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: The 800th anniversary of the original charter occurred on 15 June 2015, and organisations and institutions planned celebratory events. The British Library brought together the four existing copies of the 1215 manuscript in February 2015 for a special exhibition. British artist Cornelia Parker was commissioned to create a new artwork, Magna Carta , which was shown at the British Library between May and July 2015. The artwork is a copy of an earlier version of this Wikipedia page , hand-embroidered by over 200 people. On 15 June 2015, a commemoration ceremony was conducted in Runnymede at the National Trust park, attended by British and American dignitaries. The copy held by Lincoln Cathedral was exhibited in the Library of Congress in Washington, D.C., from November 2014 until January 2015. A new visitor centre at Lincoln Castle was opened for the anniversary. The Royal Mint released two commemorative two-pound coins. In 2014, Bury St Edmunds in Suffolk celebrated the 800th anniversary of the barons' Charter of Liberties, said to have been secretly agreed there in November 1214.
