Problem:Question: In what country was the battle fought in which King Louis II died? Passage 1:As the Turkish incursion into Europe started, Croatia once again became a border area. The Croats fought an increasing number of battles and gradually lost increasing swathes of territory to the Ottoman Empire. Ottoman conquests led to the 1493 Battle of Krbava field and 1526 Battle of Mohacs, both ending in decisive Ottoman victories. King Louis II died at Mohacs, and in November 1526, a Hungarian parliament elected Janos Szapolyai as the new king of Hungary. In December 1526, another Hungarian parliament elected Ferdinand Habsburg as King of Hungary. On the other side, the Croatian Parliament met in Cetin and chose Ferdinand I of the House of Habsburg as new ruler of Croatia, under the condition that he provide protection to Croatia against the Ottoman Empire while respecting its political rights. A few years later both crown would be again united in Habsburgs hands and the union would be restored. The Ottoman Empire further expanded in the 16th century to include most of Slavonia, western Bosnia (then called Turkish Croatia) and Lika. Ottoman Croatia initially was part of Rumelia Eyalet, and later was parts of Budin Eyalet, Bosnia Eyalet and Kanije Eyalet.
Passage 2:Harrison signed for Stevenage in January 2011 on a free transfer and was handed the number 26 shirt. As part of the deal, Carshalton played host to Stevenage in a friendly in July 2011. Harrison played his first game for the club shortly after, starting in Stevenage's 10 away loss to Gillingham. He scored his first goal for Stevenage in the club's 30 home win against Rotherham United on 25 January 2011, scoring just three minutes after coming on as a substitute to give Stevenage a two-goal lead. A week later, in his next game, Harrison scored twice in Stevenage's 22 draw with Gillingham. Harrison scored his fourth goal in as many games in another 22 draw, scoring the first goal of the game against Accrington Stanley with a looping shot from outside the area. He scored his fifth goal for the club in Stevenage's 10 away win at Crewe Alexandra. The goal had initially been credited to Stevenage left back Scott Laird, but it was later announced that the ball had gone in off of Harrison's back. Harrison made it seven goals in eleven games after scoring two goals against Cheltenham Town on 26 February 2011. His eighth goal of the season came in the club's 22 home draw against Aldershot Town, with Harrison prodding Luke Foster's shot into the goal to earn Stevenage a point. Similarly to Harrison's goal against Crewe, the goal was originally given to another Stevenage player, this time Foster being credited with the goal, but the goal was officially given to Harrison a week later. Harrison finished the season as joint top goalscorer for Stevenage with eight goals in 23 appearances. This included three substitute appearances in the 201011 League Two play-offs following Stevenage's sixth-placed finish. After a 30 aggregate victory over Accrington Stanley, Stevenage earned promotion to League One courtesy of a 10 win against Torquay United at Old Trafford in the Final on 28 May 2011, with Harrison coming on as 62nd-minute substitute.
Passage 3:The following year Mount appeared in two films: she played Police Sergeant Fire in Dry Rot, an adaptation of a Whitehall farce, and she reprised the role of Emma Hornett in a film version of Sailor Beware!. Over the rest of the 1950s her career included stage, cinema and television work. She played the cameo role of the Charwoman in Diego Fabbri's religious drama Man on Trial at the Lyric Theatre, London in 1957. In the same year she starred with Terry-Thomas and Peter Sellers in the comedy film The Naked Truth. From 1958 onwards she became a regular television performer, first, opposite Richard Hearne, as a landlady in The Adventures of Mr. Pastry, and then in a central role in The Larkins, an early ITV comedy series featuring David Kossoff and Mount as a suburban London couple, Alf and Ada Larkin, and their family. Six series of the show were made between 1958 and 1964, and the leading characters, the put-upon but wily Alf and the formidable Ada, appeared in three spin-off feature films between 1958 and 1960. In a 1958 television version of Arsenic and Old Lace Mount was cast against type in the role of the well-meaning poisoner Abby Brewster. Her last stage role of the 1950s was Florence Povis in Farewell, Farewell, Eugene at the Garrick Theatre in June 1959, co-starring with Margaret Rutherford.
