Question: What is the birthplace of the man who revealed that Trnka was the composer of works previously attributed to Mozart? Passage 1:Trnka emerged into public view in 1988 when it was revealed by Wolfgang Plath that he was the composer of two minor works previously attributed to Wolfgang Amadeus Mozart. Trnka's compositional specialization appears to have been canons, a form of music at the time often sung recreationally among friends. According to Link, at least 61 canons by Trnka survive, and all but one are to lyrics by the famous librettist Metastasio. Mozart enjoyed singing canons with his friends (see "Difficile lectu"), and particularly liked canons with humorous scatological lyrics, of which he composed several himself (see Mozart and scatology). In the present case, Mozart evidently took two canons by Trnka and gave them new lyrics, which he probably wrote himself. Trnka's "Tu sei gelosa, è vero" became Mozart's "Leck mir den Arsch fein recht schön sauber" ("Lick me in the ass right well and clean"), and Trnka's "So che vanti un cor ingrato" became Mozart's "Bei der Hitz im Sommer eß ich" ("In the heat of summer I eat"). These works were mistaken as Mozart's compositions when his widow Constanze sent them as part of a bundle of canons in 1800 to the publisher Breitkopf & Härtel, who four years later duly published them as Mozart's work. They entered the standard Köchel catalogue as K. 233 and K. 234 (K 382e).
 Passage 2:He attended De La Salle College, Mangere East, and started his rugby league career with the Papatoetoe Panthers, later moving to Otahuhu, and playing in Auckland Rugby League competitions. As a member of Otahuhu, Ah Mau played for the Tamaki Titans in the Bartercard Cup. Ah Mau played for the Junior Kiwis in 2006 and the New Zealand under-18 side in 2007. Ah Mau was signed to a developmental contract with the Warriors in 2007. During his first year with the club he played 18 games in the NSWRL Premier League for the Auckland Lions. In 2008 he played in the inaugural season of the Toyota Cup, making 22 appearances for the Junior Warriors. He finished his Toyota Cup career with 40 appearances, 9 tries and 1 goal.
 Passage 3:The American Football Association (AFA) was the first attempt in the United States to form an organizing association football body. It is best known for being the second oldest sports league to form, behind the National League of baseball in 1876, as well as being the oldest association football league in the United States. The Association was formed in 1884 in an attempt to standardise rules and procedures. It was allied with The Football Association, becoming a member on 22 February 1909, at an FA meeting chaired by Charles Clegg, and drew on that organisation's approach to the game. As part of its efforts, the AFA directly organized both league and cup competitions as well as overseeing the operations of member leagues. In 1884, it established the American Cup, which for several decades was the highest competitive soccer competition in the United States. The weakness of the AFA lay in its refusal to expand outside the southern New England region. When a movement began to create a national governing body in 1911, the AFA found itself confronting the newly established American Amateur Football Association (AAFA), a body which quickly became national. The AFA argued that it should be recognized by FIFA. However, several member organizations defected from the AFA to the AAFA in 1912. The AAFA quickly moved to reform itself as the United States Football Association, receiving FIFA recognition in 1913. The AFA continued to run the American Cup until 1925, but by that time it had been superseded by the National Challenge Cup and National Amateur Cup.
