Input: Consider Input: Question: Was Viborg Ff still operational when Burns earned a place in his first All-Star game? Passage:In 1995, the MLS began an expansion plan to add new teams to the league. In the 1996 MLS Inaugural Allocations, the MLS assigned Burns to the New England Revolution. In August 1995, the MLS loaned out Burns to Danish club Viborg FF. The Revolution retained his rights and Burns returned to play for the Revolution in 1996. In 1998, Burns earned a place in the MLS All-Star game. In the 1999 off-season, he made several attempts to move back to a European club, trying out with clubs such as Utrecht, Bolton and Hearts. None of the clubs expressed interest in him and Burns returned to the Revolution. In June 2000, the Revolution traded Burns, Dan Calichman and a first round draft pick to the San Jose Earthquakes in exchange for Mauricio Wright. Burns finished the 2000 season with the Earthquakes. However, he did not remain with the team and he was traded in March 2001 to the Kansas City Wizards in return for conditional picks in the 2002 MLS SuperDraft. Burns played two seasons with the Wizards, 2001 and 2002. In 2002, he was chosen to play in the 2002 MLS All-Star Game. At the end of the 2002 season, Burns announced his retirement from professional football.

Input: Consider Input: Question: How old was Waledynski when the autocephaly he requested was finally granted? Passage:The establishment of the church was undertaken after the Treaty of Riga left a large amount of territory previously under the control of the Russian Empire, as part of the Second Polish Republic. Eastern Orthodoxy was widespread in the Belarusian Western Belarus regions and the Ukrainian Volhynia. The loss of ecclesiastical link due to the persecution of the Russian Orthodox Church in the Soviet Union, left the regional clergy in a crisis moment, and in 1924, the Ecumenical Patriarchate took over establishing several autonomous churches on territories of the new states that were formerly wholly or partially part of the Russian Empire (Finland, the Baltic States, and Poland). Earlier, in January 1922, the Polish government had issued an order recognizing the Orthodox church and placing it under the authority of the state. At that time a Ukrainian, Yurii Yaroshevsky, was appointed Metropolitan and exarch by the patriarch of Moscow. When Yaroshevsky began to reject the authority of Moscow Patriarchate, he was assassinated by a Russian monk. Nonetheless, his successor, Dionizy Waledynski (Dionisii Valedinsky), continued to work for the autocephaly of the Polish Orthodox church, which was finally granted by the Ecumenical Patriarch of Constantinople in his Tomos of 13 November 1924. Given that most of the parishioners were Ukrainians and Belarusians living in the Eastern areas of the newly independent Polish Second Republic, the Patriarch of Constantinople had a canonical basis to grant the Tomos to the Polish church as a successor of the Kyiv Metropolia, the former territory of Kyivan Rus' which Constantinople continued to see as its canonical territory (despite having agreed to allow Moscow to be its caretaker it in 1686). The Russian Orthodox Church at the time did not recognise the Polish autocephaly, as it did not recognise the autocephaly of the Orthodox Church of the Czech Lands and Slovakia.

Input: Consider Input: Question: What date did the Scorpions release the album the album producered Mikael Nord Andersson and Martin Hansen? Passage:In 2010, the Scorpions announced their farewell tour. Before they retire, they wanted to release a bonus track album from leftovers from seventies and eighties just for the fans. After playing the final show in Munich in December, 2012, band planned to take a break and go on vacation. In January, 2013, MTV contacted the band and asked if they are interested in doing the MTV Unplugged album. They agreed on doing that project and turned out to be successful. That whole thing pushed back the bonus track project. As soon as they have finished the MTV Unplugged project, band immediately went back to studio to work on bonus track project. Band was listening the recordings they have already prepared for the project. They were happy with the result and Rudolf Schenker said that he has a tape with some songs that they could also use for this project. While searching for the tape, Schenker found an old ledger in which his mother enumerated the loans that his father provided to him, so he could buy all the equipment and establish the band. He looked into the book and it said: "September, 1965". He went back to the studio and told the band what he found and their manager said that it would be great idea to celebrate 50th Anniversary since they are the only German band who is 50 years in music and one of the few in the world along with The Rolling Stones, The Who, Beach Boys and Pink Floyd. Manager suggested to the band that they contact the promoters and see if they are interested in band doing the 50th Anniversary Tour. Then Schenker suggested that if band is going to do a 50th Anniversary Tour, then band needs to release brand new studio album. So the band went again into the listening process of bonus track material that they have already prepare and see if they can improve something, like choruses and riffs. After that, they re-recorded the old stuff and started to write new songs with the producers Mikael Nord Andersson and Martin Hansen. The result was the album Return to Forever.
