You will be given a definition of a task first, then some input of the task.
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.

Passage: On 5 October 1407, the prisoners were charged with high treason by the Ming imperial court. The Yongle Emperor asked them whether they had killed the former king and whether they had usurped the throne of the Tran royal family, but he received no answer in return. In the end, most of these prisoners were either imprisoned or executed. In June 1407, the Yongle Emperor annexed the conquered region as Jiaozhi province. Lu Yi was appointed as the military commissioner, Huang Zhong as the vice-commissioner, and Huang Fu as the provincial administrator and the surveillance commissioner. Jiaozhi province became divided into fifteen prefectures, 41 sub-prefectures, and 210 counties. The first major signs of discontent against Chinese rule would surface when Tran Ngoi revolted in September 1408. Even though he would be captured by Zhang Fu in December 1408, Tran Qui Khoang would continue the rebellion until his capture by Zhang Fu on 30 March 1414, formally ending the rebellion. Nevertheless, the region would continue to be plagued by several other uprisings during course of the Chinese domination, and the Ming occupation army was eventually evicted out of Vietnam in 1427 as the result of the Lam Son uprising. The Ming's ethnic Vietnamese collaborators included Mac Thuy whose grandfather was Mac inh Chi who was a direct ancestor of Mac ang Dung.
Output:
How many months after Tran Ngoi revolted was he captured?
