the character Akira, who has appeared many times later on the show. American actor George Takei provided the voice of Akira, although the character was voiced in later episodes by Hank Azaria. The episode featured many other guest appearances; Larry King as himself; Sab Shimono as the sushi bar chef; Joey Miyashima as Toshiro, the apprentice chef who slices up the fugu; and Diane Tanaka as hostess of the bar. King's role was first offered to American singer Bruce Springsteen, but he turned it down. According to showrunner Sam Simon, actor William Shatner also rejected the part.
