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.

Ex Input:
Passage: Richard Gabriel estimated that roughly 2,400 PLO fighters were killed during the war, of whom about 1,400 were killed throughout southern Lebanon and another 1,000 killed during the Siege of Beirut. Gabriel also estimated that between 5,000 and 8,000 civilians died during the war. Some later estimates have put the total figure at 18-19,000 killed and more than 30,000 wounded, most of them civilians. 80% of villages in South Lebanon were damaged, with some completely destroyed. The Israeli government maintained that about 1,000 Palestinian fighters and 800 Lebanese civilians died during the invasion, excluding the siege of Beirut. Kenneth Pollack estimated that 1,200 Syrian soldiers were killed and about 3,000 wounded during the war.

Ex Output:
How many more PLO fighters were killed throughout southern Lebanon than during the Siege of Beirut?

Passage: Concerned by the Burmese consolidation of Shan states and Laotian states, China launched four invasions of Burma between 1765 and 1769. At first, the Qianlong Emperor envisaged an easy war, and sent in only the Green Standard troops stationed in Yunnan. The Qing invasion came as the majority of Burmese forces were deployed in their latest invasion of Siam. Nonetheless, battle-hardened Burmese troops defeated the first two invasions of 1765-1766 and 1766-1767 at the border. The regional conflict now escalated to a major war that involved military manoeuvres nationwide in both countries. The third invasion  led by the elite Manchu Bannermen nearly succeeded, penetrating deep into central Burma within a few days' march from Ava. But the Bannermen of northern China could not cope with unfamiliar tropical terrains and lethal endemic diseases, and were driven back with heavy losses. After the close-call, Hsinbyushin redeployed his armies from Siam to the Chinese front. The fourth and largest invasion got bogged down at the frontier. With the Qing forces completely encircled, a truce was reached between the field commanders of the two sides in December 1769.

Ex Output:
After how many Chinese invasions did the conflict escalate from a regional conflict into a major war?

Passage: From 1623 to 1624 the Dutch had been at war over the Pescadores, and in 1633 clashed with a fleet led by Zheng Zhilong in the Battle of Liaoluo Bay, ending in another Dutch defeat. By 1632 the Dutch had established a post on a peninsula named Tayoan , which was separated from the main part of Formosa by a shallow lagoon historically referred to as the Taikang inland sea . The Dutch fortifications consisted of two forts along the bay: the first and main fortification was the multiple-walled Fort Zeelandia, situated at the entrance to the bay, while the second was the smaller Fort Provintia, a walled administrative office. Frederick Coyett, the governor of Taiwan for the Dutch East India Company, was stationed in Fort Zeelandia with 1,800 men, while his subordinate, Valentyn, was in charge of Fort Provintia and its garrison of 500 men. In 1659, after an unsuccessful attempt to capture Nanjing, Koxinga, son of Zheng Zhilong and leader of the Ming loyalist remnants, felt that the Qing Empire had consolidated their position in China sufficiently, while his troops needed more supplies and manpower. He began searching for a suitable location as his base of operations, and soon a Chinese man named He Bin , who was working for the Dutch East India Company in Formosa , fled to Koxinga's base in Xiamen and provided him with a map of Taiwan.

Ex Output:

How many men did Coyett and Vlanetyn have?
