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 2007, Kuwait supplied China with  of oil per day, accounting for 2.6% of Chinas total crude oil imports.  Saudi Arabia was Chinas top supplier with its shipments jumping 69.8 percent to 3.84 million tons (939,000 bbl/d), followed by Angola with 2.06 million tons (503,000 bbl/d), down 27.1 percent. Iran became third, with imports from the country shrinking 35.3 percent to 1.18 million tons (289,000 bbl/d). China is the worlds second-biggest oil consumer after the US. Abdullatif Al-Houti, Managing Director of International Marketing at state-run Kuwait Petroleum Corporation (KPC), told KUNA in October that Kuwait is on course for its China-bound crude oil export target of  by 2015, but success will heavily depend on the Sino-Kuwaiti refinery project. The two countries have been in talks for the planned  refinery in Chinas southern Guangdong Province. The complex is expected to be on-stream by 2020.

SOLUTION: How many less tons of crude oil than Angola does Iran supply China?

PROBLEM: Passage: On November 2, Plymouth Colony governor Josiah Winslow led a combined force of colonial militia against the Narragansett tribe. The Narragansetts had not been directly involved in the war, but they had sheltered many of the Wampanoag fighters, women, and children. Some of their warriors had participated in several Indian attacks. The colonists distrusted the tribe and did not understand the various alliances. As the colonial forces went through Rhode Island, they found and burned several Indian towns which had been abandoned by the Narragansetts, who had retreated to a massive fort in a frozen swamp. The cold weather in December froze the swamp so that it was relatively easy to traverse. The colonial force found the Narragansett fort on December 19, 1675 near present-day South Kingstown, Rhode Island; they attacked in a combined force of Plymouth, Massachusetts, and Connecticut militia numbering about 1,000 men, including about 150 Pequots and Mohican Indian allies. The fierce battle that followed is known as the Great Swamp Fight. It is believed that the militia killed about 600 Narragansetts. They burned the fort  of land) and destroyed most of the tribe's winter stores. Most of the Narragansett warriors  escaped into the frozen swamp. The colonists lost many of their officers in this assault; about 70 of their men were killed and nearly 150 more wounded.  The rest of the colonial assembled forces returned to their homes, lacking supplies for an extended campaign. The nearby towns in Rhode Island provided care for the wounded until they could return to their homes.

SOLUTION: How many different militias did the force comprise of?

PROBLEM: Passage: The Crimean campaigns of 1687 and 1689  were two military campaigns of the Tsardom of Russia against the Crimean Khanate. They were a part of the Russo-Turkish War  and Russo-Crimean Wars. These were the first Russian forces to come close to Crimea since 1569. They failed due to poor planning and the practical problem of moving such a large force across the steppe but nonetheless played a key role in halting the Ottoman expansion in Europe. The campaigns came as a surprise for the Ottoman leadership, spoiled its plans to invade Poland and Hungary and forced it to move significant forces from Europe to the east, which greatly helped the League in its struggle against the Ottomans. Having signed the Eternal Peace Treaty with Poland in 1686, Russia became a member of the anti-Turkish coalition , which was pushing the Turks south after their failure at Vienna in 1683 . Russia's role in 1687 was to send a force south to Perekop to bottle up the Crimeans inside their peninsula.

SOLUTION:
How many campaigns were there?
