Input: Consider Input: Question: Was the TV series in which Colin Tapley costarred with Donald Gray still on the air during World War II? Passage:In 1933, film company Paramount Pictures wanted to re-juvenate and diversify its contract players, and launched a competition known as the "Search for Beauty"; heats took place in nations across the English-speaking world. Elred Tidbury entered in his native South Africa and was selected with Lucille du Toit, a dental nurse from Pretoria, as one of the winners. Colin Tapley, who would later appear opposite Gray in the TV series Mark Saber, was the New Zealand male winner. In total, there were 30 finalists worldwide, who were screen-tested over six weeks at the end of 1933. Of the 30, bit player contracts were awarded to 10, and Tidbury was selected as the overall male winner with a bonus of US$1,000, with which he bought a car. The overall female winner was Scottish actress Gwenllian Gill, who later followed Tidbury to Britain and became engaged to him; however, their engagement was broken off during the Second World War.

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: Who was the ruler of the State of the Teutonic Order when the Prussian Confederation rebelled? Passage:In 1454 the Prussian Confederation rebelled against the Teutonic Knights and formally asked the Polish King Casimir IV Jagiellon to incorporate Prussia into the Kingdom of Poland as a fief. This marked the beginning of the Thirteen Years' War (1454-66) between the State of the Teutonic Order and the Crown of the Kingdom of Poland. While Königsberg's three towns initially joined the rebellion, Altstadt and Löbenicht soon rejoined the Teutonic Knights and defeated Kneiphof in 1455. Grand Master Ludwig von Erlichshausen fled from the crusaders' capital at Castle Marienburg to Königsberg in 1457; the city's magistrate presented Erlichshausen with a barrel of beer out of compassion. When western Prussia was transferred to victorious Poland in the Second Peace of Thorn (1466), which ended the Thirteen Years' War, Königsberg became the new capital of the reduced monastic state, which became a fief of the Crown of the Polish Kingdom. The grand masters took over the quarters of the marshal. During the Polish-Teutonic War (1519–1521), Königsberg was unsuccessfully besieged by Polish forces led by Grand Crown Hetman Mikołaj Firlej.
