Given the task definition, example input & output, solve the new input case.
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 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?
Output: span
The answer "Chandernagore" is a word from the passage. So, the answer type is "span".

New input case for you: Passage: Precise measurements of atmospheric Absorption (electromagnetic radiation) were not made until 1888 and 1904. The temperature Stefan obtained was a median value of previous ones, 1950 C and the absolute thermodynamic one 2200 K. As 2.574 43.5, it follows from the law that the temperature of the Sun is 2.57 times greater than the temperature of the lamella, so Stefan got a value of 5430 C or 5700 K (the modern value is 5778 K). This was the first sensible value for the temperature of the Sun. Before this, values ranging from as low as 1800 C to as high as 13,000,000 C were claimed. The lower value of 1800 C was determined by Claude Pouillet (17901868) in 1838 using the DulongPetit law. Pouillet also took just half the value of the Suns correct energy flux.
Question: What year was the lowest estimate for the sun's temperature proposed?
Output:
date
