Question: Who was the Han emperor when the Xianbei killed the Xiongnu chanyu Youliu? Passage 1:In 2010, in collaboration with the actor Enrico Lo Verso and the musician Gabriele Denaro, he created the work Sensibilità Sonore, dedicated to topics such as marginalization, poverty and childhood. The following year, he produced the documentary "Il rimorso" (the remorse), a video that narrates violence against the women. The project was being projected every year during national conferences in various Italian cities and received an award for the Social Communication. The journal Fatto Quotidiano considered it as "a virtuous example that denounces the wrong". It was previewed at the Camera dei deputati della regione Lazio (Chamber of Deputies of the Region of Lazio) and introduced the conference "Lui per Lei - un ponte fra Napoli e New York" at the city Partenopea and at the municipality of Fiumincino by the iniziative of the Assesorato alle politiche sociali (Department of social policies) as well as the event "Io non ci sto più" (I am non there anymore) dedicated to the memory Eligia Ardita, a victim of a femicide act. 2013 he directed the documentary "Streghe a Pachino: Un caso giornalistico irrisolto" (Witches at Pachino: An unsolved journalistic case), recovering after 50 years, a mysterious fact initially narrated by Beppe Ferrara in 1963 that burst a war between the media, the politics and the omertà. The same year he films three special documentaries about Mario Sesti, Sergio Donati and the musician Mauro Di Domenico. He carried out interviews with personalities from the show business, created web projects, such as the ObamaStay, a project that promotes and supports the election of the American president, which received the appreciation from the Woman for Obama and from the Electionpaper, concerning the Italian elections reported by the press agencies Agi and RAI. wrote for the Sindacato Nazionale di Critica (National Syndicate of Italian Film Critics).

From 2014 he is devoted actively for the promotion of the Patrimonio Verghiano, redeveloping the historical Cunziria, the original film location of the famous Cavalleria Rusticana, directed by Franco Zeffirelli and inspiration scenery of the homonymous novel of the writer Giovanni Verga. Muscoso eventually turned the ancient village into a stage denominating it Teatro Cunziria".
 Passage 2:The Xianbei (; ) were an ancient nomadic people that once resided in the eastern Eurasian steppes in what is today Mongolia, Inner Mongolia, and Northeastern China. They originated from the Donghu people who splintered into the Wuhuan and Xianbei when they were defeated by the Xiongnu at the end of the 3rd century BC. The Xianbei were largely subordinate to larger nomadic powers and the Han dynasty until they gained prominence in 87 AD by killing the Xiongnu chanyu Youliu. However unlike the Xiongnu, the Xianbei political structure lacked the organization to pose a concerted challenge to the Chinese for most of their time as a nomadic people. After suffering several defeats by the end of the Three Kingdoms period, the Xianbei migrated south and settled in close proximity to Chinese society and submitted as vassals, being granted the titles of Dukes. As the Xianbei Murong, Tuoba and Duan tribes were one of the Five Barbarians who were vassals of the Han Chinese Western Jin and Eastern Jin dynasties, they took part in the Uprising of the Five Barbarians as allies of the Han Chinese Eastern Jin against the other four barbarians, the Xiongnu, Jie, Di and Qiang. The Xianbei were at one point all defeated and conquered by the Di Former Qin empire before it fell apart at the Battle of Fei River at the hands of the Eastern Jin. The Xianbei later founded their own states and reunited northern China as the Northern Wei. These states opposed and promoted sinicization at one point or another but trended towards the latter and had merged with the general Chinese population by the Tang dynasty.
 Passage 3:For the rest of the 1970s, Schneider opted to star in small-budgeted, independent European productions, such as the little-seen Swiss period piece Violanta (1976, with a young Gérard Depardieu), and three consciously feministic works: the Italian production I Belong to Me (Io Sono Mia) (1978, with Stefania Sandrelli); the graphic, disturbing Memoirs of a French Whore (French title: La Dérobade) (1978, alongside Miou-Miou, and for which Schneider was nominated for Best Supporting Actress at the 1980 5th César Awards); and the lesbian Dutch drama A Woman Like Eve, directed by Nouchka van Brakel, where Schneider plays the bohemian love interest of conflicted Monique van de Ven who is married to and has children with Peter Faber.

Question: How old was the former commander of the 40th Regiment of Foot when MacDowall came to replace him? Passage 1:Becoming editor of La Lanterne in 1882, he founded two years later Le Matin. In December, 1882, he was chosen to represent the Gros-Caillou quarter in the municipal council of Paris, and was reelected in 1884. Dreyfus in this position showed a remarkable aptitude for finance. In October, 1885, he was elected deputy by the department of the Seine, and was reelected, for the Twelfth District, in 1889, in opposition to a Boulangist candidate. A radical, with wide schemes of reform, Dreyfus sat with the Extreme Left. He was appointed a member of the army commission, and also on that of espionage. He fought many duels, one with the Marquis de Morès, the anti-Semite. His publications include: Une Dictature (Le Mans, 1874); Giboyer à Saint-Pélagie (Paris, 1875); L'Evolution des Mondes et des Sociétés (Paris, 1888); Les Traités de Commerce (Tours, 1879); Le Tunnel du Simplon et les Intérêts Français (Paris, 1879); L'Angleterre, son Gouvernement, ses Institutions (Paris, 1881); La Guerre Nécessaire, Réponse d'un Français à M. de Bismarck (Paris, 1890). Dreyfus was also secretary and part founder of La Grande Encyclopédie. He was a member of the Légion d'honneur.
 Passage 2:France–United Kingdom relations are the relations between the governments of the French Republic and the United Kingdom of Great Britain and Northern Ireland (UK). The historical ties between France and the UK, and the countries preceding them, are long and complex, including conquest, wars, and alliances at various points in history. The Roman era saw both areas, except northern England and Scotland, conquered by Rome, whose fortifications exist in both countries to this day, and whose writing system introduced a common alphabet to both areas; however, the language barrier remained. The Norman conquest of England in 1066 decisively shaped English history, as well as the English language. In the medieval period, the countries were often bitter enemies, with both nations' monarchs claiming control over France. Some of the noteworthy conflicts include the Hundred Years' War and the French Revolutionary Wars which were French victories, and the Seven Years' War, Second Hundred Years’ War and Napoleonic Wars, from which Britain emerged victorious.
 Passage 3:MacDowall was appointed Lieutenant-Colonel of the 57th Regiment of Foot in 1791 and served in Flanders in 1793 and after serving as Commander-in-Chief in Ceylon from 1798 to 1804. In 1802, as a Major-General, he was appointed Colonel commandant of a Battalion of the 40th Regiment of Foot in place of Lord Hutchinson. He was appointed Commander-in-Chief of the Madras Army in 1807. He was made Colonel of the 41st Regiment of Foot in 1808. Following a period of dispute with the civil government of Madras over his exclusion from its council, and the affair of the arrest of Quartermaster-General John Munro, he resigned his commission in January 1809 and took ship for England on the East Indiaman Lady Jane Dundas. The ship was lost with all hands near the Cape of Good Hope in March 1809.

Question: How many years long was the period in which copper mineralization and pipe formation occurred? Passage 1:The copper ore deposits are those of a typical copper porphyry and associated alteration-mineralization. These altered zones include chalcopyrite, pyrite, bornite and molybdenite as hypogene minerals and chalcocite as a supergene mineral. The ore body surrounds the Braden Pipe in a continuous ring with a width of 2000 feet. The pipe is a geologic structure in the shape of an inverted cone, having a surface diameter of 4000 feet, and consisting of post-pipe breccia called the Braden Formation. The boundary of the pipe is marked by this post-pipe breccia and a pre-pipe breccia forming a belt up to 200 feet wide. "The Braden Pipe was a center of strong mineralization and structural weakness before the pipe was formed." Copper mineralization and pipe formation occurred in the Pliocene. Ore was originally mined from the Fortuna orebody at the southwest quadrant starting in 1906. Since 1922, the larger Teniente orebody has also been mined on the east side. "The best grade of ore is found in altered andesite or in andesitic flow breccia adjacent to the pre-pipe breccia."
