[Q]: Passage: At the beginning of the period the Time of Troubles disorganized the frontier defenses and led to much destruction. The Oka region was raided almost every year, but with decreasing frequency. 1633 may have been the last crossing of the Oka. We hear more frequently of raids at such places as Kursk and Voronezh, implying stronger defense in the north and a southern movement of the Russian population. The Belgorod Line of forts was begun about 1633 and seems to have had noticeable effects after about 1640. We hear of raids on Poland in 1614-21, 1624-28, 1633, 1640 and 1642.
Question: How many years since the first and last raid passed that we heard about in Poland?
[A]: number

[Q]: Passage: On 25 June 1656, Charles X Gustav signed an alliance with Brandenburg: the Treaty of Marienburg granted Greater Poland to Frederick William in return for military aid. While the Brandenburgian elector was free of Swedish vassalage in Greater Poland, he remained a Swedish vassal for the Duchy of Prussia. Brandenburgian garrisons then replaced the Swedish ones in Greater Poland, who went to reinforce Charles X Gustav's army. On 29 June however, Warsaw was stormed by John II Casimir, who had drawn up to Charles X Gustav with a force of 28,500 regulars and a noble levy of 18,000 to 20,000. Thereupon, Brandenburg actively participated in the war on the Swedish side, prompting John II Casimir Vasa to state that while his Tartars already had the Swedes for breakfast, he would now take Frederick William into custody, where neither sun nor moon would shine. Already in May 1656, Alexis of Russia had declared war on Sweden, taking advantage of Charles being bound in Poland, and Livonia, Estonia and Ingria secured only by a Livonian army of 2,200 infantry and 400 dragoons, Magnus de la Gardie's 7,000 men in Prussia, and 6,933 men dispersed in garrisons along the Eastern Baltic coast. Alexis invaded Livonia in July with 35,000 men and took Dunaburg.
Question: On what 1/12 of a year did Charles X Gustav sign an alliance with Brandenburg?
[A]: date

[Q]: Passage: In 1909 Nicaraguan President Jose Santos Zelaya of the Liberal Party faced opposition from the Conservative Party, led by governor Juan Jose Estrada of Bluefields who received support from the U.S. government. The United States had limited military presence in Nicaragua, having only one patrolling U.S. Navy ship off the coast of Bluefields, in order to protect the lives and interests of American citizens who lived there. The Conservative Party sought to overthrow Zelaya which led to Estrada's rebellion in December 1909. Two Americans, Leonard Groce and Lee Roy Cannon, were captured and indicted for allegedly joining the rebellion and the laying of mines. Zelaya ordered the execution of the two Americans, which severed U.S. relations. The forces of Chamorro and Nicaraguan General Juan Estrada, each leading conservative revolts against Zelaya's government, had captured three small towns on the border with Costa Rica and were fomenting open rebellion in the capital of Managua. U.S. Naval warships that had been waiting off Mexico and Costa Rica moved into position. The protected cruisers USSDes Moines, USSTacoma, and collier USSHannibal lay in the harbor at Bluefields, Nicaragua, on the Atlantic coast with USSPrairie en route for Colon, Panama, with 700 Marines. On December 12, 1909, Albany with 280 bluejackets and the gunboat USSYorktown with 155, arrived at Corinto, Nicaragua, to join the gunboat USSVicksburg with her crew of 155 to protect American citizens and property on the Pacific coast of Nicaragua.
Question: How many American soldiers arrived in Corinto, Nicaragua in December?
[A]:
