 Passage 2:Mušicki was stationed in Slavonski Brod at the time of the Axis invasion of Yugoslavia in April 1941 and served as the Royal Yugoslav Army commander responsible for the railroad between Belgrade and Zagreb in the rank of colonel. He demonstrated his support for the Germans by helping their forces during the invasion. Yugoslavia was quickly conquered by the Axis powers and Mušicki remained in Slavonski Brod for several months after the conquest. He attempted to join the Ustaše Militia there, but was rejected. He went to Belgrade in mid-August, where he was received by Zbor leader Dimitrije Ljotić. On 6 October, Milan Nedić, the Prime Minister of the Axis-installed puppet Government of National Salvation, appointed Mušicki to lead the Serbian Volunteer Command (, SDK). Mušicki was involved in executing Serb civilians in the town of Čačak in December 1941. He and Milan Aćimović contacted Chetnik leader Draža Mihailović on 5 December, possibly in an effort to warn him in advance of the assault the Germans had planned, codenamed Operation Mihailovic. This action prompted the Germans to question Mušicki's loyalty. He was removed from command at the end of 1941 and imprisoned by the Germans, but was later freed at Nedić's intervention.
 Passage 3:Fort Mercer was a fort on the Delaware River in New Jersey constructed by the Continental Army during the American Revolutionary War. Built by Polish engineer Thaddeus Kosciuszko under the command of George Washington, Fort Mercer was built in 1777 to block the approach to Philadelphia, Pennsylvania in concert with Fort Mifflin on the Pennsylvania side. Fort Mercer was located in an area called Red Bank, in what is now the borough of National Park, Gloucester County, New Jersey. The fort was named in honor of Brigadier General Hugh Mercer who had died earlier that year at the Battle of Princeton. The fort's site is now part of Red Bank Battlefield Historical Park, which includes a monument and museum. Several cannons attributed to British warships lost supporting the attack on the fort, and others found buried at the fort itself, are in the park.

Question: Who produced the film that Martino appeared in that was shown on BBCOne on Christmas Eve 2018? Passage 1:Despite the weakness of the Song military, they managed to slow the Mongol Empire advance for decades. The Song resistance led to the death of Möngke Khan, in 1259, at Diaoyu Fortress. The resulting withdrawal of the Mongol forces, for the customary kurultai to select a new Khan, ultimately led to the Toluid Civil War which divided the Mongol Empire. Möngke's brother, Kublai Khan, who already controlled Mongolia and China's northern territories, formerly part of the Jin Empire, declared himself Emperor of China and founded the Yuan dynasty. Kublai renewed the Mongol campaign against the Song eventually capturing the fortified cities of Fancheng, and Xiangyang during the Battle of Xiangyang in 1273, allowing his armies to advance deep into Song territory and seize its capital. On 19 March 1279, the Song chancellor Lu Xiufu committed suicide with the eight-year-old Zhao Bing after the defeat of the remaining Song forces at the Battle of Yamen bringing an end to the Song Dynasty and marking the beginning of a century of Mongolian rule over China before the establishment of the Ming Dynasty by the House of Zhu and a return to Han rule.

