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.
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 Pondichéry 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?
Example solution: span
Example explanation: The answer "Chandernagore" is a word from the passage. So, the answer type is "span".

Problem: Passage: Trying to end a three-game skid, the Raiders flew to Qualcomm Stadium for an AFC West rematch with the San Diego Chargers.  After a scoreless first quarter, RB ReShard Lee helped the Raiders strike first with a 1-yard TD run.  The Chargers would respond with RB LaDainian Tomlinson with a 4-yard TD run.  In the third quarter, Oakland got the lead with QB Aaron Brooks completing a 2-yard TD pass to rookie WR John Madsen for the only score of the period.  However, in the fourth quarter, San Diego took control for the win, as Tomlinson threw a successful 19-yard TD pass to TE Antonio Gates on an HB Option.  Afterwards, Tomlinson would end the game with a 10-yard TD run.  With the loss, the Raiders fell to 2-9.
Question: How many yards longer was the longest touchdown pass than the shortest?

Solution: number
