[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 Nordenskjöld's party off at Snow Hill Island, a small island off the coast of the Antarctic Peninsula. Nordenskiöld overwintered at Snow Hill Island, while Antarctic returned to the Falklands. The following summer Larsen brought her south, intending to retrieve the Nordenskiöld 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 Nordenskjöld 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 Julián Irízar), 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 Nordenskjöld lasting fame at home, but its huge cost left him greatly in debt.

[EX Q]: Question: On what date did Morsi take office? Passage:Following the Egyptian revolution of 2011 as part of the regional Arab Spring protests, Mubarak was ousted and the following year Mohamed Morsi who is backed by the Muslim Brotherhood won Egypt's first democractic elections. In 2013 Morsi was removed from power in a coup led by Abdel Fattah el-Sisi. Sisi has called for religious tolerance and has cracked down and banned the Muslim Brotherhood. He has closed thousands of mosques and has banned 'burkinis' on some beaches. A The Economist report in 2017 stated that Egyptians were turning more secular again, with supporters of sharia law dropping by more than half since 2011, people praying less than before, and gender equality now being widely accepted. The government has also acted to preserve its Jewish heritage through the restoration of the abandoned Eliyahu Hanavi Synagogue in Alexandria in 2017.

[EX Q]: Question: Of the two armed forces, which one had more soldiers? Passage:The conflict emerged from the First Indochina War against the communist-led Viet Minh. Most of the funding for the French war effort was provided by the U.S. After the French quit Indochina in 1954, the US assumed financial and military support for the South Vietnamese state. The Việt Cộng, also known as or NLF (the National Liberation Front), a South Vietnamese common front under the direction of North Vietnam, initiated a guerrilla war in the south. North Vietnam had also invaded Laos in the mid-1950s in support of insurgents, establishing the Ho Chi Minh Trail to supply and reinforce the Việt Cộng. U.S. involvement escalated under President John F. Kennedy through the MAAG program from just under a thousand military advisors in 1959 to 16,000 in 1963. By 1963, the North Vietnamese had sent 40,000 soldiers to fight in South Vietnam. North Vietnam was heavily backed by the USSR and the People's Republic of China. China also sent hundreds of PLA servicemen to North Vietnam to serve in air-defense and support roles.
