Definition: 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.
Input: Passage: In early 1765, a 20,000-strong Burmese army stationed at Kengtung, led by Gen. Ne Myo Thihapate, left Kengtung for yet another Burmese invasion of Siam. With the main Burmese army gone, Liu used a few minor trade disputes between local Chinese and Burmese merchants as the excuse to order an invasion of Kengtung in December 1765. The invasion force, which consisted of 3,500 Green Standard troops along with Tai-Shan militias, laid siege to Kengtung but could not match battle-hardened Burmese troops at the Kengtung garrison, led by Gen. Ne Myo Sithu. The Burmese lifted the siege and pursued the invaders into Pu'er Prefecture, and defeated them there. Ne Myo Sithu left a reinforced garrison, and returned to Ava in April 1766. Governor Liu, in his embarrassment, first tried to conceal what had happened. When the emperor became suspicious, he ordered Liu's immediate recall and demotion. Instead of complying, Liu committed suicide by slicing his throat with a stationery knife, writing as blood was pouring from his neck: "There is no way to pay back the emperor's favor. I deserve death with my crime". While this kind of suicide in the face of bureaucratic failure apparently was not unusual in Qing China, it reportedly enraged the Emperor nonetheless. Sorting out the Mien was now a matter of imperial prestige. The Emperor now appointed Yang Yingju, an experienced frontier officer with long service in Xinjiang and Guangzhou.
Output:
How many more men were in the Burmese army than Green Standard troops?
