[EX Q]: Question: How many years apart in age were Sweyn's sons? Passage:Gorm's son, Harald Bluetooth succeeded his father as king and married possibly three times with Gunhild, Tove and Gyrid. Harald had a son named Sweyn Forkbeard. Sweyn succeeded his father as king and married Gunhild (Świętosława of Poland). They had a son named Cnut the Great. Sweyn also ruled England in his lifetime and established the Danish Empire. When Sweyn died, his elder son Harald Svendsen became the King of Denmark, while England's former king, Ethelred, reclaimed the throne. Following Harald's death, his brother Cnut the Great became king, re-established the Danish North Sea Empire. He married Emma of Normandy with whom he had a son named Harthacnut. When Cnut died (and after the brothers of Harthacnut also had died), Harthacnut became king of Denmark and England. Upon his death, Edward the Confessor became ruler of England in 1042. Sweyn Forkbeard also had a daughter, Estrid, from whom all ruling kings and queens of Denmark after 1047 descend.

[EX Q]: Question: Which French naval officer who commanded raids from Isle de France against British merchant ships joined the French navy first? Passage:During the Napoleonic wars, Île de France became a base from which the French navy, including squadrons under Rear Admiral Linois or Commodore Jacques Hamelin, and corsairs such as Robert Surcouf, organised raids on British merchant ships. The raids (see Battle of Pulo Aura and Mauritius campaign of 1809–1811) continued until 1810 when the British sent a strong expedition to capture the island. The first British attempt, in August 1810, to attack Grand Port resulted in a French victory, one celebrated on the Arc de Triomphe in Paris. A subsequent and much larger attack launched in December of the same year from Rodrigues, which had been captured a year earlier, was successful. The British landed in large numbers in the north of the island and rapidly overpowered the French, who capitulated (see Invasion of Isle de France). In the Treaty of Paris (1814), the French ceded Île de France together with its territories including Rodrigues and Seychelles to Great Britain. The island then reverted to its former name, 'Mauritius'.

[EX Q]: Question: Who was the primary developer of the first Constitution? Passage:The Russian Soviet Republic was proclaimed on 7 November 1917 (October Revolution) as a sovereign state and the world's first constitutionally socialist state with the ideology of Communism. The first Constitution was adopted in 1918. In 1922, the Russian SFSR signed the Treaty on the Creation of the USSR officially setting up of the Union of Soviet Socialist Republics. The 1977 Soviet Constitution stated that "[a] Union Republic is a sovereign [...] state that has united [...] in the Union" and "each Union Republic shall retain the right freely to secede from the USSR". On 12 June 1990, the Congress of People's Deputies adopted the Declaration of State Sovereignty, established separation of powers (instead of Soviet form of government), established citizenship of Russia and stated that the RSFSR shall retain the right of free secession from the USSR. On 12 June 1991, Boris Yeltsin (1931–2007), supported by the Democratic Russia pro-reform movement, was elected the first and only President of the RSFSR, a post that would later become the presidency of the Russian Federation.
