Given the task definition, example input & output, solve the new input case.
This task involves creating questions from a given passage that involve some kind of complex reasoning (including numerical reasoning).
The generated questions must require looking at more than one part of the passage to answer. Try to use a variety of reasoning types in your questions (some of the sample reasoning types are illustrated in the 'positive examples' field) and also have a variety of answer types (spans, numbers, dates). A span is a continuous phrase taken directly from the passage or question. In such questions, the answer spans are recommended to be five words. Questions with answer type "number", are expected to start with "How many". For instance, "How long did an event last?" can be phrased as "How many years did an event last?". To increase diversity, try to create more questions for which the answer will be multiple spans. Please create questions that require AT LEAST 2 arithmetic operations as illustrated in the 'positive examples' field. You are encouraged to try DIFFERENT COMBINATIONS of operations and not just limit to the combinations shown in those examples. The more challenging questions you create, the better it is.
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.
Output: Which french settlement did the British capture first, Chandernagore or Pondicherry?
This is a good question since it involves a comparison around a particular event, "British capturing the French settlement", which requires looking at more than a single sentence.

New input case for you: Passage: The Yuan emperor Ayurbarwarda maintained friendly relations with Oljaitu, ruler of the Ilkhanate. As for the relations with the Chagatai Khanate, the Yuan forces had, in fact, already for a long time been entrenched in the east. This was originally meant to keep Chapar in submission, but since the latter's defeat in 1310, the garrisons were perceived as a threat to the Chaghadaid state. In order to solve the shortages of pasture grounds, Esen Buqa I, ruler of the Chagatai Khanate sent envoys in an attempt to negotiate with the border garrison commander Tughaji Jinsank in order to convince them to adjust their position in 1312. The negotiations, however, did not go well, and strained relations between the two. Esen Buqa sent tributes to Ayurbarwada in 1312 and 1313, but the Yuan court's attempts to restrict trade between the two states kept tensions high. Ayurbarwada's emissary, Abishqa, to the Ilkhanate while travelling through Central Asia, revealed to a Chaghadayid commander that an alliance between the Yuan and the Ilkhanate had been created, and the allies forces were mobilizing to attack the khanate. Esen Buqa ordered Abishqa to be executed and decided to attack the Yuan because of these events, thus breaking the peace that his father Duwa had brokered with China in 1304. At the same time, Muslim Ozbeg Khan mounted the throne of the Golden Horde in 1312. He proscribed Buddhism and Shamanism among the Mongols in Russia, reversing the spread of the Yuan culture. Yuan envoys seems to have backed Toqta's son, a rival candidate, against Ozbeg. Esen Buqa attempted to gain an alliance of Ozbeg Khan against the Yuan and the Ilkhanate, but without success.
Output:
For how many years did the peace between the Chagatai Khanate and the Yuan last?
