Question: How old was Ferdinand I when Henry II signed the Treaty of Chambord? Passage 1:Askey was a youth-team player at Port Vale, the club where his father, Colin Askey, made over 200 appearances in the 1950s. Despite winning the club's Young Player of the Year award in 1982, he was never handed a first-team debut at Vale Park. After leaving the club he spent a year working as a laborer for a pottery firm in Tunstall, before entering the insurance industry. He first joined Macclesfield Town from Milton United in 1984, alongside his brother Bob, to fill a gap when the club were short of players. He scored on his debut during the 1984–85 season, coming on as a substitute away at Morecambe on 29 December. He went on to score one goal in three appearances as the "Silkmen" finished as runners-up to Stafford Rangers in the Northern Premier League. He featured 13 times in the 1985–86 campaign, before scoring seven goals in 17 appearances as Macclesfield won the Northern Premier League title in 1986–87. Macclesfield went on to secure a treble after winning the Northern Premier League President's Cup and beating Burton Albion 2–0 in the Northern Premier League Challenge Cup final at Maine Road.
 Passage 2:Thomas Bonham had been admitted to St John's College, Cambridge, in 1581. Earning a bachelor's degree in 1584, he completed a master's by 1588 and studied for a medical doctorate at Cambridge, which was later granted by the University of Oxford. By 1602, he had completed his studies and moved to London, where he practised medicine and associated himself with the Barber-Surgeons' Company, campaigning for it to be allowed to authorise medical practitioners in a similar way to the College of Physicians. Apparently giving up after a failed petition to Parliament in 1605, Bonham petitioned to join the college on 6 December 1605 but was rejected and told to return after further study. Returning on 14 April 1606, he was again told he could not join and was fined £5 () and threatened with imprisonment for continuing to practise. Bonham still kept working as a doctor; on 3 October it was announced he was to be arrested and fined £10. Bonham again appeared before the college, now with a lawyer, on 7 November. He announced that he would continue to practise without seeking the college's permission, which he claimed had no power over graduates of Oxford or Cambridge. He was then imprisoned (some say at Fleet Prison, and some say at Newgate Prison) for contempt, but his lawyer had a writ of habeas corpus, issued by the Court of Common Pleas, which freed him on 13 November.
 Passage 3:Dissatisfied with the Interim decreed by Charles V at the 1548 Diet of Augsburg, the insurgents were full of resolution to defend Protestantism and–not least–their autonomy against the Imperial central authority. They agreed to establish contacts with the Catholic French king Henry II, disregarding his oppression of the Protestant Huguenots. In autumn Henry declared war against Charles V and prepared to march against the Empire up to the Rhine River. On 15 January 1552, he signed the Treaty of Chambord with Maurice of Saxony and his Protestant allies, whereby the French conquests were legitimised ahead of time. The princes acknowledged the king's lordship as "Vicar of the Empire" over the Imperial cities of Metz, Toul and Verdun, as well as Cambrai "and other towns of the Empire that do not speak German". The insurgents in turn received subsidies and military assistance from the French, their troops moved into the Habsburg hereditary lands and laid siege to the emperor at Innsbruck, while his brother Ferdinand I entered into negotiations that led to the revocation of the Augsburg Interim by the 1552 Peace of Passau.
