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: Japan, Canada and New Zealand are perceived as evolving destinations for international students. In 2006, Japan, Canada and New Zealand together shared roughly 13% of the international student market, with approximately 327,000 of the 2.7 million students who traveled abroad for the purposes of higher education. Japan has around 180 000 overseas students studying at its institutions and the government has set targets to increase this to 300, 000 over the next few years. Canada has seen a large increase in the number of Indian students, where the number of Indian students rose 280% in 2010 compared to 2008. Organizations such as Learnhub are taking advantage of this growing trend of Indian international students by providing recruitment services that bring Indian students abroad. In 2012, in Canada 10 percent of university students were international students.  Canada accepted more than 100,000 international students for the first time, bringing the total number of international students in Canada to 260,000, which is nearly identical to that of Australias 280,000. Recent changes to Canadas immigration regulations that came into effect on January 1, 2015 have placed international graduates from Canadian universities at a disadvantage. Under the new rules, foreign students who hold a degree or diploma from Canadian educational institutions will be treated on par with other groups of skilled workers.

Answer: How many countries are considered evolving destinations for international students?


Question: Passage: The Liberian economy had relied heavily on the mining of iron ore prior to the civil war. Liberia was a major exporter of iron ore on the world market. In the 1970s and 1980s, iron mining accounted for more than half of Liberia's export earnings. Since the coup d'état of 1980, the country's economic growth rate has slowed down because of a decline in the demand for iron ore on the world market and political upheavals in Liberia. Following a peak in growth in 1979, the Liberian economy began a steady decline due to economic mismanagement following the 1980 coup. This decline was accelerated by the outbreak of civil war in 1989; GDP was reduced by an estimated 90% between 1989 and 1995, one of the fastest declines in history. The United Nations imposed sanctions on Liberia in May 2001 for its support to the rebels of the Revolutionary United Front  in neighboring Sierra Leone. These sanctions have been lifted following elections in 2005. Upon the end of the war in 2003, GDP growth began to accelerate, reaching 9.4% in 2007. The global financial crisis slowed GDP growth to 4.6% in 2009, though a strengthening agricultural sector led by rubber and timber exports increased growth to 5.1% in 2010 and an expected 7.3% in 2011, making the economy one of the 20 fastest growing in the world. In March 2010, Bob Johnson, founder of BET, funded the first hotel constructed in Liberia in 20 years. The 13-acre  luxury resort was built in the Paynesville section of Monrovia. Liberia's external debt was estimated in 2006 at approximately $4.5 billion, 800% of GDP. As a result of bilateral, multilateral and commercial debt relief from 2007 to 2010, the country's external debt fell to $222.9 million by 2011.

Answer: How many percentage points did the GDP lose between 2007 and 2009?


Question: Passage: The Mughal power in northern India had been declining since the reign of Aurangzeb, who died in 1707. In 1751-52, the Ahamdiya treaty was signed between the Marathas and Mughals, when Balaji Bajirao was the Peshwa of the Maratha Empire. Through this treaty, the Marathas controlled large parts of India from their capital at Pune and Mughal rule was restricted only to Delhi . Marathas were now straining to expand their area of control towards the Northwest of India. Durrani sacked the Mughal capital and withdrew with the booty he coveted. To counter the Afghans, Peshwa Balaji Bajirao sent Raghunathrao. He succeeded in ousting Timur Shah and his court from India and brought northwest of India up to Peshawar under Maratha rule. Thus, upon his return to Kandahar in 1757, Durrani chose to return to India and confront the Maratha forces to regain northwestern part of the subcontinent. In 1761, Durrani set out on his campaign to win back lost territories. The early skirmishes ended in victory for the Afghans against the Maratha garrisons in northwest India. By 1759, Durrani and his army had reached Lahore and were poised to confront the Marathas. By 1760, the Maratha groups had coalesced into a big enough army under the command of Sadashivrao Bhau. Once again, Panipat was the scene of a battle for control of northern India. The Third battle of Panipat was fought between Durrani's Afghan forces and the Maratha forces in January 1761, and resulted in a decisive Durrani victory. This brought Punjab till north of Sutlej river under Afghan control. Ahmad Shah Durrani vacated Delhi soon after the battle. But the victory did not last, 10 years later the Maratha Empire recaptured lost lands.

Answer:
How many years after Durrani returned to Kandahar did he set out on a campaign to win back lost territories?
