Input: Question: Who won the 1947 tournament that the IFA XI were runners up in? Passage 1:Hashimoto became a key figure in the strong LDP faction founded by Kakuei Tanaka in the 1970s, which later fell into the hands of Noboru Takeshita, who then was tainted by the Recruit scandal of 1988. In 1991, the press had discovered that one of Hashimoto's secretaries had been involved in an illegal financial dealing. Hashimoto retired as Minister of Finance from the Second Kaifu Cabinet. Following the collapse of the bubble economy, the LDP momentarily lost power in 1993/94 during the Hosokawa and Hata anti-LDP coalition cabinets negotiated by LDP defector Ichirō Ozawa. Hashimoto was brought back to the cabinet when the LDP under Yōhei Kōno returned to power in 1994 by entering a ruling coalition with traditional archrival Japanese Socialist Party (JSP), giving the prime ministership to the junior partner, and the minor New Party Harbinger (NPH). Hashimoto became Minister of International Trade and Industry in the Murayama Cabinet of Tomiichi Murayama. As the chief of MITI, Hashimoto made himself known at meetings of APEC and at summit conferences.
 Passage 2:In 1922, Heitler began his study of physics at the Karlsruhe Technische Hochschule, in 1923 at the Humboldt University of Berlin, and in 1924 at the Ludwig Maximilian University of Munich (LMU), where he studied under both Arnold Sommerfeld and Karl Herzfeld. The latter was his thesis advisor when he obtained his doctorate in 1926; Herzfeld taught courses in theoretical physics and one in physical chemistry, and in Sommerfeld's absence often took over his classes. From 1926 to 1927, he was a Rockefeller Foundation Fellow for postgraduate research with Niels Bohr at the Institute for Theoretical Physics at the University of Copenhagen and with Erwin Schrödinger at the University of Zurich. He then became an assistant to Max Born at the Institute for Theoretical Physics at the University of Göttingen. Heitler completed his Habilitation, under Born, in 1929, and then remained as a Privatdozent until 1933. In that year, he was let go by the university because he was Jewish.
 Passage 3:Between 1946 and 1950, Walsh made 11 appearances and scored seven goals for the IFA XI. These include two Victory internationals played in early 1946. On 2 February, at Windsor Park he made his debut for the IFA XI in a 3–2 defeat to Scotland, scoring both of his teams goals. Then, on 4 May, he helped the IFA XI defeat Wales 1–0 at Ninian Park. On 27 November 1946, he played for the IFA XI a 0–0 draw with Scotland. Together with Johnny Carey, Con Martin, Bill Gorman, Tommy Eglington, Alex Stevenson and Peter Farrell, he was one of seven players born in the Irish Free State to play for the IFA XI that day. The draw helped the team finish as runners-up in the 1947 British Home Championship. Walsh also helped the IFA XI gain some further respectable results, including a 2–0 win against Scotland on 4 October 1947 and a 2–2 draw with England at Goodison Park on 5 November 1947. It was at Goodison that Walsh scored his third goal for the IFA XI, in a game he was later to describe as the highlight of his footballing career.
