Input: Question: How many teams played in the Malaysia Premier League the year Ferns made his debut for Felda United? Passage 1:At the beginning of the ninth century, England was almost wholly under the control of the Anglo-Saxons. The Midland kingdom of Mercia dominated southern England, but their supremacy came to an end in 825 when they were decisively defeated by Ecgberht at the Battle of Ellendun. The two kingdoms became allies, which was important in the resistance to Viking attacks. In the same year Ecgberht sent his son Æthelwulf to conquer the Mercian sub-kingdom of Kent (the area of the modern county plus Essex, Surrey and Sussex) and appointed him sub-king. In 835 the Isle of Sheppey was ravaged by Vikings and in the following year they defeated Ecgberht at Carhampton in Somerset, but in 838 he was victorious over an alliance of Cornishmen and Vikings at the Battle of Hingston Down, reducing Cornwall to the status of a client kingdom. He died in 839 and was succeeded by Æthelwulf, who appointed his eldest son Æthelstan as sub-king of Kent. Æthelwulf and Ecgberht may not have intended a permanent union between Wessex and Kent as they both appointed sons as sub-kings and charters in Wessex were attested (witnessed) by West Saxon magnates, while Kentish charters were witnessed by the Kentish elite; both kings kept overall control and the sub-kings were not allowed to issue their own coinage.
 Passage 2:Ferns made his debut for Felda United F.C. in the Malaysia Super League with a 2-1 win against Pahang FA in July 2017. Under the guidance of head coach B. Sathianathan, Ferns made a successful contribution, helping the team reach 3rd place in the Malaysia Super League and semi-final of the Malaysia Cup. Unfortunately, in the off-season of 2017 the club was notified it was being relegated to the Malaysia Premier League for the 2018 season after failing the Football Association of Malaysia club licence financial audit. Despite this setback, Ferns and the majority of the squad stayed at the club to help Felda United F.C win the title and secure promotion back to the Malaysia Super League for 2019. 
 Passage 3:Denard Robinson became the first major-college quarterback to throw and rush for 1,500 yards in one season. He also went on to set the Big Ten Conference single-season rushing yards by a quarterback record and was named a Davey O'Brien Award semifinalist. In November, he was also named as one of sixteen Maxwell Award semifinalists. Center David Molk was a finalist for the Rimington Trophy. Michigan had three individual statistical champions for conference game statistics: Denard Robinson averaged 317.5 yards of total offense per game, wide receiver Roy Roundtree averaged 83.9 receiving yards per contest and punter Will Hagerup averaged 46.0 yards per punt. They also had three champions for all games: Robinson 130.9 rushing yards per game and 328.6 average yards of total offense, while Jonas Mouton recorded 9.8 tackles per game. Denard Robinson was also named the Big Ten Offensive Player of the Year. In addition, the following other players were selected to the All-Big Ten Conference team: Denard Robinson (1st team – media, honorable mention – coaches), Molk (1st team – media & coaches), Mike Martin (2nd team – coaches, honorable mention – media) Mouton (2nd team – media), Roundtree (2nd team – media), Stephen Schilling (honorable mention – coaches & media), and Jordan Kovacs (honorable mention – media).
