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.

Input: Consider Input: 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.

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


Input: Consider Input: Passage: According to the Census Bureau, the median household income in 2013 was $36,836, down 7.9 percent from 2008 when the inflation-adjusted median household income was $40,008 (in 2013 dollars). For comparison, on an inflation-adjusted basis, the median household income among metropolitan areas was $60,482, down 8.2 percent in the same period, and the national median household income was $55,250, down 7.0 percent from 2008. The citys wealth disparity is evident when neighborhoods are compared. Residents in Society Hill had a 2013 median household income of $93,720, while residents in one of North Philadelphias districts reported the lowest median household income, $14,185.

Output: How many dollars difference is the 2013 median household income for the residents in Society Hill compared to the lowest median household income in one of North Philadelphia's districts?


Input: Consider Input: Passage: Early in the 1981-82 Los Angeles Lakers season, Johnson complained to the media about head coach Paul Westhead and demanded a trade. Westhead was fired shortly after Johnsons criticisms, and although Lakers owner Jerry Buss stated that Johnsons comments did not factor into the decision, Johnson was vilified by the national media and booed both on the road and at home. Buss promoted assistant coach Pat Riley to "co-head coach" with Jerry West (although West considered himself Rileys assistant) on November 19 and the team won 17 of its next 20 games. Nicknamed "Showtime (basketball)" due to the teams new Johnson-led fast break-offense, the Lakers won the Pacific Division title and swept both the 1981-82 Phoenix Suns season and 1981-82 San Antonio Spurs season in the 1982 NBA Playoffs. Los Angeles stretched its postseason winning streak to nine games by taking the first contest of the 1982 NBA Finals from the 1981-82 Philadelphia 76ers season. The team won the Finals 4-2 to finish a 12-2 playoff run. On draft night in 1982 NBA draft, the Lakers had the first overall pick (the result of a trade with Cleveland midway through the 1979-80 season, when the Lakers had sent Don Ford and a 1980 first-round pick to the Cavaliers for Butch Lee and their 1982 selection) and selected James Worthy from North Carolina Tar Heels mens basketball. The 1982-83 Los Angeles Lakers season won the Pacific Division at 58-24, but Worthy suffered a leg injury in the last week of the season and missed the rest of the season. Nevertheless, they advanced to play 1982-83 Philadelphia 76ers season in the 1983 NBA Finals after defeating 1982-83 Portland Trail Blazers season and 1982-83 San Antonio Spurs season. The Sixers, however, won the series and the championship in four games. After the season West replaced Sharman as the teams GM.


Output: How many games did the Lakers lose out of 20 after West and Riley were names co-head coaches?
