Teacher: Now, understand the problem? Solve this instance: Question: How many La Liga championships has Valencia won? Passage 1:Casillas began his career in Real Madrid's youth system, known as La Fábrica, during the 1990–91 season. On 27 November 1997, at age 16 and still a junior, he was first called up to the senior team squad to face Rosenborg in the UEFA Champions League, although he remained on the bench throughout. After spending a season with the C-team in the fourth tier, during which they won their regional group, he came into contention as the club's first-choice between the posts. In starting the 1999–2000 UEFA Champions League group stage fixture against Olympiakos on 15 September 1999, he became the youngest goalkeeper ever to feature in the competition at the time, aged 18 years and 177 days; a record which was only broken in October 2017 by Mile Svilar. Three days earlier, Casillas had made his La Liga debut in a 2–2 draw against Athletic Bilbao at San Mamés Stadium. In May 2000, he became the youngest ever goalkeeper to play in and win a Champions League final when Real Madrid defeated Valencia 3–0, just four days after his 19th birthday.
 Passage 2:On 21 November, Vale picked up their third league win of the campaign, beating lowly Barnsley 2–0 at Oakwell. Youth players continued to be drafted in as Vale finished the year with four straight league defeats, picking up injuries and sendings off along the way. In December, Hancock was sold to Ipswich Town for £10,000. A 2–1 victory over promotion-chasers Brentford on 2 January failed to spark a revival, partly due to the fact that the Bees were forced to play almost the entire match with ten players and an outside player in goal following an injury to Chic Brodie. Steele tried to play a settled team, but that proved to be as unsuccessful as when he switched the team round constantly. By the end of the month the club were bottom of the league and morale was low. In mid-February, the club four points short of safety, Steele left the club 'by mutual consent', as Jackie Mudie was appointed caretaker manager. Following a 4–0 hammering from Gillingham, Mudie signed veteran stopper Jimmy O'Neill from Darlington, and the former Ireland international seemed to improve the team, as just two defeats in eight games followed. Mudie instilled discipline into the team, and so was made manager on a permanent basis on 3 March. He then ensured Reg Davies was transferred to Leyton Orient. He tried and failed to re-sign Terry Harkin from Crewe Alexandra. One win in their final six games doomed the Vale to relegation, just as survival seemed possible. Only 3,521 witnessed a final day victory over Walsall.
 Passage 3:He played the role of Loge in Richard Wagner's Das Rheingold at Munich Court Opera on September 22, 1869, with his wife, Therese Vogl, playing the role of Wellgunde. He also played the role of Siegmund in Wagner's Die Walküre, also at Munich, on June 26, 1870. Therese Vogl played the role of Siegmund's sister and lover Sieglinde in the same performance. His Munich debut was as Max in Weber's Der Freischütz. He sang at Bayreuth, Berlin, London and the Metropolitan Opera in New York City. At Bayreuth, he played the role of Loge in the first complete Ring cycle on August 13, 1876. His performance in the role caused fellow singer Lilli Lehmann to comment that he was born for the part and that his Loge had never been equalled. His debut at the Metropolitan Opera was in the title role of Lohengrin on January 1, 1890, and he also sang Loge, Siegmund, the title role of Tannhäuser, Tristan in Tristan und Isolde, and Siegfried in both Siegfried and Götterdämmerung at the Met. Heinrich Vogl was also the first performer to play the roles of Loge and Siegfried in London, which he did in the first Ring cycle in London at Her Majesty's Theatre, with Anton Seidl conducting and his wife playing the role of Brünnhilde.
