Given the task definition and input, reply with output. 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: Athanasius had returned to Albania by the summer of 1596 and stayed in Himara. A contemporary source stated that there were 10,000 fighters in red costumes in Himara. The revolt was active in July and August, with initial success, the rebels managing to control the coastal towns. The rebel force being reinforced by a small unit of Spaniards attacked the nearby Ottoman fort of Cerna. The fort was simultaneously attacked from three directions by 1,300 men, of whom only 300 were equipped with arquebuses. Initially a group of 100 Spaniards managed to capture part of the fort raising their flag, killing 80 Ottoman soldiers among whom the commander of the fort. However the Himariotes being confused about this turn of the battle withdrew from the battlefield. This gave the opportunity to the Ottomans to launch a successful counterattack. The revolt was easily suppressed after the Venetians convinced some of the chieftains not to join the rebellion, and the fact that the rebel army was undisciplined.
How many months was the revolt active for?
