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.

Q: Passage: After a tough road loss to the Ravens, the Steelers went home for a game against the Dolphins.  They would score first as Ben Roethlisberger found Emmanuel Sanders on a 5-yard pass for a 7-0 lead.  The Dolphins managed to get on the board as Caleb Sturgis kicked a 30-yard field goal making the score 7-3.  In the 2nd quarter, Charles Clay caught a 6-yard touchdown pass from Ryan Tannehill as the Phins took the lead 10-7 at halftime.  After the break, the Dolphins went right back to work as Daniel Thomas ran for a 4-yard touchdown making the score 17-7.  The Steelers then came within 3 when Roethlisberger found Antonio Brown on a 43-yard touchdown pass making the score 17-14 and would eventually score again when Troy Polamalu picked off Tannehill and returned it 19 yards for a touchdown as they retook the lead 21-17.  The Dolphins however moved back into the lead as Tannehill found Brian Hartline on a 4-yard pass for a 24-21 score.  In the 4th quarter, Roethlisberger found Jerricho Cotchery on a 16-yard touchdown pass as they moved ahead 28-24.  Clay then caught a pass from Tannehill making the score 31-28 as the Dolphins retook the lead.  They would stop scoring after Sturgis kicked a 27-yard field goal for a 34-28 lead.  Under a minute to go in the quarter, the Steelers got the ball back with Roethlisberger throwing to Brown and then Brown running for what seemed to be the game-tying (and eventually game-winning touchdown and PAT), but officials reviewed the play and it was determined that Brown had stepped out of bounds during the run ending the game dropping the team to 5-8.

A: How many field goals did Sturgis kick?

Q: 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.

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

Q: Passage: With the 1335 Treaty of Trentschin and the 1348 Treaty of Namslau, most of the Silesian duchies were ruled by the Silesian Piast dukes under the feudal overlordship of the Bohemian kings, and thus became part of the Crown of Bohemia. In 1476 the Crossen district became part of the Margraviate of Brandenburg, when the widow of the Piast ruler, Barbara von Brandenburg, daughter of Elector Albert Achilles, inherited Crossen. In 1526 Silesia was acquired by Austria's Habsburg Monarchy after the death of King Louis II of Bohemia. Brandenburg contested the inheritance, citing a treaty made with Frederick II of Legnica, but Silesia largely remained under Habsburg control until 1742.

A:
How many years after Silesia was acquired by Austria's Habsburg Monarchy did Silesia largely remained under Habsburg control?
