question:
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.

question:
Question: In what city did Henri perform Edmond Audran's Olivetter with Florence St. John's Opera Company? Passage:Henri first appeared on stage in 1879 at the age of 15 with Florence St. John's Opera Company, performing in Jacques Offenbach's Madame Favart at the Strand Theatre and Edmond Audran's Olivette at the Avenue Theatre, both in 1880, in the latter of which she played a small role. She appeared in other operettas with St. John but left in 1881 to help Lytton begin his acting career. They joined the company at Philharmonic Theatre, Islington in several plays, including The Obstinate Bretons and The Shaughraun by Dion Boucicault, and then, with Kate Santley, played at the Royalty Theatre. There they appeared in Ixion, or the Man at the Wheel by F. C. Burnand, but the theatre closed soon afterwards. Henri rejoined St. John's company, playing in Bucalossi's Les Manteaux Noirs at the Avenue Theatre in 1882. She then rejoined Santley's company at the Royalty in 1883 in The Merry Duchess, but Lytton was out of acting work all this time and was forced to take a variety of odd jobs. Henri then played in the lavish 1883 Christmas pantomime of Cinderella at the Theatre Royal, Drury Lane. Henri and Lytton married in early 1884, both aged 19, at St. Mary Abbot's Church, Kensington. Neither family attended the ceremony.
