The answer to the question: What is the name of the person who would have himself baptized and would return Jerusalem to the Christians? is inside the article: 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., can you guess it ?
Ans: Arghun

The answer to the question: What three additional locations are within range of Taapaca? is inside the article: Most of the volcanoes in northern Chile are far from towns and inhabited areas and thus their activity does not create significant human hazards. Putre is constructed on pyroclastic deposits of the Taapaca, facing a threat from future eruptions. A highway (Chile Route 11 between La Paz and Arica) linking Bolivia with the Pacific Ocean is also in range on the southern flank, while the road to Visviri in Peru runs along the southwestern and western flanks. Additional areas within range of Taapaca are the towns of Socoroma and Zapahuira, as well as the Oruro Department in Bolivia. The danger is accentuated by the fact that Holocene activity has affected mainly the southwestern flank, where Putre is located. The average time between eruptions at Taapaca is about 450 years.Future activity at Taapaca could result in further sector collapses when magma is injected into the edifice and deforms it, to the point that the volcano becomes unstable. Likewise, if lava domes are extruded onto the volcano they could generate block and ash flows as well as both primary and secondary pyroclastic flows. Eruptions between April and November (when the volcano is covered by snow) might generate lahars, as could rainfall during the wet season between December and March; the latter type of lahar happens frequently on present-day Taapaca owing to the steep slopes of the volcano, although it usually results solely in road damage.The Chilean SERNAGEOMIN geological service monitors the volcano and shows a volcano hazard level for it. It also publishes a hazard map for Taapaca, which shows risk areas for lava bomb falls, pyroclastic flows and tephra fallout., can you guess it ?
Ans: Zapahuira

The answer to the question: What is the name of the ship Shackleton calculated had travelled a mere 95 miles since 19 January? is inside the article: On 21 February 1915, Endurance, still held fast, drifted to her most southerly latitude, 76° 58′S. Thereafter she began moving with the pack in a northerly direction. On 24 February, Shackleton realised that they would be held in the ice throughout the winter, and ordered ship's routine abandoned. The dogs were taken off board and housed in ice-kennels or "dogloos", and the ship's interior was converted to suitable winter quarters for the various groups of men—officers, scientists, engineers, and seamen. A wireless apparatus was rigged, but their location was too remote to receive or transmit signals.Shackleton was aware of the recent example of Wilhelm Filchner's ship, the Deutschland, which had become icebound in the same vicinity three years earlier. After Filchner's attempts to establish a land base at Vahsel Bay failed, his ship Deutschland was trapped on 6 March 1912, about 200 miles (320 km) off the coast of Coats Land. Six months later, at latitude 63° 37', the ship broke free, then sailed to South Georgia apparently none the worse for its ordeal. Shackleton thought that a similar experience might allow Endurance to make a second attempt to reach Vahsel Bay in the following Antarctic spring.In February and March, the rate of drift was very slow. At the end of March Shackleton calculated that the ship had travelled a mere 95 miles (153 km) since 19 January. However, as winter set in the speed of the drift increased, and the condition of the surrounding ice changed. On 14 April, Shackleton recorded the nearby pack "piling and rafting against the masses of ice"—if the ship was caught in this disturbance "she would be crushed like an eggshell". In May, as the sun set for the winter months, the ship was at 75° 23′S, 42° 14′W, still drifting northwards. It would be at least four months before spring brought the chance of an opening of the ice, and there was no certainty that Endurance would break free in time to attempt a return to the Vahsel Bay area. Shackleton now considered the possibility of finding an..., can you guess it ?
Ans: Endurance
