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.

Passage: By 1759, Alaungpaya had reunified all of Burma plus Manipur and Lan Na. However, his hold on Lan Na and Tenasserim coast was still nominal. The Siamese who originally were concerned about the rising power of Restored Hanthawaddy now actively supported the ethnic Mon rebels operating in the upper Tenasserim coast. In December 1759, Alaungpaya and his 40,000-strong armies invaded the Tenasserim coast. They crossed over the Tenasserim Hills, and finally reached Ayutthaya on 11 April 1760. But only five days into the siege, the Burmese king suddenly fell ill and the Burmese withdrew. The king died three weeks later, ending the war. The 1760 war was inconclusive. Although Burma had regained the upper Tenasserim coast to Tavoy, they still had to deal with Siamese supported rebellions in Lan Na  and at Tavoy . The warfare resumed in August 1765, when two Burmese armies invaded again in a pincer movement on the Siamese capital. The Burmese armies took Ayutthaya in April 1767 after a 14-months' siege. The Burmese armies sacked the city and committed atrocities that mar the Burmese-Thai relations to the present. The Burmese were forced to withdraw a few months later due to the Chinese invasions of their homeland. Burma however had annexed the lower Tenasserim coast.
Question: On what date after the siege of Ayutthaya did the Burmese kind fall ill and withdraw?
date

Passage: New Caledonia is a major source for nickel and contains roughly 10% of the worlds known nickel supply. The islands contain about 7,100,000 tonnes of nickel. With the annual production of about 107,000 tonnes in 2009, New Caledonia was the Nickel mining in New Caledonia after Russia (266,000), Indonesia (189,000), Canada (181,000) and Australia (167,000). In recent years, the economy has suffered because of depressed international demand for nickel, due to the ongoing financial crisis of 2007–2008. Only a negligible amount of the land is suitable for cultivation, and food accounts for about 20% of imports. In addition to nickel, the substantial financial support from France and tourism are keys to the health of the economy. In the 2000s, large additions were made to nickel mining capacity. The Goro, New Caledonia is expected to be one of the largest nickel producing plants on Earth. When full-scale production begins in 2013 this plant will produce an estimated 20% of the global nickel supply. However, the need to respond to environmental concerns over the countrys globally recognized ecological heritage, may increasingly need to be factored into capitalization of mining operations.
Question: How many percent of the world's nickel supply is New Caledonia not responsible for?

number
