input: Please answer the following: Given the following context:  Abaqa died in 1282 and was briefly replaced by his brother Tekuder, who had converted to Islam. Tekuder reversed Abaqa's policy of seeking an alliance with the Franks, offering instead an alliance to the Mamluk Sultan Qalawun, who continued his own advance, capturing the Hospitaller fortress of Margat in 1285, Lattakia in 1287, and the County of Tripoli in 1289. However, Tekuder's pro-Muslim stance was not popular, and in 1284, Abaqa's Buddhist son Arghun, with the support of the Great Khan Kublai, led a revolt and had Tekuder executed. Arghun then revived the idea of an alliance with the West, and sent multiple envoys to Europe.The first of Arghun's embassies was led by Isa Kelemechi, a Nestorian scientist who had been head of Kublai Khan's Office of Western Astronomy. Kelemechi met with Pope Honorius IV in 1285, offering to "remove" the Saracens (Muslims) and divide "the land of Sham, namely Egypt" with the Franks. The second embassy, and probably the most famous, was that of the elderly cleric Rabban Bar Sauma, who had been visiting the Ilkhanate during a remarkable pilgrimage from China to Jerusalem.Through Bar Sauma and other later envoys, such as Buscarello de Ghizolfi, Arghun promised the European leaders that if Jerusalem were conquered, he would have himself baptized and would return Jerusalem to the Christians. Bar Sauma was greeted warmly by the European monarchs, but Western Europe was no longer as interested in the Crusades, and the mission to form an alliance was ultimately fruitless. England did respond by sending a representative, Geoffrey of Langley, who had been a member of Edward I's Crusade 20 years earlier, and was sent to the Mongol court as an ambassador in 1291.  answer the following question:  What is the name of the person whose brother was executed?

Please answer this: Given the following context:  Ten years after the end of World War II, Tom Rath is living in suburban Connecticut with his wife Betsy and three children; he's having difficulty supporting his family on his salary writing for a nonprofit organization. Tom is also dealing with flashbacks from his combat service as an Army Captain in both the European and Pacific theaters, involving men that he killed (including, by accident, his best friend), and a young Italian girl named Maria, with whom he had a brief but heartfelt affair in Italy despite his being in a relationship with Betsy at the time. Before he left Maria for the final time to go back into battle, Tom was told that she was pregnant and was going to keep the baby. He would never see her or the child again. When an expected inheritance from Tom's recently deceased grandmother turns out to have been depleted, leaving only her large and unsaleable mansion, Betsy pressures Tom to seek a higher-paying job. Acting on a tip from a fellow train commuter, Tom applies for an opening in public relations at television network UBC. Asked to write his autobiography as part of the interview process, he refuses. Hired nonetheless, he helps network president Ralph Hopkins launch a national mental health campaign. Hopkins is powerful and highly respected, but unbeknownst to his employees, his workaholic habits have caused him to be estranged from his wife and his rebellious daughter, who soon elopes with an unsuitable man.  answer the following question:  What is the first name of the person who refuses to write their autobiography as part of the interview process?

input question: Given the following context:  In selecting his crew, De Long's priority was men with Arctic experience. For his second-in-command he chose lieutenant Charles W. Chipp, who had served with him on the Little Juniata adventure. Another veteran of the Polaris rescue mission, George W. Melville, was appointed as ship's engineer. Other experienced Arctic hands were William F. C. Nindemann, a Polaris survivor, and the ice pilot William Dunbar, who had many years' experience in whalers.The appointment of the expedition's navigating officer was problematic; John W. Danenhower, a young naval officer from a well-connected Washington family, was recommended to Bennett by the former president Ulysses S. Grant. Such sponsorship won Danenhower his place, despite a history of depression that had seen him briefly incarcerated at the Government Hospital for the Insane. On Bennett's request, Danenhower accompanied De Long on the voyage from Le Havre to San Francisco, during which he confided details of his medical history. The navigator's competent performance persuaded De Long that such troubles were in the past.The ship's surgeon, James Ambler, was assigned to the expedition by the Navy's Bureau of Medicine and Surgery, only because he was next on the list of medical officers available for sea duty. Ambler deduced from Danenhower's medical records that a probable cause of the navigator's medical lapses was syphilis, but Danenhower's influential connections ensured that he kept his place on the expedition.Two others from Jeannette's voyage from Le Havre, carpenter Albert Sweetman and boatswain John Cole, were enlisted, as was the Herald's meteorologist, Jerome Collins. Dubbed "chief scientist," he was in charge of the Edison apparatus and of a rudimentary telephone system that De Long hoped to utilize. The remaining places were filled from a long list of applicants; the cook and steward were recruited by Danenhower from San Francisco's Chinatown.  answer the following question:  What is the first name of the navigator for whose medical lapses Ambler felt the probable cause was syphilis????
output answer:
John
