Question: Did Louis XIV's cousin have any siblings? Passage:After Louis XIV's marriage to Maria Theresa of Spain on 9 June 1660, Queen Anne turned her attention to the marriage of Philippe. He had previously been encouraged to court his older cousin the Duchess of Montpensier, eldest daughter of Gaston and his first wife Marie de Bourbon. Known as Mademoiselle at this time, she had an immense private fortune and had previously rejected suitors such as Charles II of England. Born in 1627, she was the sole heiress of her mother who died in childbirth. Mademoiselle declined the union, complaining that Philippe always stayed near his mother as if he was "like a child". Mademoiselle instead remained unmarried. Philippe would marry instead another first cousin, Princess Henrietta of England, youngest child of King Charles I of England and his wife Queen Henrietta Maria, who was Philippe's aunt and had taken refuge at the court of France after the birth of Princess Henrietta in 1644. They lived at the Palais Royal and at the Palais du Louvre. In 1660, after the restoration of the House of Stuart to the throne of England under her brother Charles II, Princess Henrietta returned to England to visit her sister, the Princess of Orange, who later caught smallpox and died. The French court officially asked for Henrietta's hand on behalf of Philippe on 22 November 1660 while she was in England. The couple signed their marriage contract at the Palais Royal on 30 March 1661. The ceremony took place the next day in the same building in front of select members of the court. The dowry promised was a huge 840,000 livres. Known as Henriette d'Angleterre in France, and Minette to her intimates, she was known officially as Madame and was ever popular with the court. Court gossip later said that the king was the father of Henrietta's first child. Henrietta's very open flirting is said to have caused a jealous Philippe to retaliate by beginning to flaunt his sexuality openly in a less than accepting era.

She was the second of the seven-boat Project 667BDRM Delfin class, which was developed at the Rubin Design Bureau in September 1975. A ballistic missile submarine, she was designed primarily to carry up to 16 R-29RM Shtil (NATO designation: SS-N-23 Skiff) SLBM for use against military and industrial facilities in the case of a nuclear war.

Question: Which of the set of islands the expedition visited has a lower latitude? 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.
