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: What were the factions in the 1975 civil war? Passage 1:The 84th Regiment of Foot (Royal Highland Emigrants) was a British regiment in the American Revolutionary War that was raised to defend present day Ontario, Quebec and Atlantic Canada from the constant land and sea attacks by American Revolutionaries. The 84th Regiment was also involved in offensive action in the Thirteen Colonies; including North Carolina, South Carolina, Georgia, Virginia and what is now Maine, as well as raids upon Lake Champlain and the Mohawk Valley. The regiment consisted of 2,000 men in twenty companies. The 84th Regiment was raised from Scottish soldiers who had served in the Seven Years' War and stayed in North America. As a result, the 84th Regiment had one of the oldest and most experienced officer corps of any regiment in North America. The Scottish Highland regiments were a key element of the British Army in the American Revolution. The 84th Regiment was clothed, armed and accoutred the same as the Black Watch, with Lieutenant Colonel Allan Maclean commanding the first battalion and Major General John Small of Strathardle commanding the second. The two Battalions operated independently of each other and saw little action together.
 Passage 2:By the mid-1970s, Arafat and his Fatah movement found themselves in a tenuous position. Arafat increasingly called for diplomacy, perhaps best symbolized by his Ten Point Program and his support for a UN Security Council resolution proposed in 1976 calling for a two-state settlement on the pre-1967 borders. But the Rejectionist Front denounced the calls for diplomacy, and a diplomatic solution was vetoed by the United States. In 1975, the increasing tensions between Palestinian militants and Christian militias exploded into the Lebanese Civil War, involving all factions. On 20 January 1976, the PLO took part in the Damour massacre in retaliation to the Karantina massacre. The PLO and Lebanese National Movement attacked the Christian town of Damour, killing 684 civilians and forcing the remainder of the town's population to flee. In 1976 Syria joined the war by invading Lebanon, beginning the 29‑year Syrian occupation of Lebanon, and in 1978 Israel invaded South Lebanon in response to the Coastal Road Massacre, executed by Palestinian militants based in Lebanon.
 Passage 3:Cartwright served as the president of the Philosophy of Science Association (2009–10), as vice-president (2007–8) and president (2008–9) of the Pacific Division of the American Philosophical Association, and was elected to be President of the Division for Logic, Methodology and Philosophy of Science and Technology from 2020 to 2023. She is Professor Emeritus at the London School of Economics. She is also Fellow of the British Academy, a member of the American Academy of Arts and Sciences, a member of the German Academy of Sciences Leopoldina, and a Fellow of the Academy of Social Sciences.

Question: In what country is the publication based that Patrick French writes for? Passage 1:The original train track through Irwindale were built by the Los Angeles and San Gabriel Valley Railroad. The Gold line uses the old right of way of the Los Angeles and San Gabriel Valley Railroad who built the first train tracks through Irwindale in 1887. The Los Angeles and San Gabriel Valley Railroad was founded in 1883, by James F. Crank with the goal of bringing a rail line to San Gabriel Valley from downtown Los Angeles. Los Angeles and San Gabriel Valley Railroad was sold on May 20, 1887 into the California Central Railway. In 1889 the rail line was consolidated into Southern California Railway Company. On Jan. 17, 1906 Southern California Railway was sold to the Atchison, Topeka and Santa Fe Railway and called the Pasadena Subdivision. Amtrak-Santa Fe ran the Southwest Chief and Desert Wind over this line through Irwindale, but relocated the Desert Wind to the Fullerton Line in 1986. The Santa Fe line served the San Gabriel Valley until 1994, when the 1994 Northridge earthquake weakened the bridge in Arcadia and the track was closed till the Gold line was built. The rail line crosses the San Gabriel River on a long girder bridge, then passes through the Santa Fe Dam Recreation Area (how it received its name). The rail line intersected the north end of the former SP Azusa Industrial Track at Irwindale (MP 118.2). Irwindale had a 6,165 foot rail siding that passed the Miller Brewing Company's Irwindale brewery. From there the tracks continued and crossed beneath Irwindale Avenue.
 Passage 2:The Home Rule Crisis was a political and military crisis in the United Kingdom of Great Britain and Ireland that followed the introduction of the Third Home Rule Bill in the House of Commons of the United Kingdom in 1912. Ulster unionists, determined to prevent any measure of home rule for Ireland, formed a paramilitary force, the Ulster Volunteers, which threatened to resist by physical force the implementation of the Act and the authority of any Dublin Parliament by force of arms. Irish nationalists responded by setting up the Irish Volunteers "to secure the rights and liberties common to all the people of Ireland". Both sides then began importing weapons and ammunition from Germany, in the Larne gun-running and Howth gun-running incidents. HM Government's ability to face down unionist defiance was thrown into question by the "Curragh incident", when dozens of British Army officers tendered their resignation rather than secure arms against Ulster loyalist seizure, forcing a climb-down by the government. The crisis was temporarily averted by the outbreak of World War I. The Home Rule Bill was enacted, but its implementation was suspended for the duration of the war.
 Passage 3:Jasanoff's 2017 book, The Dawn Watch: Joseph Conrad in a Global World, published by Penguin Press and in the UK by William Collins centers on the life and times of novelist Joseph Conrad. The Times lauded the book as the "Conrad for our time," and The Spectator called her an "enviably gifted writer...her historian's eye can untie knots that might baffle the pure critic," noting that she "steers us securely and stylishly through those latitudes where Conrad witnessed the future scupper the past." In the judgment of the Financial Times: "This is an unobtrusively skilful, subtle, clear-eyed book, beautifully narrated," while the Literary Review observes: "Written with a novelist's flair for vivid detail and a scholar's attention to texts, The Dawn Watch is by any standard a major contribution to our understanding of Conrad and his time." Reviewing the book in The Guardian, Patrick French began: "The Dawn Watch will win prizes, and if it doesn't, there is something wrong with the prizes." In The Hindu, Sudipta Datta wrote that Jasanoff's approach to Conrad makes for a "remarkable retelling of Joseph Conrad's life and work and its resonance with the present dysfunctional world." In The Guardian, William Dalrymple named the book to his list of best holiday reads of 2017. According to the Wall Street Journal's reviewer, "'The Dawn Watch' is the most vivid and suggestive biography of Conrad ever written." In The New York Times, Ngugi wa Thiong'O applauded the book as "masterful." Thiong'O wrote that Jasanoff succeeded where "An Image of Africa: Racism in Joseph Conrad's Heart of Darkness," Chinua Achebe's classic Conrad essay, had failed, specifically in bringing into clear relief "Conrad's ability to capture the hypocrisy of the 'civilizing mission' and the material interests that drove capitalist empires, crushing the human spirit." "'The Dawn Watch,' Thiong'O wrote, "will become a creative companion to all students of his work. It has made me want to re-establish connections with the Conrad whose written sentences once inspired in me the same joy as a musical phrase."
