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.

Question: Which of the teams Boswell played for was the oldest? Passage:Born in Chester, Boswell joined local football club Chester F.C. upon leaving school, initially as an amateur. He remained with the club until the outbreak of the Second World War, but never made it to the club's first team. During the war he served with the Royal Engineers and also made appearances as a guest player for Sheffield Wednesday during unofficial wartime competitions. He was later posted to Barton Stacey in Hampshire, where he helped his unit's football team win a major Army Football Association trophy. Upon leaving the army in 1946 he joined Gillingham, who at the time were playing in the Kent League. Gillingham manager Archie Clark also signed four other players who had served with Boswell at Barton Stacey and played alongside him in the unit football team, namely Jackie Briggs, George Forrester, Hughie Russell and Vic Hole.

Question: Who managed the team that the Royals were runners-up to in the 2001-02 season? Passage:Dillon returned to Reading in 1995 and held a number of roles within Reading's academy. He was also reserve team manager before he replaced Martin Allen as Alan Pardew's assistant in November 2001. Under the guidance of the management duo, the Royals were promoted to Division 1 after finishing as runners-up to Brighton & Hove Albion in the 2001–02 season. Pardew resigned in September 2003 and Dillon stepped in as the caretaker manager, until Steve Coppell was appointed in October 2003. At this point Dillon reverted to his role as the number two. Dillon passed his UEFA Pro Licence in 2004 and in the 2005–06 season Reading won the Championship with a record of 106 points. In their first season in the Premier League Reading finished 8th. In May 2007, Dillon followed Coppell's lead in committing himself to Reading for a further two seasons. They were relegated back to the Championship the next season and in May 2009 following the resignation of Coppell, Dillon alongside other first-team coach Wally Downes, left Reading following the team's failure to gain promotion back to the Premier League.
