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 Q]: Passage: Just days after teammate Sean Taylor died of his injuries, the Redskins tried to snap a three-game skid at home against the Buffalo Bills. Before the kickoff, the stadium held a memorial service for Sean Taylor, as well as players across the NFL wearing a #21 sticker on the back of their helmets. For the team's first defensive play, they would come out with only 10 players on the field, as their honor to Taylor. In the first quarter, the Redskins took the early lead as kicker Shaun Suisham managed to get a 27-yard field goal for the only score of the quarter. In the second quarter, the Redskins increased their lead as Suisham kicked a 28-yard field goal. Later, the Bills got on the board as linebacker Angelo Crowell sacked quarterback Jason Campbell in his end zone for a safety. The Redskins would end the half as Suisham kicked a 33-yard field goal. In the third quarter, the Bills drew closer as kicker Rian Lindell managed to get a 38-yard field goal. Later, the Redskins responded with running back Clinton Portis getting a 3-yard touchdown run. Afterwards, the Bills ended the half as Lindell kicked a 43-yard field goal. In the fourth quarter, the Bills drew closer as Lindell kicked a 24-yarder, along with a 33-yard field goal. Later, the Bills got into position to kick a 51-yard field goal. They got the kick, but Head Coach Joe Gibbs called timeout. When the Bills tried to kick again, Gibbs called timeout again, but unintentionally got his team an unsportsmanlike conduct penalty which not only moved the Bills 15 yards closer to their end zone but reduced Lindell's field goal attempt to 36 yards. Afterwards, the Bills ended the game with Lindell nailing the game-winning 36-yard field goal.
[EX A]: How long was the longest field goal?

[EX Q]: 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 A]: After how many Chinese invasions did the conflict escalate from a regional conflict into a major war?

[EX Q]: Passage: The Peru-Bolivian Confederation was a short-lived state that existed in South America between 1836 and 1839. The country was a loose confederation between the states of Peru, divided into the Republic of North Peru and the Republic of South Peru, and Bolivia, with the capital located in Tacna. The Peru-Bolivian Confederation's formation was personally influenced by Marshal Andrés de Santa Cruz, the President of Bolivia, who served as the first and only head of state under the title "Supreme Protector". The Peru-Bolivian Confederation was opposed by neighboring countries from its inception, particularly Chile and Argentina, as a potential military and economic threat, and for its support for dissidents in exile. The War of the Confederation was triggered shortly after its formation when Chile and Argentina independently invaded the country. Argentina was defeated in 1837, but a combined force of Chile and North Peruvian dissidents known as the United Restoration Army were victorious at the Battle of Yungay in January 1839, which de facto ended the confederation as Peru and Bolivia were restored as independent states, and Santa Cruz fled into exile. The Peru-Bolivian Confederation was officially declared dissolved on August 25, 1839, by General Agustín Gamarra after his appointment as President of Peru.
[EX A]:
How many countries particularly opposed the Peru-Bolivian Confederation?
