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.

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

Passage: Regent Moray and his secretary John Wood tried to gain English support by producing the Casket letters in England, which were intended to incriminate Mary in the death of Lord Darnley. Moray also raised money in London by selling items from the Scottish crown jewels, including what was claimed to be a unicorn horn. Queen Elizabeth and her advisors were at first reluctant to intervene but their actions, and support of Moray, served to prevent reconciliation in Scotland. The Regent Moray was assassinated in January 1570 by a member of the Hamilton family. Elizabeth sent an army into Scotland in May 1570, which reached Glasgow, where the Queen's party were besieging Glasgow Castle. The army was commanded by the Earl of Sussex from Berwick, its leader in Scotland was William Drury, styled "Captain General." The Earl of Lennox was in their company, arriving at Edinburgh on 14 May 1570. The Marian lords abandoned their siege of Glasgow Castle before the English arrived on 18 May, and returned to their homelands, the Hamiltons to Arran and Craignethan Castle, and Drury attempted a siege of Dumbarton Castle. For Elizabeth's foreign policy this intervention had the effect of making France and Spain less likely to offer tangible pro-Marian support. After the Rising of the North and the discovery of the Ridolfi plot which further damaged Mary's reputation, Regent Mar and James Douglas, Earl of Morton were able to broker the deployment of an English army against Mary's supporters at Edinburgh Castle. The English diplomat Henry Killigrew worked on the reconciliation of the Scottish nobility at Perth in February 1572, where many promised not to support Mary as Queen. The fall of Edinburgh Castle concluded the civil war.
How did Moray die?
