Input: Consider Input: Question: Of the two colonies captured by Philip, which one was established first? Passage:Athens and Macedon had been at war since 356 BC, after Philip's capture of the Athenian colonies of Pydna and Potidea. Shortly afterwards, the Third Sacred War began after the Phocian seizure of the Temple of Apollo in Delphi. Athens allied herself with Phocis, against the other members of the Amphictyonic League. In 354 or 353 BCE, the Thessalians, having been defeated by the Phocians, requested that Philip become archon of Thessaly, to which Philip assented, drawing Macedon into the Sacred War. In 352 BC, Philip's erstwhile ally, the Chalkidian League (led by Olynthos), alarmed by Philip's growing power, sought to ally themselves with Athens, in clear breach of their alliance with Philip. In response, Philip attacked Chalkidiki in 349 BC, and by 348 BC, had completely destroyed the Chalkidian League, razing Olynthos in the process.

Input: Consider Input: Question: In what state did McAtee play professional hockey in the NHL? Passage:Norman Joseph McAtee (June 28, 1921 – August 25, 2010) was a professional ice hockey player who played 13 games in the National Hockey League with the Boston Bruins. Born in Stratford, Ontario, he and his brother Jud played together in junior ice hockey with the Oshawa Generals during the years when the Generals dominated the Ontario Hockey League, winning championships with them in 1938–39. 1939–40 and 1940–41. At the end of the 1941 season, Norm joined his brother by signing as a free agent with the Detroit Red Wings in the NHL. However, beginning in 1942 and lasting throughout World War II, Norm became a flying officer in the Royal Canadian Air Force. After his discharge in 1945, he teamed with his brother in the Red Wings farm system before the two of them were traded to the Chicago Blackhawks for Doug McCaig in December 1945. Just over a month later, Chicago traded him to Boston for Bill Jennings, and Norm joined the Bruins for 13 games, recording one assist. After that, he finished his career in the minor leagues, ending as player-coach with the Troy Bruins in Troy, Ohio from 1951 to 1954.

Input: Consider Input: Question: Which team won the 2004-2005 UEFA Champions League? Passage:Park began his football career in his native South Korea and played for the Myongji University team before moving to Japan to play for Kyoto Purple Sanga. After Park's national team manager Guus Hiddink moved back to the Netherlands to manage PSV Eindhoven, Park followed him to the Dutch side a year later. After PSV reached the semi-finals of the 2004–05 UEFA Champions League, Park's talents were recognised by Manchester United manager Sir Alex Ferguson and he signed Park for a fee of around £4 million in July 2005. In his time at United, Park won the Premier League four times and also won the 2007–08 UEFA Champions League and the 2008 FIFA Club World Cup. He moved to Queens Park Rangers in July 2012 after suffering a reduction in his number of appearances for Manchester United the previous season. However, an injury-interrupted season with QPR, combined with the club's relegation, led to Park rejoining PSV on loan for the 2013–14 season.
