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.

Example Input: Passage: Until 1998, Shearer was paid $30,000 per episode. During a pay dispute in 1998, Fox threatened to replace the six main voice actors with new actors, going as far as preparing for casting of new voices. The dispute, however, was resolved and Shearer received $125,000 per episode until 2004, when the voice actors demanded that they be paid $360,000 an episode. The dispute was resolved a month later, and Shearers pay rose to $250,000 per episode. After salary re-negotiations in 2008, the voice actors received $400,000 per episode. Three years later, with Fox threatening to cancel the series unless production costs were cut, Shearer and the other cast members accepted a 30 percent pay cut, down to just over $300,000 per episode. On May 13, 2015, Shearer announced he was leaving the show. After the other voice actors signed a contract for the same pay, Shearer refused, stating it was not enough. Al Jean made a statement from the producers saying "the show must go on," but did not elaborate on what might happen to the characters Shearer voiced. On July 7, 2015, Shearer agreed to continue with the show, on the same terms as the other voice actors.
Question: In what year did Fox threaten to cancel the series unless production costs were cut?

Example Input: Passage: The February Revolution had toppled Tsar Nicolas II of Russia, and replaced his government with the Russian Provisional Government. However, the provisional government was weak and riven by internal dissension. It continued to wage World War I, which became increasingly unpopular. A nationwide crisis developed in Russia, affecting social, economic, and political relations. Disorder in industry and transport had intensified, and difficulties in obtaining provisions had increased. Gross industrial production in 1917 had decreased by over 36% from what it had been in 1914. In the autumn, as much as 50% of all enterprises were closed down in the Urals, the Donbas, and other industrial centers, leading to mass unemployment. At the same time, the cost of living increased sharply. Real wages fell about 50% from what they had been in 1913. Russia's national debt in October 1917 had risen to 50 billion rubles. Of this, debts to foreign governments constituted more than 11 billion rubles. The country faced the threat of financial bankruptcy.
Question: When did the February Revolution occur?

Example Input: Passage: Carbon Countys live birth rate was 646 births in 1990. Carbon County live birth rate in 2000 declined to 566 births, while in 2011 it rose to 586 babies.

Urban counties have also experienced a decline in the number of school aged children. From 2000-2010 urban Pennsylvania counties had a 3 percent decline in the number of residents under 18 years old. In 2010, there were 2.07 million residents, or 22 percent of the urban population, who were under age 18.
