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.

Question: 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: How many more tons of U.S. domestic marble was produced in 2005 compared to 2006?

Answer: number


Question: Passage: The Italo-Turkish or Turco-Italian War  was fought between the Kingdom of Italy and the Ottoman Empire from September 29, 1911, to October 18, 1912. As a result of this conflict, Italy captured the Ottoman Tripolitania Vilayet , of which the main sub-provinces  were Fezzan, Cyrenaica, and Tripoli itself. These territories together formed what became known as Italian Libya. During the conflict, Italian forces also occupied the Dodecanese islands in the Aegean Sea. Italy had agreed to return the Dodecanese to the Ottoman Empire in the Treaty of Ouchy in 1912  Treaty of Lausanne). However, the vagueness of the text allowed a provisional Italian administration of the islands, and Turkey eventually renounced all claims on these islands in Article 15 of the 1923 Treaty of Lausanne. Although minor, the war was a significant precursor of the First World War as it sparked nationalism in the Balkan states. Seeing how easily the Italians had defeated the weakened Ottomans, the members of the Balkan League attacked the Ottoman Empire starting the First Balkan War before the war with Italy had ended. The Italo-Turkish War saw numerous technological changes, notably the airplane. On October 23, 1911, an Italian pilot, Captain Carlo Piazza, flew over Turkish lines on the world's first aerial reconnaissance mission, and on November 1, the first ever aerial bomb was dropped by Sottotenente Giulio Gavotti, on Turkish troops in Libya, from an early model of Etrich Taube aircraft. The Turks, lacking anti-aircraft weapons, were the first to shoot down an aeroplane by rifle fire.
Question: What happened second: the end of the Turco-Italian War or the first ever aerial bomb dropping?

Answer: span


Question: Passage: The government of Portuguese India started in 1505, six years after the discovery of the sea route to India by Vasco da Gama, with the nomination of the first Viceroy Francisco de Almeida, then settled at Kochi. Until 1752, the name "India" included all Portuguese possessions in the Indian Ocean, from southern Africa to Southeast Asia, governed - either by a Viceroy or Governor - from its headquarters, established in Goa since 1510. In 1752 Portuguese Mozambique got its own government and in 1844 the Portuguese Government of India stopped administering the territory of Portuguese Macau, Solor and Portuguese Timor, seeing itself thus confined to a reduced territorial entity in Malabar: Goa, Daman, Diu, Dadra and Nagar Haveli. Portuguese control ceased in the last two enclaves in 1954, and finally ceased in the remaining three pockets in 1961, when they were occupied by the Republic of India . This ended four and a half centuries of Portuguese rule in parts—thought tiny—of India. It may be noted that during the term of the monarchy, the title of the head of the Portuguese government in India ranged from "Governor" to "Viceroy". The title of viceroy would only be assigned to members of the nobility; It was formally terminated in 1774, although it has later been given sporadically to be decisively ended after 1835), as shown below.
Question: What year was the discovery of the sea route to India by Vasco da Gama?

Answer:
