TASK DEFINITION: This task involves annotating the answer type to a given question that involve some kind of complex reasoning (including numerical reasoning). Note that the questions require looking at more than one part of the passage to answer. There are 3 possible answer types (i) spans, (ii) numbers and (iii) dates. If the answer can be found in the passage, label it as "span". If the answer is a number, label as "number". Similarly, label "date" if you think the answer to the given question is a date.
PROBLEM: Passage: The uprising greatly reduced the Tver Principality's power in the northeastern remains of Kievan Rus'. In 1328, Öz Beg granted Ivan Kalita the duchies of Novgorod and Kostroma. Alexander Vasilyevich, the prince of Suzdal, received Vladimir and a region encompassing present day Nizhny Novgorod and Gorodets. By granting the more prestigious Vladimir to the weaker of the two princes, Öz Beg maintained adherence to the principle of "divide and rule," reasoning that Moscow's jealousy of Suzdal's lands would prevent them from allying to fight against the Golden Horde. Alexander moved to Sweden after his time in Lithuania, and then back to Pskov after the city's excommunication was lifted, under the patronage of Gediminas, Grand Duke of Lithuania. In 1335, he gained forgiveness from Öz Beg and was allowed to return to his former position in Tver, however by then, the state had lost most of its influence, being replaced by the Grand Duchy of Muscovy. This return did not last long, as both Alexander and his son Fyodor were taken to Sarai and quartered in 1339. Following the execution of Alexander Vasilievich in 1331, Ivan received the duchy of Vladimir and became the sole ruler of northeastern Russia. Favor from the khan of the Golden Horde allowed Moscow to gain power rapidly at the expense of Tver, with Tver eventually losing all influence to Moscow. However, a new rivalry was formed between the princes of Suzdal-Nizhny Novgorod. The relative power of Moscow and their strong alliance with the Horde led to a period of relative peace in Russia that was not interrupted until the reign of Dmitry Donskoy, the first prince of Moscow to openly challenge the Horde. He would later defeat them at the Battle of Kulikovo in 1380.
Question: Why was Alexander Vasiliveich taken to Sarai?

SOLUTION: span

PROBLEM: Passage: The site of the current bridge is among several sites of a slave rebellion called the Stono Rebellion, one of the earliest known organized acts against slavery in the Americas.  On September 9, 1739, twenty black slaves raided a store near the bridge; in the process they killed two storekeepers and took guns and gunpowder. The bridge survived an attempt by Union forces to burn it during the American Civil War. Union troops floated burning rafts down to the Stono Bridge, hoping the wooden structure would catch fire and burn. However, their efforts were thwarted by a Lieutenant Smith, who along with members of a naval battalion, brought the rafts to shore. There have been several bridges in this location; the last variation was a two lane bridge 1,416 feet -long, which was built in 1928, and later refurbished in 1950. This swing-span drawbridge used a 156-foot -long steel-truss which left little room for even small vessels to pass beneath unless it was open.
Question: How many years passed between the bridge being built in 1928 and it being refurbished?

SOLUTION: number

PROBLEM: Passage: In 1909 Nicaraguan President José Santos Zelaya of the Liberal Party faced opposition from the Conservative Party, led by governor Juan José 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 USS Des Moines , USS Tacoma , and collier USS Hannibal  lay in the harbor at Bluefields, Nicaragua, on the Atlantic coast with USS Prairie  en route for Colón, Panama, with 700 Marines. On December 12, 1909, Albany with 280 bluejackets and the gunboat USS Yorktown  with 155, arrived at Corinto, Nicaragua, to join the gunboat USS Vicksburg  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?
