Part 1. Definition
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.
Part 2. 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?
Answer: span
Explanation: The answer "Chandernagore" is a word from the passage. So, the answer type is "span".
Part 3. Exercise
Passage: The month-long truce went into effect on 11 June, 1948. On the same day, the first group of 36 observers arrived via Cairo, Egypt and continued to arrive for the next three days. The first truce did not last long due to widespread violence which again erupted. As a result, the observers were withdrawn on 9 July 1948. The second truce, indefinite in length, was called by the United Nations Security Council on 15 July 1948. This declaration was to be put into effect on 18 July 1948. It was from United Nations Security Council Resolution 54 that the Mediator was instructed to supervise the observance of the truce and to establish procedures for examining alleged breaches of the truce since 11 June 1948, and authorized the Mediator to deal with breaches so far as it was within the capacity of the Mediator to do so by appropriate local action, also the Security Council Resolution 54 requested the Mediator to keep the Security Council informed concerning the operation of the truce and where necessary to take appropriate action. During the autumn of 1948, UNTSO was re-established with an increase in size to supervise the Second Truce. The first group of observers to serve in Palestine under the UN Mediator, Count Folke Bernadotte, arrived in Rhodes at 6 P.M. GMT 20 July. It included 41 Americans and about 25 Belgians and were deployed on 21 July 1948. The initial group was quickly expanded to 93 in total because of the tremendous area that had to be covered. As the number of personnel grew, the United Nations Secretariat (of Personnel) supported the creation of the United Nations Truce Supervision Organization (UNTSO), the same organization UN Military Observers are assigned to today. Initially, the command was headed by a Chief-of-Staff (a general officer from one of the participating countries) in accordance with the personal direction of the Mediator, (a civilian).
Question: When did observers arrive from Cairo?
Answer:
date
