Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following 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: span
Reason: The answer "Chandernagore" is a word from the passage. So, the answer type is "span".

Now, solve this instance: Passage: The 1936 Summer Olympics in Berlin were the first Games to be broadcast on television, though only to local audiences. The 1956 Winter Olympics were the first internationally televised Olympic Games, and the 1960 Winter Olympics had their broadcasting rights sold for the first time to specialised television broadcasting networksCBS paid US$394,000 for the American rights, and the European Broadcasting Union (EBU) allocated US$660,000. In the following decades the Olympics became one of the ideological fronts of the Cold War. Superpowers jockeyed for political supremacy, and the IOC wanted to take advantage of this heightened interest via the broadcast medium. The sale of broadcast rights enabled the IOC to increase the exposure of the Olympic Games, thereby generating more interest, which in turn created more appeal to advertisers time on television. This cycle allowed the IOC to charge ever-increasing fees for those rights. For example, CBS paid US$375 million for the American broadcast rights of the 1998 Winter Olympics, while NBC spent US$3.5 billion for the American rights of all the Olympic Games from 2000 to 2012. In 2011, NBC agreed to a $4.38 billion contract with the International Olympic Committee to broadcast the Olympics through the 2020 Summer Olympics, the most expensive television rights deal in Olympic history. NBC then agreed to a $7.75 billion contract extension on May 7, 2014, to air the Olympics through the 2032 games. NBC also acquired the American television rights to the Youth Olympic Games, beginning in 2014 Summer Youth Olympics, and the Paralympic Games for the 2014 Winter Paralympics and 2016 Summer Paralympics editions. NBC is one of the major sources of revenue for the IOC.
