In this task, you're given a question, along with a context passage. The passage will not have a direct answer to the question, but can include some information and a clue for the answer. Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as `a` for Yes or `b` for No.

Example Input: 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.

Example Input: Question: How many world championships have been won by the team that the Reds outscored 22-8? Passage:On the mound, the Reds relied on left-handers Don Gullett and Fred Norman to pacify the Yankee hitters in Games 1 and 2, respectively. Gullett had come back from a mid-season injury to start Game 1 but had to leave the game in the eighth inning due to a twisted ankle while Norman out-pitched ace Hunter in Game 2. Game 3 in New York pitted effective 1976 NL Rookie of the Year Pat Zachry for the Reds against newly acquired Yankee, Dock Ellis. Ellis only lasted innings, exiting in the fourth after a home run by Driessen. Game 4 was delayed a day due to rain, but the Reds were ready for the sweep. Bench's two-run home run gave the Reds a 3–1 lead. In the bottom of the eighth, a frustrated Billy Martin threw a baseball from the dugout onto the field towards home plate umpire Bill Deegan, causing his ejection from the game. In the ninth, Bench's second home run followed by back-to-back doubles by César Gerónimo and Dave Concepción made the score 7–2 and essentially blew the game open. The Cincinnati Reds outscored the New York Yankees, 22–8, and became the first NL team to repeat as World Champions since the 1921–1922 New York Giants. The Reds did not make a single offensive or defensive substitution (save pitching changes) during the entire series. Bench would claim the MVP of the series hitting .533 with two home runs and six runs batted in. His catching counterpart, Thurman Munson, had nine hits, all singles, and a .529 batting average.

Example Input: Question: What year was the wealthy businessman that Berkman tried to assassinate born? Passage:By the early 1890s he had moved away from Bavaria and, with his brother, was working in Duisburg. Together the brothers smuggled subversive anarchist literature into Germany from the Netherlands. Coming under increasing police pressure, and taking his queue from a number of other anarchist comrades in a similar predicament, early in 1892 he fled to the United States of America. On his arrival at New York he met up with the circle around Emma Goldman, Alexander Berkman, and politically like-minded comrades from Germany. Sepp Orter discovered in himself a talent for activism, turning out to have a flair for public speaking. During 1892 he was also the editor of the New York version of , published by the "Radical Workers' Association" ("Radikaler Arbeiter Bund") and the "Autonomy" group which also numbered among its members Josef Peukert. The stay in America was cut short, however. The authorities suspected that Oerter had somehow been involved in Alexander Berkman's attempt to assassinate a wealthy businessman called Henry Clay Frick. Those suspicions appear not to have been entirely unfounded. With financial assistance from Emma Goldman, Sepp Oerter returned to Germany. He travelled via London where he arrived in October, and where the editorial group publishing "Autonomy" gave him a mission to take printed material across Belgium to the German frontier in order to effect a clandestine introduction of the anarchist propaganda to Germany. Sepp Oerter was able to complete his mission with the help of his brother Fritz who had stayed behind when Sepp had escaped to America.
