Input: Consider Input: Question: When was the Aroostook War? Passage 1:The area was at the centre of the Aroostook War, a skirmish over boundary lines between the U.S.A. and what was then British North America. Originally confined to a disagreement between the State of Maine and the Colony of New Brunswick, the dispute eventually spread to involve the Government of the United States in Washington, D.C. and the British Colonial Administration in Quebec City, seat of the Governor General of Canada, who had supreme authority over all of British North America, including New Brunswick. In the wake of this international conflict, a small fortification (Fortin du Petit-Sault) was built in anticipation of a possible attack by the Americans, to complement the much larger fortification located at Fort Ingall (now Cabano) in nearby Canada (now Quebec). One of the central figures at the origin of the conflict was American-born industrialist "Colonel" John Baker, who had established sawmills and other lumber-related industries on the eastern shores of the Saint John river, an area claimed by the British that Baker wanted to be declared part of Maine as he was a fiercely nationalist American.
 Passage 2:The sculptor is unknown, although Paul MacKendrick suggests that Pythokritos of Lindos is responsible. When first discovered on the island of Samothrace (then part of the Ottoman Empire and called Semadirek) and published in 1863, it was suggested that the Victory was erected by the Macedonian general Demetrius Poliorcetes after his naval victory at Cyprus, between 295 and 289 BC. The Archaeological Museum of Samothrace continues to follow these originally established provenance and dates. Ceramic evidence discovered in recent excavations has revealed that the pedestal was set up about 200 BC, though some scholars still date it as early as 250 BC or as late as 180. Certainly, the parallels with figures and drapery from the Pergamon Altar (dated about 170 BC) seem strong. The evidence for a Rhodian commission of the statue has been questioned, however, and the closest artistic parallel to the Nike of Samothrace are figures depicted on Macedonian coins. Samothrace was an important sanctuary for the Hellenistic Macedonian kings. The most likely battle commemorated by this monument is, perhaps, the Battle of Cos in 255 BC, in which Antigonus II Gonatas of Macedonia won over the fleet of Ptolemy II of Egypt.
 Passage 3:Ari Brynjolfsson was born in Akureyri, Iceland, one of the seven children of Brynjólfur Sigtryggsson and Guðrún Rósinkarsdóttir from Hörgárdalur. He lived in Krossanes, Eyjafjörður and graduated from Menntaskólinn á Akureyri in 1948, then studied nuclear physics at the Niels Bohr Institute, University of Copenhagen, Denmark, from 1948 to 1954, gaining his PhD, with a thesis which dealt with a device he had constructed for accurately measuring magnetism in rocks. Following this he became a special research fellow of the University of Iceland from 1954 to 1955, then an Alexander von Humboldt fellow of the University of Göttingen, Germany, from 1955 to 1957. While at Göttingen he contributed important work in magnetic moments, using a self-devised instrument with which he and others provided the strongest evidence to that date for magnetic field reversals.

Input: Consider Input: 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.

Input: Consider Input: Question: Were Victoria and San Francisco in the same country? Passage 1:Educated at Edinburgh Academy and the Royal Military Academy, Woolwich, Stirling was commissioned into the Royal Artillery and saw action at the Battle of Alma, at the Battle of Balaclava and at the Battle of Inkerman as well as the Siege of Sevastopol during the Crimean War. He took part in the expedition to China during the Second Opium War in 1860 and saw action again during the Second Anglo-Afghan War in 1878. Stirling became Assistant Adjutant and Quarter Master General, Woolwich District in 1880, Commander Royal Artillery for Southern District in 1885 and Governor of the Royal Military Academy, Woolwich in 1890. In 1893 he was made a Knight Commander of the Order of the Bath in the 1893 Birthday Honours list. He went on to be Lieutenant of the Tower of London in 1900 and was promoted to full general on 5 January 1902, shortly before his retirement in August that year.
 Passage 2:American expanded its service to Asia and the Pacific. It was one of the initial US bidders in February 2010 to serve Tokyo's Haneda Airport, and was awarded rights to serve Haneda from New York JFK. American planned to begin JFK-Haneda service in January 2011, but postponed the service until February 2011 citing low booking demand, ultimately terminating its JFK-Narita service in favor of JFK-Haneda service in June 2012. American later cancelled its JFK-Haneda service in October 2013 due to the service being "quite unprofitable" due to the time constraints at Haneda Airport. American also began service between Los Angeles and Shanghai in 2011 and between Dallas/Fort Worth and Seoul in 2013, and from Dallas/Fort Worth International Airport to both Shanghai and Hong Kong in the summer of 2014, providing the first ever nonstop service between Dallas/Fort Worth and China. In October 2014, American filed a report to the DOT to launch flights from Los Angeles to Tokyo-Haneda in place of Delta's Seattle-Tacoma operating slot, sparking a war that lasted for over eight months. American was originally granted the slot as a back-up to Delta's Seattle-Haneda route if it failed to operate on a daily basis on March 28, 2015 (which would give the operating rights to American), but in June 2015, Delta announced the cancellation of its Seattle-Haneda service, claiming the daily operation was not feasible due to the route not being an economically viable one in the Seattle market due to certain regulatory and market conditions. American launched daily service from Los Angeles to Tokyo-Haneda on February 11, 2016 using their Boeing 787 aircraft. American also added daily service from Los Angeles to Sydney, Auckland and Hong Kong on their flagship Boeing 777-300ER (to Sydney and Hong Kong) and Boeing 787-8 (to Auckland) respectively (the flights to Auckland and Sydney was replaced by Boeing 787-9 aircraft in Fall 2017), returning to Australia and New Zealand for the first time since the 1990s and providing the first ever non-stop service between the Continental U.S. and Australia and New Zealand on American Airlines. American added service from Los Angeles to Beijing on November 5, 2017, and has plans for more expansion in the Asia-Pacific region in the coming years. As of November 2017, American Airlines offers service to eight destinations in Asia and Oceania from its hubs in Los Angeles, Chicago and Dallas-Fort Worth, offering a total of fifteen routes.
 Passage 3:Eli Lequime (1811–1898) was born in France and began traveling the world in 1825 at the age of fourteen. He arrived in San Francisco in 1852 for the gold rush but soon gave up. Eli returned to France and fought in the Crimean War. He returned to San Francisco by 1856 and with his new wife, Marie Louise (née Altabagoethe) he caught a boat to Victoria, British Columbia. From there, the family caught a boat to the mainland. he had two children, Bernard and Gaston. The family panned for gold at Rock Creek which is west of Osoyoos. During Eli's time at Rock Creek, his son Gaston fell into a miner's sluice box and drowned at two years of age. Eli, Marie Louise and Bernard headed for the Cariboo with the hopes of striking it rich. On their way, Marie Louise gave birth to another son, who they named Gaston. Father Pandosy met the family on the trail and convinced them to come to Okanagan Mission with him. In 1861, Eli registered a land claim northeast of the Mission. Eli built a log home and a trading post on his new property. His store soon became the social and business hub of the area. Eli and Marie Louise had two more children at the Mission, Aminade (1866) and Leon (1870). The Lequime family had over 1,300 heads of cattle and had more than two thousand acres of land. Eli lived in the Mission Valley for twenty-seven years. When he was seventy, Eli decided to move back to San Francisco. By 1888 Eli was in San Francisco with his daughter, Aminade and his niece, Dorothy. Marie Louise would join him a couple years later. In 1905, Eli Lequime's homestead was added to the K.L.O. company for $12,000.00.
