Input: Consider Input: Question: When did the state government whose military aid King Suad refused to fight Britain dissolve?  Passage:Within this scheme, Dwight D. Eisenhower offered a 25 million dollar loan to the Saudi Government on 24 January 1957. In return, King Saud explained that he had refused Soviet Union military aid to fight Britain, and that Britain's policy was what urged the Arabs to seek the Soviet Union's help. He also stressed that non-aligned countries were benefiting from Soviet aid more than the American allied countries were benefiting from American aid. He considered that this aid should double if the American President wished to succeed in his endeavors. King Saud asked Dwight D. Eisenhower to exert pressure on Israel to withdraw from the occupied territories of Palestine and settle the Palestinian cause, and to convince France to reach a settlement regarding the independence of Algeria. On the other hand, he promised to inform the Arabs of the Eisenhower Doctrine and its purposes; and to inquire about the Arab reaction on the official and officious levels before making any commitments. King Saud explained to the American President that a large bulk of his country's budget was allocated to development projects and to the five-year plan and that he needed military aid before being able to play any role expected from him in fighting communism. The American government agreed to give him a 250 million dollar loan and all kinds of land, sea and air weaponry, and to train the Saudi army on how to use them.

Input: Consider Input: Question: When was the palace that Khánh jumped over the walls of built? Passage:Khánh had long been regarded as an ambitious and unscrupulous officer. Following the partition of Vietnam, Khánh, a French-trained officer who served in the French-backed Vietnamese National Army during the First Indochina War, had rallied to support Ngô Đình Diệm, who became the first president of the anti-communist South Vietnam (Republic of Vietnam). He rose to become the deputy chief of staff in the Army of the Republic of Vietnam (ARVN), but his record of political loyalty was called into question. In 1960, during an attempted coup by rebel paratroopers, Khánh jumped over the walls of the Independence Palace and joined Diệm during the siege, trying to negotiate an end to the stand-off with the rebels. Khánh parleyed with the rebels long enough for loyal forces to arrive from the outside the capital to suppress the uprising, but his critics contended that he was waiting to see which side would gain the upper hand and was not committed to Diệm. In any case, Diệm then promoted him to be the commander of II Corps. In his younger days, Khánh had joined the Việt Minh but then defected to the French colonial army after a year. Khánh claimed that he had left the Viet Minh because of its communist inclinations, but critics claimed that he was simply switching sides because the French-backed State of Vietnam offered him more opportunities for advancement.
