instruction:
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.
question:
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.
answer:
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?


question:
Passage: In 1976, the then Syrian president Hafez al-Assad sent troops into Lebanon to fight PLO forces on behalf of Christian militias. This led to escalated fighting until a cease-fire agreement later that year that allowed for the stationing of Syrian troops within Lebanon. The Syrian presence in Lebanon quickly changed sides; soon after they entered Lebanon they had flip-flopped and began to fight the Christian nationalists in Lebanon they allegedly entered the country to protect. The Kateab Party and the Lebanese Forces under Bachir Gemayel strongly resisted the Syrians in Lebanon. In 1989, 40,000 Syrian troops remained in central and eastern Lebanon under the supervision of the Syrian government. Although, the Taif Accord, established in the same year, called for the removal of Syrian troops and transfer of arms to the Lebanese army, the Syrian Army remained in Lebanon until the Lebanese Cedar Revolution in 2005 to end the Syrian occupation of Lebanon. In 1994, the Lebanese government under the pressure of the Syrian government, gave Lebanese passport to thousands of Syrians. There are nearly 1.08 million registered Syrian refugees in Lebanon.
answer:
Did the Syrians fight the Christians or protect them?
