instruction:
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.
question:
Passage: On 4 November 1309, Pope Clement admitted what had long been suspected, that the Hospitaller expedition would not go to the Holy Land. It was merely a preparatory campaign to help defend Cyprus and enforce the prohibition on Catholics trading with Muslims. The official expedition was ready to sail from the Italian port of Brindisi in January 1310, but was delayed until spring by bad weather. It was under the direct command of the grand master, Foulques de Villaret, who was accompanied by a papal legate, Pierre de Pleine-Chassagne. The force contained 26 galleys , two or three hundred knights and about three thousand foot soldiers. When the fleet sailed it was still unknown where Villaret planned to take it. Rather than go to the Holy Land, it sailed for the Byzantine island of Rhodes. It was in Greek waters on 13 May, when Villaret sent a message of peace to Venice. The crusader army participated in the final conquest of the city of Rhodes in August. Although no expedition to the Holy Land came out of the preaching of 1308-9, Rhodes was a strategically important base for future campaigns and the Hospitallers made it their headquarters in 1311.
answer:
How many years did these events take?


question:
Passage: Crimean Khan Haji Giray, learning of the defeat of the Budjak Tatars gathered 10,000-12,000 men and went against Kunitsky. At the end of December Kunitsky with 10,000-12,000 Cossacks and Moldavians left Budjak and began to cross the Prut River near the village of Tobak, not far from the town of Reni, Ukraine. Here on 30 December they were suddenly attacked by Tatar cavalry under Khan Haji Giray. Kunitsky built a fortified camp and successfully repelled the Tatar attacks. On the night of 3 to 4 January 1684 the Moldavian allies betrayed the Cossacks and left the Cossack camp. In this situation Kunitsky with the Cossack cavalry  broke through the enemy ring and crossed the Prut. The Cossack infantry  under Andrey Mogila also broke out and crossed the Prut near Boyanova, but suffered heavy losses. By 10 January only five thousand Cossacks reached Jassy.
answer:
How many days after the Cossacks and Moldavians were attacked by Tatar calalry under Khan Haji Giray did the Moldavian allies betray the Cossacks?


question:
Passage: By 1735, misrule and extortion proved too much and the local people rose to fight. Some of them were desperate enough as to kill their wives and children before joining the rebellion, thus burning all bridges behind them. The uprising started in Taigong, then covering the area of Liping and Duyun. Local Qing administration, unable to cope with the rebels, suggested making a kind of agreement with them, but the Qianlong Emperor recalled the previous commanders and appointed Zhang Guangsi, an experienced officer under Ortai, to quell the rebellion. The uprising was bloodily suppressed, the last rebels doggedly fighting at Niupidajing. Altogether Qing armies destroyed approximately 1200 Miao forts and killed over 18,000 warriors. The campaign lasted from February to November 1736. Zhang, meanwhile appointed Governor-General of Guizhou, started to build roads, strengthening the garrisons and opening the mines, to enhance both imperial control and the economy of the region. The suppression of the revolt granted the area half a century of peace, but the deep causes of unrest remained unchanged and the tensions grew again, until Miaos rebelled anew in 1795.
answer:

How did Zhang enhance imperial control?
