Question: How old is the lead singer of Block Party? Passage 1:Declan O'Keeffe (born 1972 in Rathmore, County Kerry) is a former Irish sportsperson. He played Gaelic football at various times with his local clubs Rathmore in Kerry and Clooney/Quin and St Josephs Doora-Barefield in Clare. He was a member of the Kerry senior inter-county team from 1996 until 2003. He won All-Ireland Senior Football Championships in 1997 & 2000. He also won an All-Ireland Junior Football Championship in 1994. He won Munster Under-21 Football Championship medals in 1992 and 1993, and a Munster Minor Football Championship medal in 1990. He won an International Rules in 1999 and a Railway Cup. He won 3 County Championships with East Kerry in 1997, 1998 and 1999.
Passage 2:The coalition total was reduced to 64 seats when Rob Oakeshott, former state Nationals turned independent MP, won the seat of Lyne at the September 2008 Lyne by-election, resulting from the resignation of former Howard minister and Nationals leader Mark Vaile. The April 2008 Gippsland by-election, resulting from the resignation of the former Howard minister and Nationals MP Peter McGauran, saw the Nationals' Darren Chester retain the seat, receiving a swing of 6%. The Liberals suffered a swing in the September 2008 Mayo by-election resulting from the resignation of former Howard minister and Liberal leader Alexander Downer, and came close to losing the seat to the Greens candidate. The Liberals retained seats at the Bradfield and Higgins by-elections in December 2009. The member for Ryan, Michael Johnson, was expelled from the Liberal National Party on 20 May 2010, reducing the Coalition to 63 seats.
Passage 3:Multiple artists have cited the band as an influence. Kele Okereke, lead singer of London band Bloc Party, said that he started making music because of Suede's Dog Man Star, and called it "the first record [he] fell in love with". Kate Jackson, lead singer of English indie rock band The Long Blondes has said in interviews of her love for Suede. In 2007, she admitted that Suede got her into music, saying: "Suede's debut album was unlike anything I'd heard before. It was the opposite of grunge, which I hated, and my escape from Bury St Edmunds." Christopher Owens of the Californian indie pop group Girls named Suede as one of his major influences, and his vocal style has been compared to that of Anderson. My Chemical Romance frontman Gerard Way cited Suede as a prominent inspiration for his 2014 solo album, Hesitant Alien. The band have also served as an influence on acts such as Sons and Daughters, Dum Dum Girls, and Drowners, who took their name from the similarly titled Suede song. Canadian rock band Destroyer named their 2017 album ken after the original title for "The Wild Ones".

Question: How many games were won in the 2009 CECAFA Cup by the team that Eritrea beat 3-1? Passage 1: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.
Passage 2:Breaking away from the confines of the group, Gaines became part of the 1955 R&B Caravan of Stars, with Bo Diddley, Big Joe Turner, and Etta James. Their tour culminated with an appearance at New York's Carnegie Hall. Without any tangible success, Gaines recorded for the Champion and Poncello labels for another few years, as well as joining Bill Doggett's band as lead vocalist. In 1963, he joined Bill "Hoss" Allen's repertoire of artists, and by 1966 had issued the album The Best of Luck to You, seeing the title track reach the Top 40 in the US R&B chart. He appeared on the television program The !!!! Beat, and later released material for King and Sound Stage 7, including his cover version of "Hymn Number 5". Recordings made between 1967 and 1973 for De Luxe were reissued in 1998. On many of his De Luxe recordings in the late 1960s and early 1970s, Gaines was backed by Freddy Robinson's orchestra.
Passage 3:Chappell grew up in the beachside suburb of Glenelg and attended the local St Leonard's Primary School where he played his first competitive match at the age of seven. He was later selected for the South Australian state schoolboys team. He then enrolled at Prince Alfred College, a private secondary school noted for producing many Test cricketers, including the Australian captains Joe Darling and Clem Hill. His other sporting pursuits included Australian football and baseball: Chappell's performances for South Australia in the Claxton Shield won him All-Australian selection in 1964 and 1966 as a catcher. He credits Vic Richardson, who had represented both SA and Australia in baseball during the 1920s, for his love of the sport. At the age of 18, his form in grade cricket for Glenelg led to his first-class debut for South Australia (SA) against Tasmania in early 1962.

Question: Which Open winner has won the most tournaments overall, the player from Germany or the player from Great Britain? Passage 1:Before this year, the tournament was won by a home favorite on several occasions: Guy Forget in 1996, Fabrice Santoro in 1999, Arnaud Clement in 2006, and Gilles Simon in 2007. The record for most titles is three, won by the Swiss player Marc Rosset in its first two years in 1993 and 1994, as well as in 2000; the Swedish player Thomas Enqvist also won three, in 1997, 1998, and 2002. It is also one of the few ATP tournaments to have been won only by European players, with France with five (Forget, Santoro, Clement, Simon, and this year's winner Jo-Wilfried Tsonga), Sweden with 4 (Enqvist, Joachim Johansson), Switzerland with four (Rosset, Roger Federer), Germany with one (Boris Becker), Russia with one (Yevgeny Kafelnikov), Slovakia with one (Dominik Hrbaty), and Great Britain with one (Andy Murray).
Passage 2:Natural strontium is a mixture of four stable isotopes: Sr, Sr, Sr, and Sr. Their abundance increases with increasing mass number and the heaviest, Sr, makes up about 82.6% of all natural strontium, though the abundance varies due to the production of radiogenic Sr as the daughter of long-lived beta-decaying Rb. Of the unstable isotopes, the primary decay mode of the isotopes lighter than Sr is electron capture or positron emission to isotopes of rubidium, and that of the isotopes heavier than Sr is electron emission to isotopes of yttrium. Of special note are Sr and Sr. The former has a half-life of 50.6days and is used to treat bone cancer due to strontium's chemical similarity and hence ability to replace calcium. While Sr (half-life 28.90years) has been used similarly, it is also an isotope of concern in fallout from nuclear weapons and nuclear accidents due to its production as a fission product. Its presence in bones can cause bone cancer, cancer of nearby tissues, and leukemia. The 1986 Chernobyl nuclear accident contaminated about 30,000km with greater than 10 kBq/m with Sr, which accounts for 5% of the core inventory of Sr.
Passage 3:On a smuggling run from Colombia, having dumped packages of cocaine off near Blairsville, Georgia, Thornton jumped from his auto-piloted Cessna 404. In the September 11, 1985, jump, he was caught in his parachute and ended up in a free fall to the ground. His dead body was found in the back yard of Knoxville, Tennessee, resident Fred Myers. The plane crashed over away in Hayesville, North Carolina. At the time of his death Thornton was wearing night vision goggles, a bulletproof vest, Gucci loafers, and a green army duffel bag containing approximately 40 kilos (88lbs.) of cocaine valued at $15 million, $4,500 in cash, six . gold Krugerrands, knives, and two pistols. Three months later, a dead black bear was found in the Chattahoochee National Forest that had apparently overdosed on cocaine dropped by Thornton.
