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.

[EX Q]: 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.
[EX A]: Did the Syrians fight the Christians or protect them?

[EX Q]: Passage: Since 1999, the overall crime rate of Charleston has declined markedly. The total crime index rate for Charleston in 1999 was 597.1 crimes committed per 100,000 people, while in 2011, the total crime index rate was 236.4 per 100,000.
[EX A]: How many crimes committed per 100000 people lower was the rate in 2011 versus 1999?

[EX Q]: Passage: The Crimean Tatar's invasions of Russia  began in 1507, after the death of Moscow's grand duke Ivan III, with the Crimean Khanate attacking the Russian towns of Belev and Kozelsk. Over the course of the 16th century, the outer border of the Wild Steppes was near the city of Ryazan, outside the Oka River. The main path for the invading forces to Moscow was the Muravsky Trail, running from the Crimean Isthmus of Perekop, between the basins of the Dnieper and Severskiy Donets rivers, and finally up to Tula. The Tatars would turn back only after extensive looting and kidnapping, the Tartars usually managed to penetrate 100-200 kilometers into Russian territory. Captives were subsequently sent to the Crimean city of Caffa to be sold into Slavery. As a result, the Russian population in the border regions suffered heavily. Each spring, Russia mobilized up to 65,000 soldiers for border service. The defensive lines consisted of a circuit of fortresses and cities. To protect from invasions by the Nogai Horde in the region between the Volga and Irtysh rivers, the Volga cities of Samara , Tsaritsyn , and Saratov  were founded. The most damaging invasions occurred in 1517, 1521 , 1537 , 1552, 1555, 1570-72 , 1589, 1593, 1640, 1666-67 , 1671, and 1688.
[EX A]:
How many Volga cities were founded to protect from invasions by the Nogai Horde?
