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: 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.
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?

Passage: On 4 November 1309, Pope Clement admitted what had long been suspected, that the Hospitaller expedition would not go to the Holy Land. It was merely a preparatory campaign to help defend Cyprus and enforce the prohibition on Catholics trading with Muslims. The official expedition was ready to sail from the Italian port of Brindisi in January 1310, but was delayed until spring by bad weather. It was under the direct command of the grand master, Foulques de Villaret, who was accompanied by a papal legate, Pierre de Pleine-Chassagne. The force contained 26 galleys , two or three hundred knights and about three thousand foot soldiers. When the fleet sailed it was still unknown where Villaret planned to take it. Rather than go to the Holy Land, it sailed for the Byzantine island of Rhodes. It was in Greek waters on 13 May, when Villaret sent a message of peace to Venice. The crusader army participated in the final conquest of the city of Rhodes in August. Although no expedition to the Holy Land came out of the preaching of 1308-9, Rhodes was a strategically important base for future campaigns and the Hospitallers made it their headquarters in 1311.
How many years did these events take?

Passage: The election of Ernst of Bavaria expanded the local feud into a more German-wide phenomenon. The pope committed 55,000 crowns to pay soldiers to fight for Ernst, and another 40,000 directly into the coffers of the new Archbishop. Under the command of his brother, Ernst's forces pushed their way into Westphalia, threatening Gebhard and Agnes at their stronghold at Arensburg. Gebhard and Agnes escaped to the rebellious provinces of the Netherlands with almost 1000 cavalry, where Prince William gave them a haven in Delft. There, Gebhard solicited the impecunious William for troops and money. After William's assassination in July 1584, Gebhard wrote to Queen Elizabeth requesting assistance. Elizabeth responded toward the end of 1585, directing him to contact Robert Dudley, 1st Earl of Leicester, her deputy with the rebellious Dutch, and recently commissioned as the commander-in-chief of her army in the Netherlands. Elizabeth had her own problems with adherents of her cousin Mary, Queen of Scots, and the Spanish.

Did Elizabeth respond to Gebhard before or after the assassination of Prince William?
