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.

Example Input: Passage: Still trying to get their first win, the Dolphins flew to Wembley Stadium for their special international interconference game against the New York Giants.  For the game, Miami was listed as the home team.  In the first quarter, the Dolphins trailed early as Giants kicker Lawrence Tynes nailed a 20-yard field goal for the only score of the period.  In the second quarter, Miami's struggles continued with N.Y. QB Eli Manning getting a 10-yard TD run, along with Tynes nailing a 41-yard field goal. In the third quarter, the 'Fins started to make a comeback as former Giants kicker Jay Feely got a 29-yard field goal for the only score of the period.  In the fourth quarter, Miami drew close as QB Cleo Lemon completing a 21-yard TD pass to rookie WR Ted Ginn, Jr.  However, New York managed to hold on to their lead for the win. With their 11th-straight loss, the Dolphins entered their bye week at 0-8.
Example Output: How many field goals between 25 and 45 were scored?

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

Example Input: Passage: The revenue of Pahang in 1899 amounted to only $62,077; in 1900 to $419,150.  In 1905 it was $528,368.  The expenditure in 1905 amounted to $1,208,176.  Of this sum $736,886 was expended on public works.  Pahang is still a source of expense to the federation, its progress having been retarded by the disturbances which lasted from December 1891 until 1895, with short intervals of peace, but the revenue was steadily increasing, and the ultimate financial success of the state is considered to be secure.  Pahang owed something over $3,966,500 to Selangor and $1,175,000 to Perak, which had financed it for some years out of surplus revenue.  The value of the imports in 1905 was $1,344,346, that of the exports was $3,838,928, thus making a total trade value of $5,183,274.  The most valuable export is tin, the value of which in 1905 amounted to $2,820,745. The value of the gutta exported exceeded $140,000, that of dried and salted fish amounted to nearly $70,000, and that of timber to $325,000.
Example Output:
How many dollars higher was the revenue of Pahang in 1900 compared to 1899?
