TASK DEFINITION: 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.
PROBLEM: 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.

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

PROBLEM: Passage: Trying to rebound from their road loss to the Packers, the Redskins went home for a Week 7 match-up against the Arizona Cardinals. In the first quarter, Washington took the early lead with running back Clinton Portis getting a 2-yard touchdown run for the only score of the quarter. In the second quarter, the Redskins increased its lead with linebacker London Fletcher returning an interception 27 yards for a touchdown. The Cardinals would get a touchdown as quarterback Kurt Warner completed a 2-yard touchdown pass to wide receiver Anquan Boldin (with a failed PAT). In the third quarter, Washington increased its lead with Portis getting a 1-yard touchdown run for the only score of the quarter. In the fourth quarter, the Cardinals managed to get within striking distance as quarterback Warner and wide receiver Boldin hooked up on a 10-yard touchdown pass. Afterwards, the Cardinals got within two points with quarterback Tim Rattay completing a 1-yard touchdown pass to tight end Leonard Pope (with a failed 2-point conversion). Later, the Cardinals managed to recover its onside kick and managed to set up a game-winning 55-yard field goal. Fortunately for the Redskins: the Cardinals' kick missed wide left&#8212;securing the victory.

SOLUTION: How did the Cardinals lose the game?

PROBLEM: Passage: The Authorization for Use of Military Force Against Terrorists or "AUMF" was made law on 14 September 2001, to authorize the use of United States Armed Forces against those responsible for the attacks on 11 September 2001.It authorized the President to use all necessary and appropriate force against those nations, organizations, or persons he determines planned, authorized, committed, or aided the terrorist attacks that occurred on 11 September 2001, or harbored such organizations or persons, to prevent any future acts of international terrorism against the United States by such nations, organizations or individuals. Congress declares this is intended to constitute specific statutory authorization within the meaning of section 5 of the War Powers Resolution of 1973. The George W. Bush administration defined the following objectives in the War on Terror:.

SOLUTION:
How many days after the 9/11 attacks was the AUMF made into law?
