Question: How old was King Henry's eldest daughter when the search for a queen for James began? Passage:Forman and Bishop William Elphinstone of Aberdeen were the principal envoys who brokered a seven-year truce with King Henry VII of England at Aytoun in September 1497. They were assisted by the Spanish ambassador Pedro de Ayala, who recommended in May 1498 that diplomatic correspondence to Scotland should be copied to Forman, his influential friend. The search for a queen for James began in 1499 when negotiators were appointed to treat with King Henry for the marriage of his eldest daughter, Princess Margaret. Dispensation from the pope for the marriage was received as both James and Margaret were cousins, descended from John Beaufort, Marquess of Dorset. On 8 October 1501, Forman, now postulate to the see of Moray, was commissioned along with Robert Blackadder, Archbishop of Glasgow and Patrick Hepburn, 1st Earl of Bothwell to conclude the treaty of marriage. In that same year, King Henry, in gratitude for his services required that Thomas Savage, Archbishop of York institute Forman as Rector of the parish church of Cottingham. On 26 November 1501, Pope Alexander VI provided Forman to the bishopric of Moray and then only a few months later in 1502, Bishop Forman concluded the Treaty of Perpetual Peace with England at Richmond Palace. The formal proceedings that finally concluded the marriage terms of King James and Margaret Tudor were conducted in Glasgow Cathedral on 10 December 1502 where Forman was a signatory. He was then appointed as a commissioner to oversee the exchange of the ratified marriage treaties at the courts of Henry and James. James designated Forman to conduct Margaret to Scotland but while in England, gave King Henry an undertaking that the King of Scots would not renew the league with France unless Henry was first consulted. The procession to Scotland took them to Fast Castle near Berwick where they stayed with Forman's sister Isabel and her husband Alexander Oliphant of Kellie. In 1509, Forman became commendator of Dryburgh Abbey and tried unsuccessfully to obtain the commendatorship of the wealthy abbey of Kelso in 1511. The lands and possessions of the parson of Boleskin, south of Inverness were given to Forman (as bishop of Moray) in 1511 and then in 1512 he became the Keeper of the castle of Darnaway, near Forres, Chamberlain of Moray and Custumar north of the River Spey.

Question: When did Wayne Rooney start playing professionally? Passage:Arsenal had finished the previous season as runners-up in the Premier League, overhauled by Manchester United in the final ten weeks of the season. The club did, however, retain the FA Cup, with a 10 win against Southampton. Such was Arsenal's effective start to the 200203 campaign, manager Arsene Wenger suggested his team could remain the whole season undefeated in all competitions:It's not impossible as A.C. Milan once did it but I can't see why it's so shocking to say it. Do you think Manchester United, Liverpool or Chelsea don't dream that as well? They're exactly the same. They just don't say it because they're scared to look ridiculous, but nobody is ridiculous in this job as we know anything can happen. The team lost to Everton a month after Wenger's proclamation; teenager Wayne Rooney scored the match winner, which ended a run of 30 league games without defeat. By February 2003, Arsenal moved five points clear of Manchester United at the top of the league table, but injuries to key players, not least captain Patrick Vieira, had destabilised the team. Draws in April, coupled with a defeat to Leeds United at home, mathematically ended Arsenal's chances of retaining the title. Wenger refuted opinions from the media that their season was a failure and said:
