Problem: In late 1203, John attempted to relieve Château Gaillard, which although besieged by Philip was guarding the eastern flank of Normandy. John attempted a synchronised operation involving land-based and water-borne forces, considered by most historians today to have been imaginative in conception, but overly complex for forces of the period to have carried out successfully. John's relief operation was blocked by Philip's forces, and John turned back to Brittany in an attempt to draw Philip away from eastern Normandy. John successfully devastated much of Brittany, but did not deflect Philip's main thrust into the east of Normandy. Opinions vary amongst historians as to the military skill shown by John during this campaign, with most recent historians arguing that his performance was passable, although not impressive.[nb 8] John's situation began to deteriorate rapidly. The eastern border region of Normandy had been extensively cultivated by Philip and his predecessors for several years, whilst Angevin authority in the south had been undermined by Richard's giving away of various key castles some years before. His use of routier mercenaries in the central regions had rapidly eaten away his remaining support in this area too, which set the stage for a sudden collapse of Angevin power.[nb 9] John retreated back across the Channel in December, sending orders for the establishment of a fresh defensive line to the west of Chateau Gaillard. In March 1204, Gaillard fell. John's mother Eleanor died the following month. This was not just a personal blow for John, but threatened to unravel the widespread Angevin alliances across the far south of France. Philip moved south around the new defensive line and struck upwards at the heart of the Duchy, now facing little resistance. By August, Philip had taken Normandy and advanced south to occupy Anjou and Poitou as well. John's only remaining possession on the Continent was now the Duchy of Aquitaine.
What did John attempt to relieve in late 1203?
The answer is the following: Château Gaillard

Problem: Solar hot water systems use sunlight to heat water. In low geographical latitudes (below 40 degrees) from 60 to 70% of the domestic hot water use with temperatures up to 60 °C can be provided by solar heating systems. The most common types of solar water heaters are evacuated tube collectors (44%) and glazed flat plate collectors (34%) generally used for domestic hot water; and unglazed plastic collectors (21%) used mainly to heat swimming pools.
How much hot water can be produced by solar heating systems in low geographical latitudes?
The answer is the following: 60 to 70% of the domestic hot water

Problem: Gaddafi organized demonstrations and distributed posters criticizing the monarchy. In October 1961, he led a demonstration protesting Syria's secession from the United Arab Republic. During this they broke windows of a local hotel accused of serving alcohol. Catching the authorities' attention, they expelled his family from Sabha. Gaddafi moved to Misrata, there attending Misrata Secondary School. Maintaining his interest in Arab nationalist activism, he refused to join any of the banned political parties active in the city – including the Arab Nationalist Movement, the Arab Socialist Ba'ath Party, and the Muslim Brotherhood – claiming he rejected factionalism. He read voraciously on the subjects of Nasser and the French Revolution of 1789, as well as the works of Syrian political theorist Michel Aflaq and biographies of Abraham Lincoln, Sun Yat-sen, and Mustafa Kemal Atatürk.
What political idealogy did Gaddafi not believe in?
The answer is the following: factionalism

Problem: The Jesuit China missions of the 16th and 17th centuries "learned to appreciate the scientific achievements of this ancient culture and made them known in Europe. Through their correspondence European scientists first learned about the Chinese science and culture." Western academic thought on the history of Chinese technology and science was galvanized by the work of Joseph Needham and the Needham Research Institute. Among the technological accomplishments of China were, according to the British scholar Needham, early seismological detectors (Zhang Heng in the 2nd century), the water-powered celestial globe (Zhang Heng), matches, the independent invention of the decimal system, dry docks, sliding calipers, the double-action piston pump, cast iron, the blast furnace, the iron plough, the multi-tube seed drill, the wheelbarrow, the suspension bridge, the winnowing machine, the rotary fan, the parachute, natural gas as fuel, the raised-relief map, the propeller, the crossbow, and a solid fuel rocket, the multistage rocket, the horse collar, along with contributions in logic, astronomy, medicine, and other fields.
What type of fan originated in China?
The answer is the following:
rotary
