Detailed Instructions: 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.
Q: Passage: In 1723, the Kangxi Emperor's successor, the Yongzheng Emperor, sent an army of 230,000 led by Nian Gengyao to quell a Dzungar uprising in Qinghai on the Qinghai-Tibet plateau. Due to geography, the Qing army was at first unable to engage their more mobile enemy. Eventually, they met the Dzungars and defeated them. This campaign cost the treasury at least eight million silver taels. Later in Yongzheng's reign, he sent a small army of 10,000 to fight the Dzungars again. However, that army was annihilated near the Khoton Lake in 1731 and the Qing Empire once again faced the danger of losing control of Mongolia. A Khalkha ally of the Qing Empire would finally defeat the Dzungars a year later in 1732 near the Erdene Zuu Monastery in Mongolia. The Qing then made peace with the Dzungar Khanate and decided the border between them. The Han Chinese General Yue Zhongqi conquered Tibet for the Qing during the Dzungar-Qing War and attacked the Dzungars at Urumqi in Xinjiang. The Oirats were battled against by Yue Zhongqi. Yue Zhongqi lived at the Ji Xiaolan Residence. Jalangga, a Manchu Bannermen, succeeded the Han General Yue Zhongqi as commander in 1732.
A:
How many men total did the Yongzheng Emperor send to defeat the Dzungars?
