Question: What car did Sommer drive in the Vanderbilt Cup? Passage:Sommer was born in Mouzon, in the Ardennes departement of France, into a wealthy Sedan carpet-making family. His father, Roger Sommer, broke the Wright Brothers' record for the longest flight in 1909. It was not until 1931 that Raymond started to display daredevil tendencies of his own, entering motor races in a privateer Chrysler Imperial. The following year, he won the 24 Hours of Le Mans race, despite having to drive over 20 hours solo after his teammate, Luigi Chinetti, retired ill. During the 1930s, Sommer was to dominate the French endurance classic, winning again in 1933 driving an Alfa Romeo alongside Tazio Nuvolari. He also led every race until 1938, only to suffer a mechanical failure, once when 12 laps in the lead. Sommer traveled to Long Island, New York, to compete in the 1936 Vanderbilt Cup where he finished fourth behind the winner, Nuvolari.

Question: How old was Itagaki Taisuke when he started The Freedom and People's Rights Movement? Passage:A major proponent of representative government was Itagaki Taisuke, a powerful leader of Tosa forces who had resigned from his Council of State position over the Korean affair in 1873. Itagaki sought peaceful rather than rebellious means to gain a voice in government. Such movements were called The Freedom and People's Rights Movement. He started a movement aimed at establishing a constitutional monarchy and a national assembly. Itagaki and others wrote the Tosa Memorial in 1874 criticizing the unbridled power of the oligarchy and calling for the immediate establishment of representative government. Dissatisfied with the pace of reform after having rejoined the Council of State in 1875, Itagaki organized his followers and other democratic proponents into the nationwide Aikokusha (Society of Patriots) to push for representative government in 1878. In 1881, in an action for which he is best known, Itagaki helped found the Jiyuto (Liberal Party), which favored French political doctrines. In 1882 Okuma Shigenobu established the Rikken Kaishinto (Constitutional Progressive Party), which called for a British-style constitutional democracy. In response, government bureaucrats, local government officials, and other conservatives established the Rikken Teiseito (Imperial Rule Party), a pro-government party, in 1882. Numerous political demonstrations followed, some of them violent, resulting in further government political restrictions. The restrictions hindered the political parties and led to divisiveness within and among them. The Jiyuto, which had opposed the Kaishinto, was disbanded in 1884, and Okuma resigned as Kaishinto president.

Question: Are there any penguins on any of the islands Otto visited? 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.
