Question: Did the man who founded the strong LDP faction and the man whose hands it later fell into both serve as Prime Minister of Japan? Passage 1: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 2: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.

Question: How many wins did Felda United achieve the year Ferns debuted with them? Passage 1: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 2: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 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.

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.

Question: How old was the newcomer when it was announced she had been cast for the role of an impressionable Southern girl? Passage 1:On March 8, 2017, it was announced that 20th Century Fox had bought the spec script Bad Times at the El Royale, written by Drew Goddard, who would also direct and produce the film. On August 23, 2017, Chris Hemsworth and Jeff Bridges were cast in the 1960s-set film, to play two among the several characters who collide at the El Royale hotel, near California's Lake Tahoe. That same day, it was also reported that Tom Holland had passed on a role, and that Beyoncé was being courted for the role of a Black vocalist. It was also revealed that main roles in the ensemble would include a vacuum cleaner salesman, two female criminals, a male cult leader, and a desk clerk. Later in August 2017, newcomer Cailee Spaeny was added to the cast to play an impressionable Southern girl brought to the hotel, while Cynthia Erivo was cast as the Black singer who finds herself in the wrong place at the wrong time. In January 2018, Dakota Johnson and Russell Crowe joined the cast (though Crowe did not appear in the film). In February 2018, Jon Hamm, Nick Offerman, and Mark O'Brien joined the cast, and in May 2018, Lewis Pullman was also confirmed for a role.
 Passage 2:Southern Utah has the densest population of slot canyons in the world with over one thousand slot canyons in the desert lands south of Interstate 70. Utah's slot canyons are found in Zion National Park at The Narrows, along Canyonlands National Park's Joint Trail, throughout Capitol Reef National Park, within the San Rafael Swell and the Grand Staircase-Escalante National Monument, especially along the Escalante River drainage including Coyote Gulch. Many more slot canyons are located on public Bureau of Land Management and state-owned lands in southern Utah, in areas surrounding the aforementioned parks and monuments. Buckskin Gulch—one of the longest slot canyons in the world—begins in southern Utah and continues into northern Arizona within the Paria Canyon-Vermilion Cliffs Wilderness. Northern Arizona also has a high concentration of slot canyons including Antelope Canyon and Secret Canyon, which are two of the most famous slot canyons located near Page on land owned by the Navajo Nation. Slot canyons are also located in the valley between U.S. Route 89 and the Vermilion Cliffs in Arizona, and can be seen as one descends into the valley on U.S. 89, but these are on the Navajo reservation and are closed to the public. The Kasha-Katuwe Tent Rocks National Monument's slot canyon trail in New Mexico is unique as it was carved into tuff (volcanic ash). In California, several slot canyons are located within Death Valley National Park.
 Passage 3:The film was only a modest hit when first released. O'Connor won the Golden Globe Award for Best Actor – Motion Picture Musical or Comedy, and Betty Comden and Adolph Green won the Writers Guild of America Award for their screenplay, while Jean Hagen was nominated for the Academy Award for Best Supporting Actress. However, it has since been accorded legendary status by contemporary critics, and is frequently regarded as the best film musical ever made, and the best film ever made in the "Freed Unit" at Metro-Goldwyn-Mayer. It topped the AFI's Greatest Movie Musicals list and is ranked as the fifth-greatest American motion picture of all time in its updated list of the greatest American films in 2007. In 1989, the United States Library of Congress selected the film for preservation in the National Film Registry. In 2005 the British Film Institute included it in its list of the 50 films to be seen by the age of 14. In Sight & Sound magazine's 2017 list of the 50 greatest films of all time, Singin' in the Rain placed 20th.
