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: Another large victory gave the 49ers their first back-to-back victories of the season. Quarterback Colin Kaepernick only completed 6 of his 15 passes, with the running attack and defense at the top of their games. Frank Gore and Anthony Dixon ran for touchdowns, while cornerback Tramaine Brock picked off two Matt Schaub passes, one for a touchdown on Schaub's first pass of the game, with Tony Jerod-Eddie also picking up an interception. The 49ers improved to 3-2, just one game off the 4-1 Seattle Seahawks in the battle for NFC West, who had lost to the Indianapolis Colts.
Question: How many interceptions did the 49ers pick off?

Solution: number
