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: The Broncos donned their alternate orange jerseys and kicked off their 2011 season at home against their AFC West rival Oakland Raiders, the Broncos' first Week 1 home opener since 2004. The Broncos took an early lead in the first quarter, with a 28-yard field goal by placekicker Matt Prater. The Raiders reeled off 16 unanswered points in the second quarter, with a 3-yard touchdown pass from quarterback Jason Campbell to fullback Marcel Reece, followed by three field goals of 37, 21 and 63 yards by placekicker Sebastian Janikowski, the latter of which tied the record for the longest field goal in NFL history. The Broncos responded in the third quarter, with kick returner Eric Decker returning a punt 90 yards for a touchdown, followed by a 30-yard field goal by Prater. The Raiders increased their lead in the fourth quarter, with a 1-yard touchdown run by Campbell. The Broncos tried to rally, with quarterback Kyle Orton throwing a 9-yard touchdown pass to running back Lance Ball. However, Oakland would run out the clock.
How many field goals between 25 and 65 yards were made?

Passage: All these problems came to a head on 1 June 1648, upon Alexei I's return to Moscow from the Troitse-Sergiyeva Lavra monastery. A crowd of Muscovites surrounded the Tsar and complained about the boyars and prikaz officials. Instead of hearing the petition, the royal bodyguards started dispersing the crowd, pushing them away from the Tsar. This unexpected reaction caused a major outbreak of anger among the people. On 2 June the insurgents burst into the Moscow Kremlin and demanded the surrender of Leontii Pleshcheyev , Duma diak Nazar Chistoy , boyar Boris Morozov  and his brother-in-law Pyotr Trakhaniotov . Morozov commanded the Streltsy  to drive the rioters out of the Kremlin, but they refused. When not acting as the Tsar's bodyguards, the musketeers held artisanal jobs in Moscow. This conflict of interest led them to side with the plight of the townsmen, stating that they, "...did not want to stand in antagonistic relations with the crowd for the sake of the traitor and tyrant Pleshcheyev." The people would not hear the Tsar's heartfelt pleas to spare Pleshceyev and, on June 3, Alexei surrendered the official. In their fervor, the crowd did not wait for Pleshcheyev to be executed instead, "...they cuggeled him so black and blue and with axes they cut him asunder like a fish, the pieces they let lie naked here and there." The rebels set fire to the White City and Kitai-gorod. They burned between 15,000 and 24,000 houses; between 1700 and 2000 people died in the riot. The rioters split into two groups to target the most hated boyars, diaks, okolnichys, and merchants, killing Nazar Chistoy as he begged for mercy. When rumors spread that Morozov's men had started the fires to antagonize the rioters, the boyar head hunt gained greater momentum.

How did the rioters execute Pleshceyev?
