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: In order to regain control of the custom duties, the emperor John VI Kantakouzenos made preparations to lower Constantinople's duties and most tariffs to undercut the Genoese in Galata. Still recovering from the civil war of 1341-1347, the emperor, with great difficulty, raised 50,000 hyperpyra from private sources  for a shipbuilding program for the expected war to come. When the tariffs and custom duties were finally lowered, merchant shipping coming through the strait bypassed Genoese Galata and diverted their ships across the Golden Horn to Byzantine Constantinople. The Genoese, financially hard-hit from this policy, declared war on the Empire, and in August 1348, a flotilla of ships sailed across the Horn and attacked the Byzantine fleet; despite their large scale preparations, the Byzantine fleet was destroyed by early 1349. The Byzantines retaliated by burning wharves and warehouses along the shore and catapulted stones and burning bales of hay into Galata, setting major parts of the city on fire. After several weeks of fighting, plenipotentiaries from Genoa came and negotiated a peace agreement. The Genoese agreed to pay a war indemnity of 100,000 hyperpyra and evacuated the land behind Galata which they illegally occupied; last, they promised never to attack Constantinople. In return the Byzantines surrendered nothing, but the Genoese custom duties remained in effect.

Ex Output:
Approximately how many years did it take for the Byzantine fleet to be destroyed after August 1348?

Passage: In week 9, the Lions hosted an interconference duel against the New York Jets. The only score of the first quarter was a 10-yard TD catch by the Lions' Brandon Pettigrew. The Jets responded in the second quarter with a 31-yard field goal by Nick Folk and later a 74-yard TD catch by Braylon Edwards just before halftime. The only score of the third quarter was a 1-yard quarterback sneak TD by Matt Stafford of the Lions; however the extra point attempt by defensive lineman Ndamukong Suh (an emergency fill-in for injured kicker Jason Hanson, who got run into on the previous field goal attempt which gave them a fresh set of downs) was no good. Early in the fourth quarter, the Lions added to their lead with a Nate Burleson 2-yard TD catch. The Jets responded late in the quarter with a 1-yard TD quarterback sneak by Mark Sanchez. The Jets kicked a field goal to tie it up just before time expired, forcing overtime. The Jets won the toss and kicked a 30-yard field goal for the win as the Lions fell to 2-6.

Ex Output:
How many 1-yard quarterback sneaks were in the game?

Passage: The Siamese too had been busy planning their defences since Hsinbyushin accession. Their defences had been on alert since they got the Tavoy governor to revolt in mid-1764. King Ekkathat had already launched a massive mobilisation drive across the entire country when Maha Nawrahta came down with his army and retook Tavoy in November 1764. In all, the Siamese southern defences alone comprised over 60,000 troops. Ekkathat placed several of "his best legions" along the entire western arc from the Three Pagodas Pass to Kanchanaburi across Tavoy, to the Gulf of Siam in the extreme south to face off Maha Nawrahta. In the north, the main Siamese defensive line began at Sukhothai and Phitsanulok. The defences farther north immediately facing the northern Burmese army relied on small forts built by local chiefs. Finally, the Siamese relied on a heavily fortified Ayutthaya city, strategically situated at the estuary of two rivers where high rising waters in the rainy season had kept it safe against enemies over the centuries. The Siamese had used their wealth to acquire several thousand muskets and artillery. Some of the cannon were thirty feet  long, and fired 100-lb.  balls.  As was the case in 1760, foreign mercenaries  were hired for Ayutthaya's defence. At least one English ship was enlisted for her broadsides.

Ex Output:

How many years passed between the foreign mercenaries being hired for Ayutthaya's defense and the retaking of Tavoy?
