Question: How long had the Australia women's national wheelchair basketball team existed when Tesch tried out for them? Passage:Tesch started playing wheelchair basketball after one of her physiotherapists noticed how skilled she was at shooting with a foam basketball and perspex backboard during her rehabilitation. Shortly after entering the New South Wales state team, she was invited to try out for and made the Australia women's national wheelchair basketball team in 1990, making her national debut at that year's World Championships and her Paralympic debut at the 1992 Barcelona Games. She was named to the All Star Five at the 1994 Gold Cup, where the Australian team won a bronze medal. She was part of the Australian team at the 1996 Atlanta Paralympics, and was named Most Valuable Player at the 1998 Gold Cup. She was the vice-captain of her country's team at the 2000 Sydney Paralympics, where she won a silver medal. During celebrations after the games, some players from Europe invited her to play in professional men's teams there. She accepted this suggestion, and played in Madrid, Sardinia, and Paris for the next five years, thus becoming the first woman in the world to play wheelchair basketball professionally. She helped establish a women's wheelchair basketball league on the continent and competed in women's teams in Italy and France. She also competed in the silver-medal-winning Australian team at the 2004 Athens Paralympics. She returned home to captain the national squad at the 2008 Beijing Paralympics. In 2010, Tesch competed with her team in the Osaka Cup, a competition for the top five women's international wheelchair basketball teams in the world; her team defeated the number one ranked American team 5537. She was a 4 point player. She retired from the national wheelchair basketball squad in 2011 to concentrate on sailing.

Question: How many albums total did the Beatles record in Hamburg? Passage:Ain't She Sweet was an American album featuring four tracks recorded in Hamburg in 1961 by The Beatles featuring Tony Sheridan (except for the title song with vocal by John Lennon) and cover versions of Beatles and British Invasion-era songs recorded by the Swallows. As Atlantic Records only had rights to four Sheridan/Beatle recordings recorded by Polydor Records, they filled the rest of the album with Beatle and British Invasion cover songs. When this material was released by Atco Records, there were mono (catalogue number 33-169) and stereo (SD 33-169) editions. Atco also added additional drum overdubs to the four Sheridan cuts on top of the original drum tracks. American drummer Bernard Purdie claims to have performed overdubs of unspecified Beatles records, which would most likely have been for Ain't She Sweet, but this has never been officially confirmed.
