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 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: From 1623 to 1624 the Dutch had been at war over the Pescadores, and in 1633 clashed with a fleet led by Zheng Zhilong in the Battle of Liaoluo Bay, ending in another Dutch defeat. By 1632 the Dutch had established a post on a peninsula named Tayoan , which was separated from the main part of Formosa by a shallow lagoon historically referred to as the Taikang inland sea . The Dutch fortifications consisted of two forts along the bay: the first and main fortification was the multiple-walled Fort Zeelandia, situated at the entrance to the bay, while the second was the smaller Fort Provintia, a walled administrative office. Frederick Coyett, the governor of Taiwan for the Dutch East India Company, was stationed in Fort Zeelandia with 1,800 men, while his subordinate, Valentyn, was in charge of Fort Provintia and its garrison of 500 men. In 1659, after an unsuccessful attempt to capture Nanjing, Koxinga, son of Zheng Zhilong and leader of the Ming loyalist remnants, felt that the Qing Empire had consolidated their position in China sufficiently, while his troops needed more supplies and manpower. He began searching for a suitable location as his base of operations, and soon a Chinese man named He Bin , who was working for the Dutch East India Company in Formosa , fled to Koxinga's base in Xiamen and provided him with a map of Taiwan.

Answer: How many men did Coyett and Vlanetyn have?

Their 34-24 victory came after an interception by NaVorro Bowman with 1:28 left in the game. The play would seal a win for a playoff spot for the 49ers and is called The Pick at the Stick by some sports columnists. This game was also Candlestick Park's 36th and final game on Monday Night Football, the most at any stadium used by the NFL.
