Input: Consider Input: Question: How big was the Royal Air Force the year York joined Aston Villa? Passage:York started his career with Handsworth Royal, Birchfield Rangers and the Royal Air Force, and also guested for Chelsea during World War I. In March 1915 he joined Aston Villa as an amateur, signing professional forms in August 1919. He scored one goal in 17 games in 1919–20, but did not feature in the 1920 FA Cup Final, which ended in a 1–0 victory over Huddersfield Town at Stamford Bridge. He appeared just 11 times in 1920–21, before going on to make 47 appearances in the 1921–22 campaign, as the "Villans" finished fifth in the First Division. He scored nine goals in 37 games in 1922–23 and five goals in 43 games in 1923–24. He also appeared at Wembley in the 1924 FA Cup Final, in a 2–0 defeat to Newcastle United. He scored seven goals in 34 matches in 1924–25, before hitting 20 goals in 44 appearances in 1925–26. He bagged 13 goals in 43 games in 1926–27, before being limited to just four goals in 30 appearances in 1927–28. He rediscovered his scoring form with 18 strikes in 48 matches in 1928–29, before hitting seven goals in 32 games in 1929–30. However he played just four times in the 1930–31 campaign, as Villa finished second in the league with an English record of 128 top-flight league goals scored.

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: Who was the initial ruler of Fiji when it was an independent kingdom? Passage:The majority of Fiji's islands formed through volcanic activity starting around 150 million years ago. Some geothermal activity still occurs today, on the islands of Vanua Levu and Taveuni. The geothermal systems on Viti Levu are non-volcanic in origin, with low-temperature (c. 35–60 degrees Celsius) surface discharges. Sabeto Hot Springs near Nadi is a good example. Humans have lived in Fiji since the second millennium BC—first Austronesians and later Melanesians, with some Polynesian influences. Europeans visited Fiji from the 17th century onwards, and, after a brief period as an independent kingdom, the British established the Colony of Fiji in 1874. Fiji operated as a Crown colony until 1970, when it gained independence as the Dominion of Fiji. A military government declared a Republic in 1987 following a series of coups d'état. In a coup in 2006, Commodore Frank Bainimarama seized power. When the High Court ruled the military leadership unlawful in 2009, President Ratu Josefa Iloilo, whom the military had retained as the nominal Head of State, formally abrogated the 1997 Constitution and re-appointed Bainimarama as interim Prime Minister. Later in 2009, Ratu Epeli Nailatikau succeeded Iloilo as President. After years of delays, a democratic election took place on 17 September 2014. Bainimarama's FijiFirst party won 59.2% of the vote, and international observers deemed the election credible.
