Example 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.
