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: Air transportation Colombia was a pioneer in promoting airlines in an effort to overcome its geographic barriers to transportation. The Colombian Company of Air Navigation, formed in 1919, was the second commercial airline in the world. It was not until the 1940s that Colombias air transportation began growing significantly in the number of companies, passengers carried, and kilometers covered. In the early 2000s, an average of 72 percent of the passengers transported by air go to national destinations, while 28 percent travel internationally. One notable feature is that after the reforms of the beginning of the 1990s, the number of international passengers tripled by 2003. In 1993 the construction, administration, operation, and maintenance of the main airports transferred to departmental authorities and the private sector, including companies specializing in air transportation. Within this process, in 2006 the International Airport Operator (Opain), a Swiss-Colombian consortium, won the concession to manage and develop Bogota's El Dorado International Airport. El Dorado is the largest airport in Latin America in terms of cargo traffic (33rd worldwide), with 622,145 metric tons in 2013, second in terms of traffic movements (45th worldwide) and third in terms of passengers (50th among the busiest airports in the world). In addition to El Dorado, Colombia's international airports are Palo Negro in Bucaramanga, Simon Bolivar in Santa Marta, Cortissoz in Barranquilla, Rafael Nunez in Cartagena, Jose Maria Cordova in Rionegro near Medellin, Alfonso Bonilla Aragon in Cali, Alfredo Vasquez Cobo in Leticia, Matecana in Pereira, Gustavo Rojas Pinilla in San Andres, and Camilo Daza in Cucuta. In 2006 Colombia was generally reported to have a total of 984 airports, of which 103 had paved runways and 883 were unpaved. The Ministry of Transportation listed 581 airports in 2007, but it may have used a different methodology for counting them.
Question: How many more airports were unpaved than paved?
Solution:
number