 Passage 2:Lewis University's WLRA Radio was the first college radio station in the country to become digital. Lewis University received a $350,000 digital broadcasting project grant in the 1990s from philanthropy of The Andrew Corporation, a leading worldwide communications corporation. The studios, music archives, music scheduling system, audio storage and retrieval systems (including an AES/EBU Broadcast Electronics – Audiovault serial number 001 and 002), digital audio consoles, CD players & recorders, minidisc players and recorders, and DAT), ISDN digital phone system, ISDN and IP remote broadcast codecs, Optimod 8700 AES/EBU audio processing, AES/EBU broadcast delay, Harris Digit AES/EBU fm exciter, and transmitters were upgraded from analog to state of the art digital AES3 type I balanced and type II optical. The entire digital project was a joint venture with the Freberg Communications Corporation of Illinois, Harris Corporation of Florida, Pacific Research and Engineering of California, A-Ware Corporation (Musicmaster)  of Wisconsin, and Broadcast Electronics Corporation of Illinois. WLRA also added RDS Radio Data System to the FM transmission allowing information about the artist and song to be displayed on a radio tuned to 88.1-FM. Lewis University installed a new self standing radio tower and new digital IBOC or HD Radio ready ERI Rototiler  single bay fm antenna in 2000 adjacent to DeLaSalle Hall. WLRA increased the antenna height to HAAT and had to reduce the effective radiated power to 140 watts. WLRA moved from the basement of Fitzpatick Hall dormitory basement to new studios and broadcasting center in December 2005. The new broadcasting facility was named The Andrew Center of Electronic Media at Lewis University. The state of the art broadcasting studios and transmitters are located in DeLaSalle Hall on the Lewis University Romeoville campus. In 2005 WLRA began streaming a simulcast of the station over the Internet and in 2008 mobile media APPs for the Apple iPhone and iPod Touch. Simultaneously Apple added WLRA as one of their iTunes Radio Stations under College format. WLRA uses an AES3 Orban Opticodec audio processing/encoder for their 128kbs and 64kbs bit streams. In 2010, WLRA and Broadcast Electronics, Inc. integrated social media automation and Twitter with the newest generation of Broadcast Electronics AudioVault (FLEX) and Message Manager (TRE) RBDS data. The automation allow listeners to be notified of favorite artist being played through tagging. WLRA was the first station to have Broadcast Electronics integrate customer supplied computers, paving the way for other stations to upgrade into new generation Audiovault FLEX. In the Spring of 2012 WLRA was among the first 15 colleges selected to be part of Clear Channel Communication's iHeartRadio for both internet streaming and mobile media apps.
 Passage 3:In 1986, Mehboob met music composer Ismail Darbar who used to play the violin in film orchestras in those days. And it was Darbar who taught him the difference between poetry and film lyrics. Darbar introduced Mehboob to filmmaker Ram Gopal Varma and he began his song writing career with Varma's 1992 film Drohi whose music was composed by R. D. Burman. He then worked with A.R.Rahman on Varma's Rangeela. Rahman liked his work and introduced him to Mani Ratnam and Mehboob penned the lyrics for the Hindi (dubbed) version of Bombay. Mehboob went on to work with Rahman on films such as Thakshak, Doli Saja Ke Rakhna and Dubbed version of Dil Hi Dil Mein. He has also written the lyrics for Rahman's non-film album Maa Tujhe Salaam as well as Ratnam's Yuva.
