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.

[Q]: Passage: Melgares's successor, Governor Jose Antonio Vizcarra met Navajo leaders at Paguate on 12 February 1823. His terms essentially stated that the Spanish would settle the Navajo in pueblos and energetically convert them to the Catholic religion. The Navajo were not interested in either of these proposals. They rejected the treaty and renewed the fight. Six New Mexicans were killed at Socorro in April and eight more at Sabinal in May. On 18 June 1823, Vizcarra led 1,500 troops in a 74-day expedition against the Navajo of western New Mexico. His route took him through the Chuska Mountains to the Hopi mesas in what is now Arizona, then north towards Utah, reaching Oljeto Creek in what is now San Juan County, Utah. Thirty-three Navajo were killed, of whom eight were women, and about 30 were captured. The expedition reached Canyon de Chelly in what is now eastern Arizona. In retaliation for Vizcarra's expedition, the Navajo raided Socorro again, and attacked Tome, Albuquerque and reached the outskirts of Santa Fe. The 1823 raid marked the start of a long period of raids and counter raids lasting until 1848 as New Mexicans took Navajo captive to work as slaves, and as Navajo raided to recover their people and to obtain livestock.
Question: What day did the expedition end that Vizcarra led against the Navajo of western New Mexico?
[A]: date

[Q]: Passage: Since the end of World War II, in part due to industrial size and the onset of the Cold War, the United States has often been a proponent of reduced tariff-barriers and free trade. The U.S. helped establish the General Agreement on Tariffs and Trade and later the World Trade Organization ; although it had rejected an earlier version in the 1950s . Since the 1970s, U.S. governments have negotiated managed-trade agreements, such as the North American Free Trade Agreement in the 1990s, the Dominican Republic-Central America Free Trade Agreement in 2006, and a number of bilateral agreements . In Europe, six countries formed the European Coal and Steel Community in 1951 which became the European Economic Community in 1958. Two core objectives of the EEC were the development of a common market, subsequently renamed the single market, and establishing a customs union between its member states. After expanding its membership, the EEC became the European Union in 1993. The European Union, now the world's largest single market, has concluded free trade agreements with many countries around the world.
Question: When did the countries that later formed the European Union first join?
[A]: date

[Q]: Passage: While Burma had its hands full with the Ming Chinese invasions, Siam's King Narai attempted to pick off the upper Tenasserim coast and Lan Na. He got Martaban to switch sides in March 1662, and occupied the coast. Fortunately for the Burmese, their troubles with the Ming were over. Their land and naval units recaptured Martaban and Tavoy by December 1662. They followed up on the retreating Siamese but were driven back near Kanchanaburi with heavy losses. Meanwhile, a much larger Siamese army invaded Lan Na, catching the Burmese command completely off guard. The Siamese captured Chiang Mai on 10 February 1663, and drove back Burmese forces that arrived belatedly. In November 1663, Siam launched a two-pronged invasion of the Tenasserim coast: Martaban and Moulmein in the north and Tavoy in the south. Burmese defences withstood several Siamese onslaughts until May 1664 when the invaders retreated before the rainy season arrived. Meanwhile, the Siamese garrison at Chiang Mai was holed up in a deserted city, and its troops were constantly ambushed by resistance forces whenever they ventured out of the city. In late November 1664, the Siamese evacuated Chiang Mai, and returned. This was the last major war between the two kingdoms until 1760 although they traded small raids in 1675-1676, and in 1700-1701.
Question: What happened first: Siamese captured Chiang Mai or Siam launched a two-pronged invasion?
