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'etat 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 eventual configuration was rare in terms of contemporary fighter aircraft design, with only the preceding Fokker G.1, the contemporary Focke-Wulf Fw 189 Luftwaffe reconnaissance aircraft, and the later Northrop P-61 Black Widow night fighter having a similar planform (aeronautics). The Lockheed team chose twin booms to accommodate the tail assembly, engines, and turbo-superchargers, with a central nacelle for the pilot and armament. The XP-38 gondola mockup was designed to mount two .50-caliber (12.7 mm) M2 Browning machine guns with 200 rounds per gun (rpg), two .30-caliber (7.62 mm) Brownings with 500 rpg, and a T1 Army Ordnance 23 mm (.90 in) autocannon with a rotary magazine as a substitute for the non-existent 25 mm Hotchkiss et Cie aircraft autocannon specified by Kelsey and Saville. In the YP-38s, a M4 cannon with 15 rounds replaced the T1. The 15 rounds were in three five-round clips, an unsatisfactory arrangement according to Kelsey, and the M9 did not perform reliably in flight. Further armament experiments from March to June 1941 resulted in the P-38E combat configuration of four M2 Browning machine guns, and one Hispano-Suiza HS.404 20 mm (.79 in) autocannon with 150 rounds.

Answer: How many weapons did the P-38E have in its last configuration?

Question: Passage: The second half of the war was initiated by Pegu. To take advantage of Ava's dynastic succession crisis, Razadarit invaded Upper Burma in full force with a large flotilla in 1401. Ava's defenses held, and Razadarit and Minkhaung I of Ava agreed to another truce in 1403. The second truce lasted less than 5 years as Ava quickly went on an expansion spree, swallowing up Shan states of Kale and Mohnyin in the north, and Arakan in the west, between 1404 and 1406. Pegu could not allow Ava to get too strong, and renewed the war. In 1408, Peguan forces dislodged Avan troops from Arakan. Pegu also found an ally in the Shan state of Theinni , which too wanted to check Ava's ambitions. Between 1408 and 1413, Ava was forced to fight on multiple fronts: Theinni in the north, and Pegu in the south and in the west . Nonetheless, by 1412, Avan forces, led by Crown Prince Minye Kyawswa, had begun to gain an upper hand. Minye Kyawswa defeated Theinni and its Chinese allies in 1412. He invaded the Hanthawaddy country in full force in 1414, and conquered the Irrawaddy delta in 1415, forcing Razadarit to flee Pegu for Martaban. But Minye Kyawswa was killed in battle in March 1415.

Answer:
After Razadarit invaded Upper Burma in full force with a large flotilla in 1401, how many years until another truce was agreed upon?
