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: Col. Edwin Sumner conducted a campaign against the Navajo in 1851. He delegated Maj. Electus Backus to build Fort Defiance in the middle of Diné bikéyah . Col Sumner entered Canyon de Chelly but Navajo harassment attacks caused him to withdraw. In 1855 a treaty was signed at Laguna Negra by Manuelito and Zarcillos Largos for the Navajo and Henry L. Dodge , Governor Merriweather, and General John Garland. Two years later a severe drought hit the Navajo and decimated their livestock and agricultural resources, causing a famine in the winter of 1857-1858. A time of social disruption ensued. Surrounding tribes gradually increased their attacks on the weakened Navajo. The Navajo demanded in 1858 that Fort Defiance stop grazing their livestock on prime Navajo land. Soldiers shot 48 cattle and 8 horses belonging to Manuelito. Navajo warriors killed a servant of the commanding officer in retaliation for the killing of their people's livestock without compensation. The United States military demanded the murderer be brought to them, or they would begin a war. The Miles Campaign was sent against them, leaving Fort Defiance on September 9.
Question: What year did a severe drought hit the Navajo?

SOLUTION: date

PROBLEM: Passage: By the end of 1594, certain League members still worked against Henry across the country, but all relied on Spain's support. In January 1595, the king declared war on Spain to show Catholics that Spain was using religion as a cover for an attack on the French state—and to show Protestants that his conversion had not made him a puppet of Spain. Also, he hoped to take the war to Spain and make territorial gain. The conflict mostly consisted of military action aimed at League members, such as the Battle of Fontaine-Française, though the Spanish launched a concerted offensive in 1595, taking Doullens, Cambrai and Le Catelet and in the spring of 1596 capturing Calais by April. Following the Spanish capture of Amiens in March 1597 the French crown laid siege until its surrender in September. With that victory Henry's concerns then turned to the situation in Brittany where he promulgated the Edict of Nantes and sent Bellièvre and Brulart de Sillery to negotiate a peace with Spain. The war was drawn to an official close after the Edict of Nantes, with the Peace of Vervins in May 1598.
Question: What religion was King Henry?

SOLUTION: span

PROBLEM: Passage: According to the United States Geological Survey, U.S. domestic marble production in 2006 was 46,400 tons valued at about $18.1 million, compared to 72,300 tons valued at $18.9 million in 2005. Crushed marble production (for aggregate and industrial uses) in 2006 was 11.8 million tons valued at $116 million, of which 6.5 million tons was finely ground calcium carbonate and the rest was construction aggregate. For comparison, 2005 crushed marble production was 7.76 million tons valued at $58.7 million, of which 4.8 million tons was finely ground calcium carbonate and the rest was construction aggregate. U.S. dimension marble demand is about 1.3 million tons. The DSAN World Demand for (finished) Marble Index has shown a growth of 12% annually for the 2000–2006 period, compared to 10.5% annually for the 2000–2005 period. The largest dimension marble application is tile.
Question: What year was U.S. domestic marble production highest?

SOLUTION:
date
