Input: Consider Input: Question: How old was the Prime Minister when he ordered an invasion that led to the Eritrea War in 1887? Passage 1:Italy's search for colonies continued until February 1886, when, by secret agreement with Britain, it annexed the port of Massawa in Eritrea on the Red Sea from the crumbling Egyptian Empire. Italian annexation of Massawa denied the Ethiopian Empire of Yohannes IV an outlet to the sea and prevented any expansion of French Somaliland. At the same time, Italy occupied territory on the south side of the horn of Africa, forming what would become Italian Somaliland. However, Italy coveted Ethiopia itself and, in 1887, Italian Prime Minister Agostino Depretis ordered an invasion, leading to the Eritrea War. This invasion was halted after the loss of five hundred Italian troops at the Battle of Dogali. Depretis's successor, Prime Minister Francesco Crispi signed the Treaty of Wuchale in 1889 with Menelik II, the new emperor. This treaty ceded Ethiopian territory around Massawa to Italy to form the colony of Italian Eritrea, and – at least, according to the Italian version of the treaty – made Ethiopia an Italian protectorate. Relations between Italy and Menelik deteriorated over the next few years until the First Italo-Ethiopian War broke out in 1895, when Crispi ordered Italian troops into the country. Vastly outnumbered and poorly equipped, the result was a decisive defeat for Italy at the hands of Ethiopian forces at the Battle of Adwa in 1896. The Ethiopians were supported by Russian advisers and equipment, as well as by a unit of Russian volunteers. The death toll was 6,889, including 4,133 Italians. The Ethiopians counted at least 4,000 dead and 10,000 wounded. Total Italian, Eritrean, and Somali deaths, including those from disease, were estimated at 9,000.

Since 2018, she has served as a trustee of the National Humanities Center in Research Triangle Park, NC. She was elected a Member of the American Philosophical Society in 2019.
 Passage 3:Arsenal had a better European record, compared to Galatasaray going into the match; they defeated Anderlecht with a 4–3 aggregate winning result, in the final of the 1969–70 Inter-Cities Fairs Cup. The London–based club reached the Cup Winners' Cup finales three times, in 1980, where they suffered a 4–5 defeat in a penalty shoot-out to Valencia, following a 0–0 stalemate; Arsenal also reached the 1994 final, winning 1–0 over Parma, and the following edition, losing 1–2 at the hands of Real Zaragoza. Their 1994 success led to them qualifying for that year's European Super Cup, where they were beaten 2–0 by Milan on aggregate in two games. This was Arsenal's first UEFA Cup (sixth in total) European final. The club were considered favorites to win the match.

Input: Consider Input: Question: What was the size of Princeton's endowment the year Beale was born? Passage 1:Un'yō  was one of the ships dispatched to Kyūshū in 1874 during the Saga Rebellion. In May 1875, she carried diplomats to Busan in Korea in an attempt by the Japanese government to open diplomatic relations with the Joseon dynasty government. After they were rebuffed in these negotiations, the Japanese government again dispatched Un'yō in September 1875 under the command of Inoue Yoshika to provoke a military response, in what was later termed the Ganghwa Island incident. This eventually led to the Treaty of Ganghwa, which opened the Korean Peninsula to Japanese trade. In 1876, Un'yō  was assigned to assist in the suppression of the Hagi Rebellion, another uprising of disaffected former samurai. Un'yō  was severely damaged when she ran aground off the coast of the Kii Peninsula, and was scrapped the following year.
 Passage 2:Beale was born in 1948 in St. Louis County, Minnesota to C. Gordon Beale, a minister of the United Church of Christ, and Marcella Beale, a nurse. He served in the United States Army as a medic in the early 1970s and was honorably discharged. Beale attended the University of California, Riverside, earning a bachelor's degree in political science in 1975, using resources provided by the G.I. Bill. Beale interned for Democrat US Senator John V. Tunney while in college, assisting in the negotiation of the Bilingual Courts Act. He later simultaneously earned a Master of Public Administration from Princeton University and a law degree from New York University. Beale was employed with a law firm consisting of three partners in Lake City, Minnesota for four years prior to his work with the EPA. During his time with this law firm, he primarily dealt with the Federal Election Commission and the Securities and Exchange Commission.
 Passage 3:Cecil's success in 2011 was partly due to his training of the Khalid Abdullah-owned Frankel. In the 2010 season Frankel won the Royal Lodge Stakes and Group One Dewhurst Stakes. The following year he continued unbeaten, winning the Greenham Stakes, the 2,000 Guineas, the St. James's Palace Stakes at Royal Ascot, the Sussex Stakes and the Queen Elizabeth II Stakes. His six length victory in the 2,000 Guineas was described as "one of the greatest displays on a British racecourse". After his win in the Sussex Stakes Cecil himself described Frankel as "the best horse I've ever seen". Timeform and the International Federation of Horseracing Authorities rated him the best horse in the world. In his four-year-old season Frankel won the Group One Lockinge Stakes at Newbury before an eleven length victory in the Queen Anne Stakes at Royal Ascot, described in one national newspaper as "possibly the best single performance by any horse, on any track, since three Arabian stallions were imported into Britain to found the thoroughbred breed in the early years of the 18th century". Timeform raised their rating to 147, making Frankel the highest rated horse in their history. He won a second Sussex Stakes, at odds of 1–20, and then stepped up in distance to win by seven lengths the Juddmonte International Stakes at York over 10 furlongs. In October 2012 Frankel won the Champion Stakes at Ascot to finish his career unbeaten. "He's the best I've ever had, the best I've ever seen", Cecil told the BBC after the race, "I'd be very surprised if there's ever been a better."

Input: Consider Input: Question: Were the two scientists who conducted survey that confirm the length of a metre both born in France? Passage 1:Tatel received his Bachelor of Arts degree from the University of Michigan and his Juris Doctor from the University of Chicago Law School. Following law school, he served as an instructor at the University of Michigan Law School and then joined Sidley Austin in Chicago. Since then, he served as founding director of the Chicago Lawyers' Committee for Civil Rights Under Law, Director of the National Lawyers' Committee for Civil Rights Under Law, and Director of the Office for Civil Rights of the United States Department of Health, Education, and Welfare during the Carter Administration. Returning to private practice in 1979, Tatel joined Hogan & Hartson, where he founded and headed the firm's education practice until his appointment to the D.C. Circuit. While on sabbatical from Hogan & Hartson, Tatel spent a year as a lecturer at Stanford Law School. He also previously served as Acting General Counsel for the Legal Services Corporation.
 Passage 2:When Bart and Milhouse visit the local video arcade at the beginning of the episode, Martin Prince is seen playing an arcade game based on the 1981 film My Dinner with Andre. Other games at the arcade include a game based on the 1984 film The Terminator. The "Springfield, Springfield" number performed by Bart and Milhouse on their night out in town is a reference to the musical number "New York, New York" from the film On the Town, starring Gene Kelly and Frank Sinatra. During a scene in which Hans Moleman and Moe fight with knives, Hans tells Moe, "You call that a knife? This is a knife!", a reference to a line from the 1986 film "Crocodile" Dundee. Ernest Borgnine introduces himself a la Troy McClure to the Junior Campers by recalling his role in From Here to Eternity, a film which modern children are unlikely to have seen. During a hallucination, Homer imagines himself singing the song "Sugar, Sugar" by The Archies while dancing with lollipops and ice cream cones. While on the raft, Homer misquotes lines from Samuel Taylor Coleridge's The Rime of the Ancient Mariner when he says "Water, water everywhere/So let's all have a drink." The scene in which Borgnine and the other rafters drift through a dark forest watched by mountain men is a reference to a scene in the 1972 film Deliverance, and the scene features the music from the film's "Dueling Banjos" scene. The unseen person or creature that attacks Borgnine at the end of the episode is implied to be Jason Voorhees from the Friday the 13th film series.
 Passage 3:Bouguer, La Condamine, Godin and their colleagues measured arcs of the Earth's curvature on the Equator from the plains near Quito to the southern city of Cuenca. These measurements enabled the first accurate determination of the shape of the Earth, eventually leading to the establishment of the international metric system of measurement. When an International Commission for Weights and Measures was convened in Paris to settle the true length of the metre, it adopted on 22 June 1799 a standard metre based on the length of the half meridian connecting the North pole with the Equator. The French Academy of Sciences had commissioned an expedition led by Jean Baptiste Joseph Delambre and Pierre Méchain, lasting from 1792 to 1799, which attempted to accurately measure the distance between a belfry in Dunkerque and Montjuïc castle in Barcelona at the longitude of Paris Panthéon. This portion of the Paris meridian was to serve as the basis for the length of the half meridian connecting the North Pole with the Equator. The metre was defined as the ten-millionth of the half meridian's length extrapolated from a Earth's flattening of 1/334 obtained from the results of the survey by Delambre and Méchain combined with those of the Peru meridian arc as established by La Condamine and his colleagues.
