Question: How many square miles in size is the country that Russian Empress Catherine the Great laid out plans to incite revolts across? Passage 1:Following the Belgian general election held on 13 June 2010, a process of cabinet formation started in Belgium. The election produced a very fragmented political landscape, with 11 parties elected to the Chamber of Representatives, none of which won more than 20% of the seats. The Flemish-Nationalist New Flemish Alliance (N-VA), the largest party in Flanders and the country as a whole, controlled 27 of 150 seats in the lower chamber. The Francophone Socialist Party (PS), the largest in Wallonia, controlled 26 seats. Cabinet negotiations continued for a long time. On 1 June 2011, Belgium matched the record for time taken to form a new democratic government after an election, at 353 days, held until then by Cambodia in 20032004. On 11 October 2011, the final agreement for institutional reform was presented to the media. A government coalition was named on 5 December 2011 and sworn in after a total of 541 days of negotiations and formation on 6 December 2011, and 589 days without an elected government with Elio Di Rupo named Prime Minister of the Di Rupo I Government.
Passage 2:In 1979, Mann wrote a 180-page draft of Heat. He re-wrote it after making Thief in 1981 hoping to find a director to make it and mentioning it publicly in a promotional interview for his 1983 film The Keep. In the late 1980s, he offered the film to his friend, film director Walter Hill, who turned him down. Following the success of Miami Vice and Crime Story, Mann was to produce a new crime television show for NBC. He turned the script that would become Heat into a 90-minute pilot for a television series featuring the Los Angeles Police Department RobberyHomicide division, featuring Scott Plank in the role of Hanna and Alex McArthur playing the character of Neil McCauley, renamed to Patrick McLaren. The pilot was shot in only nineteen days, atypical for Mann. The script was abridged down to almost a third of its original length, omitting many subplots that made it into Heat. The network was unhappy with Plank as the lead actor, and asked Mann to recast Hanna's role. Mann declined and the show was canceled and the pilot aired on August 27, 1989 as a television film entitled L.A. Takedown. which was later released on VHS and DVD in Europe.
Passage 3:With the outbreak of the Russo-Turkish War in August 1787, Russian Empress Catherine the Great laid out her plans to incite revolts across Ottoman Greece. Proclamations calling the Greek clergy to lead a war of liberation against the Ottomans were printed in September 1787 and February 1788. In March, Admiral Samuel Greig and Major-General Ivan Zaborovsky were tasked with signing alliances and facilitating revolts among the Christian populations in Dalmatia, Albania and Greece. The Russian consulate in the Heptanese activated its network of sleeper agents who had originally been recruited before the Orlov revolt. Louitzis Sotiris and Himariot Panos Bitsilis begin recruiting soldiers in the area of Epirus, while Antonis Psaros and Lambros Katsonis built a small naval force in Italy. For the most part Russian plans did not materialize as the Baltic Fleet failed to reach the Mediterranean Sea. Without its assistance most of Russia's local allies refused to take part in the rising.
