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.

[EX Q]: 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.
[EX A]: How many percentage points did the GDP lose between 2007 and 2009?

[EX Q]: Passage: The Redskins entered this Week 1 matchup against the Steelers having lost five consecutive games against Pittsburgh dating back to 1991. They scored an average of 8.2 points per game in those five losses. The Redskins' 22-point defeat was their worst in a Week 1 game in 15 years. It was also their worst opening day home loss since 1966. The Redskins defense had a very hard time containing DeAngelo Williams as he exploded for 143 rushing yards and the Steelers explosive receiving corps of Antonio Brown and Eli Rogers who would go on to have strong performances.
[EX A]: How many losses did the Redskins have?

[EX Q]: Passage: Compared with its metropolitan area, the city of Houstons population has a higher proportion of minorities. According to the 2010 United States Census, whites made up 51% of the city of Houstons population; 26% of the total population was non-Hispanic whites. Blacks or African Americans made up 25% of Houstons population, Native Americans in the United States made up 0.7% of the population,  Asians made up 6% (1.7% Vietnamese Americans, 1.3% Chinese Americans, 1.3% Indian Americans, 0.9% Pakistani Americans, 0.4% Filipino Americans, 0.3% Korean Americans, 0.1% Japanese Americans) and Pacific Islanders made up 0.1%. Individuals from some other race made up 15.2% of the citys population, of which 0.2% were non-Hispanic. Individuals from two or more races made up 3.3% of the city.
[EX A]:
