Question: How many nations comprise the organization that Albania complained to concerning Royal Navy conducting mine-clearing operations in Albanian territorial waters, Passage:The Corfu Channel Incident refers to three separate incidents involving Royal Navy ships in the Straits of Corfu which took place in 1946, and it is considered an early episode of the Cold War. During the first incident, Royal Navy ships came under fire from Albanian fortifications. The second incident involved Royal Navy ships striking mines and the third incident occurred when the Royal Navy conducted mine-clearing operations in the Corfu Channel, but in Albanian territorial waters, and Albania complained about them to the United Nations. This series of incidents led to the Corfu Channel Case, where the United Kingdom brought a case against the People's Republic of Albania to the International Court of Justice. Because of the incidents, Britain, in 1946, broke off talks with Albania aimed at establishing diplomatic relations between the two countries. Diplomatic relations were only restored in 1991.

Question: How old was the person who escaped to Africa when Cleopatra ascended to the throne? Passage:Caesar crossed the Rubicon accompanied by the XIII Legion to take power from the senate in the same way that Sulla had done in the past. Formally declared an enemy of the state, Caesar pursued the Senatorial party, now led by Pompey, who abandoned the city to raise arms in Greece. Cato was sent to Sicily to secure control of the grain supply. After securing control of Italy, Caesar sent the praetor Curio with four legions to Sicily. Cato's garrison was insufficient to withstand a force of this magnitude, he abandoned the island and went to Greece to join Pompey. After first reducing Caesar's army at the siege battle of Dyrrhachium, where Cato commanded the port, the army led by Pompey was ultimately defeated by Caesar in the Battle of Pharsalus (Cato wasn't present during the battle, Pompey had left him in command of Dyrrhachium). Cato and Metellus Scipio, however, did not concede defeat and escaped to the province of Africa with fifteen cohorts to continue resistance from Utica. Caesar pursued Cato and Metellus Scipio after installing the queen Cleopatra VII on the throne of Egypt, and in February 46 BC the outnumbered Caesarian legions defeated the army led by Metellus Scipio at the Battle of Thapsus. Acting against his usual strategy of clemency, Caesar did not accept surrender of Scipio's troops, but had them all slaughtered.

Question: In what years was William Temple governor? Passage:After the election of Abraham Lincoln and the secession of the Confederate states, Temple took a position opposing the enforced restoration of the Union, and joined the Democratic Party. After presiding over a futile "Peace Convention" in Dover in June 1861, he became the Democratic candidate for the U.S. House of Representatives in the hotly contested and controversial 1862 election. His opponent was the incumbent Republican George P. Fisher, who had served as Secretary of State when Temple was governor. Now Fisher was convinced that there were various schemes being planned to prevent a legitimate election. Accordingly, he requested that Abraham Lincoln leave the Delaware troops in the U.S. Army home until after the election, and that he send additional Federal troops to supervise the polls on election day. The Democrats were outraged and managed to narrowly elect Temple and a majority in the General Assembly, although losing the governorship. While officially a member of the U.S. House from March 4, 1863, Temple died before the December convening of the House, and consequently never actually served. He was forty-nine years old. In a subsequent special election, Republican Nathaniel B. Smithers won the seat due to a Democratic Party boycott of the election in protest of the continuing presence of Federal troops at the polling places.