Question: How many inhabitants lived in the town of Hengelo at the time of the 2017 incident? Passage 1:At the time, the Turkish Minister of Family and Social Policies, Fatma Betül Sayan Kaya, was touring Germany. A visit to the Dutch town of Hengelo, close to the German border, had already been scheduled. On 11 March, the Dutch General Intelligence and Security Service received information that Kaya would try to reach Rotterdam by car. She could freely cross the border because of the Schengen Treaty. A crisis centre was established on the twenty-third floor of the Rotterdam World Port Center to coordinate police actions. Earlier, the Turkish consul in Rotterdam had indicated to the Mayor of Rotterdam, Ahmed Aboutaleb, that there were no plans for such a visit. It now proved impossible to contact the consul, which gave Aboutaleb the conviction that the consul knew of Kaya's attempt. A motorcade was intercepted but the car with the minister managed to drive away. It reached a small yard at the rear of the Turkish consulate. The Dutch police stopped Betül Sayan Kaya's entourage just metres from the Turkish consulate building. About twenty police officers, forming a special forces unit, the Dienst Speciale Interventies, masked and equipped with body armour and automatic weapons, arrested ten members of Kaya's bodyguard, on suspicion of illegally carrying firearms. A German source had indicated they had obtained a German weapons permit. No arms were discovered. Two other men were also arrested, who later proved to be the Deventer Turkish consul and the chargé d'affaires of the Turkish embassy. They in principle enjoyed diplomatic immunity. The twelve arrested men were detained for two hours and their passports were seized. A stand-off ensued for several hours in which the Turkish minister refused to leave the car. Just after midnight, a special heavy tow truck, a lift flatbed, was driven into the yard and prepared to vertically hoist the 3.5 tonne car onto the flatbed, with the minister still in it, to transport her back to Germany. The minister now left the car and demanded entrance to the consulate invoking the Vienna Convention on Diplomatic Relations. The Dutch police had orders to arrest the minister if necessary. Ultimately, she gave in to the police demands to leave the country. At the time, many news sources assumed that she had been declared persona non grata. She was, loudly protesting, taken to another car, a black armoured Mercedes, by masked Dutch police officers who accompanied her to a police station at Nijmegen near the Dutch–German border. Her passport was seized. She was not allowed to leave the station for one and a half hours, while being reunited with the ten bodyguards. She returned to Germany under German escort. Sporadic rioting occurred among the about a thousand pro-Erdoğan protesters who had come to the Turkish consulate. They were met by Dutch riot police, who arrested twelve people for violent assault and not following police instructions. Kaya's passport was returned on 12 March, 18:00, to the Turkish consul. In April 2017, Kaya's lawyer said they would file a complaint against the Dutch government at court claiming that her expulsion from the Netherlands was illegal because she was not given a written statement of the reasons for the expulsion. However, on 2 May the case was dropped when it transpired that Kaya had never been formally declared persona non grata and that from a judicial point of view she had left the Netherlands voluntarily.
 Passage 2:His grandfather was architect Alexandros Tzonis who designed many buildings in Thessaloniki during the Interwar period. Tzonis studied architecture at the National Technical University of Athens (1956 -1961). During the period of his university studies, he was instructed privately in mathematics (Pandelis Rokos) and art (Spyros Papaloukas) meeting regularly with the architect Dimitris Pikionis who was by then retired from teaching. He worked professionally as a stage designer in the theatre and art director in the cinema. (Never on Sunday, 1960 directed by Jules Dassin). In 1961 he moved to the United States as a Ford Fellow, where he pursued his studies at Yale University, briefly in the Drama School and soon after in the School of Art and Architecture under Paul Rudolph, Shadrach Woods, Robert Venturi, and Serge Chermayeff. In 1965, with sponsorship from the Twentieth Century Fund he was appointed fellow at Yale where he carried out pioneering research on Planning and Design Methodology in collaboration with Chermayeff with whom he co-authored The Shape of Community (1972). In 1968 he was invited to teach at the Graduate School of Design at Harvard University by Jerzy Soltan and Josep Lluis Sert appointed assistant professor. There he taught and did advanced research in analytical design methods in association with Walter Isard and Ovadia Salama, receiving outside advice from Anatol Rapaport and Seymour Papert. In collaboration with Ovadia Salama, introducing the newly developed method ELECTRE he worked out a new method for multi-criteria evaluation of architectural projects (1975). In collaboration with Michael Freeman, Etienne de Cointet, and his undergraduate student Robert Berwick, who became later professor of computational linguistics at MIT, he developed a method for design discourse analysis applied to the case of 17th and 18th century texts of French architectural theory, a project funded by the French Government carried out at Harvard and in France (1975).
 Passage 3:In 1870, Charles F. Dowd proposed four time zones based on the meridian through Washington, DC for North American railroads. In 1872. he revised his proposal to base it on the Greenwich meridian. Sandford Fleming, a Scottish-born engineer operating in Canada, proposed worldwide Standard Time at a meeting of the Royal Canadian Institute on February 8, 1879. Cleveland Abbe advocated standard time to better coordinate international weather observations and resultant weather forecasts, which had been coordinated using local solar time. In 1879 he recommended four time zones across the contiguous United States, based upon Greenwich Mean Time. The General Time Convention (renamed the American Railway Association in 1891), an organization of US railroads charged with coordinating schedules and operating standards, became increasingly concerned that if the US government adopted a standard time scheme it would be disadvantageous to its member railroads. William F. Allen, the Convention secretary, argued that North American railroads should adopt a five-zone standard, similar to the one in use today, to avoid government action. On October 11, 1883, the heads of the major railroads met in Chicago at the Grand Pacific Hotel and agreed to adopt Allen's proposed system.
