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.
One example: Passage: The outbreak of the Seven Years' War in Europe in 1756 resulted in renewed conflict between French and British forces in India. The Third Carnatic War spread beyond southern India and into Bengal where British forces captured the French settlement of Chandernagore in 1757. However, the war was decided in the south, where the British successfully defended Madras, and Sir Eyre Coote decisively defeated the French, commanded by Comte de Lally at the Battle of Wandiwash in 1760. After Wandiwash, the French capital of Pondicherry fell to the British in 1761. The war concluded with the signing of the Treaty of Paris in 1763, which returned Chandernagore and Pondichery to France, and allowed the French to have "factories" in India but forbade French traders from administering them. The French agreed to support British client governments, thus ending French ambitions of an Indian empire and making the British the dominant foreign power in India.
Question: Which french settlement did the British capture first, Chandernagore or Pondicherry?
Solution is here: span
Explanation: The answer "Chandernagore" is a word from the passage. So, the answer type is "span".

Now, solve this: Passage: Another key development in the wake of the Forty Years' War was the emergence of a unified and powerful Arakan. The western littoral between the Arakan Yoma and the Bay of Bengal remained politically fragmented even after Pagan's fall. The coast was divided between at least two power centres at Launggyet in the north and Sandoway in the south. The weakness became exposed between 1373 and 1429 when the region was first subject first to Avan and then to Peguan interference. Arakan was Pegu's vassal from 1412 at least until Razadarit's death in 1421. The restoration came in 1429 when the last king of Arakan, Saw Mon III, in exile since 1406, came back with an army provided by Sultan Jalaluddin Muhammad Shah of Bengal. Narameikhla again became king, though as a vassal of Bengal. The vassalage was brief. In 1437, Saw Mon's brother Khayi annexed Sandoway and Ramu, his overlord's territory, unifying the Arakan littoral for the first time in history. An ascendant Arakan seized Chittagong in 1459, and received tribute from the Ganges delta.
Question: What year was Khayi's brother exiled?
Solution:
date
