Q: Question: How long had Ferdinand I been in power the year Coimbra fell? Passage:The history of the county of Portugal is traditionally dated from the reconquest of Portus Cale (Porto) by Vímara Peres in 868. He was named a count and given control of the frontier region between the Limia and Douro rivers by Alfonso III of Asturias. South of the Douro, another border county would be formed decades later when what would become the County of Coimbra was conquered from the Moors by Hermenegildo Guterres. This moved the frontier away from the southern bounds of the county of Portugal, but it was still subject to repeated campaigns from the Caliphate of Córdoba. The recapture of Coimbra by Almanzor in 987 again placed the County of Portugal on the southern frontier of the Leonese state for most of the rest of the first county's existence. The regions to its south were only again conquered in the reign of Ferdinand I of León and Castile, with Lamego falling in 1057, Viseu in 1058 and finally Coimbra in 1064.

Q: Question: On what date was the person who sent an emissary rather than attend the 1931 meeting with Luciano and three others in person born? Passage:In April 1931, Salvatore Maranzano, head of the Castellammarese clan in New York City, declared himself capo di tutti capo (boss of all bosses). Lucky Luciano, who opposed Maranzano's claim to control the Luciano crime family, decided to have Maranzano murdered. On April 21, 1931, he met in Cleveland with Frank Milano, Moe Dalitz, Meyer Lansky, Santo Trafficante Sr., and an emissary sent by Al Capone. The five agreed with Luciano's plan to kill Maranzano and establish a new federation of crime families to handle disputes. After the September 10, 1931, assassination of Maranzano, the title of capo di tutti capo was retired and "The Commission" established by the American Mafia. Milano was named a member of The Commission, alongside Joseph Bonanno, Al Capone, Tommy Gagliano, Lucky Luciano, Vincent Mangano, and Joe Profaci.

Q: Question: Who were the leaders of the group that staged a coup against the Cypriot President? Passage:Turkish Cypriot migration to Australia began in the late 1940s; they were the only Muslims acceptable under the White Australia Policy. Prior to 1940, the Australian Census recorded only three settlers from Cyprus that spoke Turkish as their primary language, although many Turkish Cypriot arrivals spoke Greek as their first language. A further 66 Turkish Cypriots arrived in Australia in the late 1940s, marking the beginning of a Turkish Cypriot immigration trend to Australia. By 1947-1956 there were 350 Turkish Cypriot settlers who were living in Australia. Between 1955-1960, the Turkish Cypriots felt vulnerable in Cyprus as they had cause for concern about the political future of the island when the Greek Cypriots attempted to overthrow the British government and unite Cyprus with Greece (known as "enosis"). After a failed attempt by the Greek Cypriots, the right-wing party, EOKA, reformed itself from 1963–1974 and launched a series of attacks. This resulted in the exodus of more Turkish Cypriots to Australia in fear for their lives. Early Turkish Cypriot immigrants to Australia found jobs working in factories, out in the fields, or building national infrastructure. Some Turkish Cypriots also became entrepreneurs and established their own businesses once they had saved enough money. By 1974, an exodus of more Turkish Cypriots to Australia occurred due to fears that the island would unite with Greece when the Greek military junta staged a coup d'état against the Cypriot President, with the help of EOKA B. Immigration to Australia has continued since as a result of an economic embargo which was launched against the Turkish Cypriots by the Greek Cypriot controlled Republic of Cyprus due to the establishment of the Turkish Republic of Northern Cyprus (TRNC) which has remained internationally unrecognised except by Turkey.
