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 Schrodinger at the University of Zurich. He then became an assistant to Max Born at the Institute for Theoretical Physics at the University of Gottingen. 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 Ichiro Ozawa. Hashimoto was brought back to the cabinet when the LDP under Yohei Kono 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 long had he been king when Perseud led the Macedonians in the Third Macedonian War? Passage 1:1964 is a documentary film produced by Insignia Films for the American Experience series about political, social and cultural events in the United States for the calendar year 1964. It is based partly on Jon Margolis book The Last Innocent Year: America in 1964. The documentary depicts the year 1964 as significant and epic in that following the assassination of President John F. Kennedy in late 1963, 1964, as a presidential election year, becomes a departure point for American history, with lasting effects today. It is also the year of the British Invasion led by the Beatles, when Cassius Clay fights Sonny Liston for the World Heavyweight Championship, the year after Betty Friedan's book, The Feminine Mystique, is published, and the year Republican activist, Phyllis Schlafly's book, A Choice, Not an Echo, is published. It is also the year of Freedom Summer, an initiative by the Student Nonviolent Coordinating Committee to register African-Americans in Mississippi, the subsequent murders of Chaney, Goodman, and Schwerner, three CORE activists, in Mississippi by white supremacists that created a national sensation, and the Harlem riot of 1964, culminating in the Berkeley Free Speech Movement at the University of California at Berkeley. A recurrent theme of the film is its departure as a presidential election year, with President Lyndon B. Johnson running as the expected Democratic Party nominee and the nomination of U.S. Senator Barry Goldwater selected through a grassroots campaign for the Republican nomination for President of the United States, that defines the future divisions of the US political party competition.
Passage 2:The Battle of Callinicus () was fought in 171 BC between the Kingdom of Macedon and the Roman Republic near a hill called Callinicus, close to the Roman camp at Tripolis Larisaia, five kilometres north of Larissa, the capital of Thessaly. It was fought during the first year of the Third Macedonian War (171-168 BC). The Macedonians were led by their king, Perseus of Macedon, while the Roman force was led by the consul Publius Licinius Crassus. The Macedonians were supported by Cotys IV, the king of the Odrysian kingdom (the largest state in Thrace) and his forces, by Cretan mercenaries and by auxiliaries of mixed nationalities. The Romans had their Italian allies with them and were supported by soldiers provided by Eumenes II of Pergamon, as well as a force of Thessalian cavalry and Greek allies. The battle saw the deployment of troops with cavalry intermixed with light infantry. Although the battle was actually inconclusive because Perseus withdrew before it came to a conclusion, it was considered a Macedonian victory because the Romans suffered heavy casualties.
Passage 3:During the Napoleonic wars, Ile de France became a base from which the French navy, including squadrons under Rear Admiral Linois or Commodore Jacques Hamelin, and corsairs such as Robert Surcouf, organised raids on British merchant ships. The raids (see Battle of Pulo Aura and Mauritius campaign of 18091811) continued until 1810 when the British sent a strong expedition to capture the island. The first British attempt, in August 1810, to attack Grand Port resulted in a French victory, one celebrated on the Arc de Triomphe in Paris. A subsequent and much larger attack launched in December of the same year from Rodrigues, which had been captured a year earlier, was successful. The British landed in large numbers in the north of the island and rapidly overpowered the French, who capitulated (see Invasion of Isle de France). In the Treaty of Paris (1814), the French ceded Ile de France together with its territories including Rodrigues and Seychelles to Great Britain. The island then reverted to its former name, 'Mauritius'.

Question: The player that replaced Hacker of the 40-man roster of the twins had how many wins in his big league career? Passage 1:On November 9, 2010, Hacker signed with the Minnesota Twins. He attended spring training but was sent to the minors after posting a 13.50 ERA in five games. He was called up to Minnesota on April 19 to replace Alex Burnett (who was optioned) in the bullpen; Twins manager Ron Gardenhire said, "We need a long guy [in the bullpen]." He made his Twins' debut that day, throwing two scoreless innings in an 110 loss to the Baltimore Orioles. In his next game on April 27, he gave up one unearned run in innings but allowed three inherited runners to score in an 82 loss to the Tampa Bay Rays. After the game, Hacker was optioned back to Triple-A Rochester to make room on the roster for Anthony Swarzak. On July 17, he was outrighted off the 40-man roster to make room for Scott Diamond. With the Rochester Red Wings of the International League, Hacker had a 714 record, a 6.10 ERA, 98 strikeouts, 50 walks, and innings pitched in 26 games (25 starts). He tied with Diamond for the league lead in losses, ranked sixth in the league in walks, led the league in runs allowed (103), and ranked third in the league in earned runs allowed (92, behind Thad Weber's 95 and Corey Kluber's 93). On October 4, he became a free agent.
Passage 2:After his term as consul, Didius was assigned to govern the province of Hispania Citerior, where he served from 97 BC to 93 BC. Nearly his entire proconsular term in Spain was spent at war with the Celtiberi. In the four years Didius governed Spain he achieved multiple victories and is said to have slain 20,000 Arevaci, quelled the rebellious city of Termes (today Tiermes in the province of Soria), and besieged Colenda for nine months, after which time the city fell and the women and children were sold into slavery. Didius earned another triumph after slaughtering a colony of "robbers" -- in actuality, poor people who had banded together to subsist through banditry after losing their property. Didius lured them in with promises of land to live on, and when the families assembled within the Roman castra in good faith, he had them all killed. The historian Appian indicates that Didius's exceptional cruelty and treachery caused an even greater uprising which his experienced successor, C. Valerius Flaccus, had to put down.

He received honorary Doctor of Law degrees from the University of Missouri (1933); Syracuse University (1934); and Harvard University (1951). Robert Bliss was one of five retired diplomats who co-signed a 1954 letter protesting U.S. Senator Joseph McCarthy's attacks on the Foreign Service.
