[EX Q]: Question: What country claims ownership of the island the crew sheltered on after their ship's hull was crushed? Passage:He led the 1901-1904 Swedish Antarctic Expedition, aboard the ship Antarctic. The expedition visited the Falkland Islands before the ship, commanded by seasoned Antarctic sailor Carl Anton Larsen, dropped Nordenskjold's party off at Snow Hill Island, a small island off the coast of the Antarctic Peninsula. Nordenskiold overwintered at Snow Hill Island, while Antarctic returned to the Falklands. The following summer Larsen brought her south, intending to retrieve the Nordenskiold party, but she became trapped in ice which eventually crushed her hull, forcing Larsen and his crew to overwinter in a hastily constructed shelter on Paulet Island. Larsen and Nordenskjold finally rendezvoused at their fall-back rescue hut at Hope Bay in late 1903, where they were picked up by the Argentine Navy corvette ARA Uruguay (commanded by Julian Irizar), which had been dispatched when Antarctic had failed to make her appointed return to South America the previous year. Despite its end and the great hardships endured, the expedition was considered a scientific success, with the parties having explored much of the eastern coast of Graham Land, including Cape Longing, James Ross Island, the Joinville Island group, and the Palmer Archipelago. The expedition, which also recovered valuable geological samples and samples of marine animals, earned Nordenskjold lasting fame at home, but its huge cost left him greatly in debt.

[EX Q]: Question: What was the population of Norwood the year that Ken Livingstone got elected to represent it? Passage:Born in Lambeth, South London, to a working-class family, Livingstone joined Labour in 1968 and was elected to represent Norwood at the GLC in 1973, Hackney North and Stoke Newington in 1977, and Paddington in 1981. That year, Labour representatives on the GLC elected him as the council's leader. Attempting to reduce London Underground fares, his plans were challenged in court and declared unlawful; more successful were his schemes to benefit women and underprivileged minorities, despite stiff opposition. The mainstream media gave him the moniker "Red Ken" in reference to his socialist beliefs and heavily criticised him for supporting controversial issues like republicanism, LGBT rights, and a United Ireland. Livingstone was a vocal opponent of the Conservative Party government of Prime Minister Margaret Thatcher, which in 1986 abolished the GLC. Elected as MP for Brent East in 1987, he became closely associated with anti-racist campaigns. He unsuccessfully stood for Labour Party leader on a leftist platform in 1992 and 1994, in the latter losing to Tony Blair. Livingstone became a vocal critic of Blair's New Labour project that pushed the party closer to the centre and won the 1997 general election.

[EX Q]: Question: How long did the general who captured Roussel rule as the Byzantine Emperor? Passage:He was present at the Battle of Manzikert in 1071, where he refused to join the fray; the battle proved to be a disastrous defeat for the Byzantines. Despite this treachery, he was kept in imperial service, where good generals were needed, and was sent into Asia Minor again with a force of 3,000 Franco-Norman heavy cavalry. There Roussel conquered some territory in Galatia and declared it an independent state in 1073, with himself as prince, following the example set by his fellow Normans in the Mezzogiorno. His capital was Ankara, now the capital of Turkey. He defeated the Caesar John Ducas and sacked Chrysopolis, near Constantinople. He even supported a usurper candidate, but by formally ceding lands that the Seljuk Turks had actually conquered, the emperor Michael VII persuaded the Seljuk warlord Tutush I to remove Roussel. However both Ducas and Roussel were defeated and captured by Turkish forces, fortunately for Roussel his wife was able to pay the ransom demanded by the Turks allowing Roussel to return to Amasea, where the population so loved him that he made himself undisputed governor. He was given up by the people through a ploy of Alexius Comnenus (1074), then a general, later an emperor.
