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: The rebellion in Hauran erupted in May 1909, when a business dispute between Druze chief Yahia bey Atrash in the village of Busra al-Harir escalated into a clash of arms between the Druze and Ottoman-backed local villagers. A year of truce attempts followed, but failed to achieve any stability in the area and prompting an Ottoman response. Sami Pasha al-Farouqi arrived in Damascus in August 1910, leading an Ottoman expeditionary force of some 35 battalions. Though the Druze recognized their inferiority against such a force, several clashes followed. Zuqan al-Atrash led a fierce battle against the Ottomans near al-Kafr, where he faced the forces of Sami Pasha al-Farouqi. After engaging Ottoman troops in two villages the Druze resistance collapsed. Sami Pasha used military force and trickery and succeeded in occupying the whole Jabal el-Druze. The rebellion ended with massive casualties among the Druze inhabitants of the Hauran, reaching as much as 10% of the population. The number of killed is put at 2,000 with a similar number of wounded and hundreds of imprisoned, taken into custody in Damascus and Acre. This led to significant depopulation of entire areas within the region. Zuqan, the leader of the revolt, was captured and later executed in 1911 .
answer:
How many years after the rebellion in Hauran erupted in 1909 did Zuqan, the leader of the revolt, get executed?


question:
Passage: There are 186,440 people (up from 181,743 in 2000), 75,177 households, and 57,543 families residing in the city. This amounts to 6.75% of Utahs population, 18.11% of Salt Lake Countys population, and 16.58% of the new Salt Lake metropolitan population. The area within the city limits covers 14.2% of Salt Lake County. Salt Lake City is more densely populated than the surrounding metro area with a population density of 1,688.77/sq mi (1,049.36/km²). There are 80,724 housing units at an average density of 731.2 per square mile (454.35/km²).
answer:
By how many people did the city grow since 2000?


question:
Passage: Attitudes toward marriage have changed substantially since World War II. Most obvious was the declining marriage rate, which dropped from 8.5 marriages per 1,000 Finns in 1950 to 5.8, in 1984, a decline great enough to mean a drop also in absolute numbers. In 1950 there were 34,000 marriages, while in 1984 only 28,500 were registered, despite a growth in population of 800,000. An explanation for the decline was that there was an unprecedented number of unmarried couples. Since the late 1960s, the practice of cohabitation had become increasingly common, so much so that by the late 1970s most marriages in urban areas grew out of what Finns called "open unions." In the 1980s, it was estimated that about 8 percent of couples who lived together, approximately 200,000 people, did so without benefit of marriage. Partners of such unions usually married because of the arrival of offspring or the acquisition of property. A result of the frequency of cohabitation was that marriages were postponed, and the average age for marriage, which had been falling, began to rise in the 1970s. By 1982 the average marriage age was 24.8 years for women and 26.8 years for men, several years higher for both sexes than had been true a decade earlier.
answer:

By how many years did the marriage age for women and men differ in 1982?
