instruction:
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: A 2013 analysis of the National Assessment of Educational Progress found that from 1971 to 2008, the size of the black-white IQ gap in the United States decreased from 16.33 to 9.94 IQ points. It has also concluded however that, while IQ means are continuing to rise in all ethnic groups, this growth is occurring more slowly among 17-year-old students than among younger students and the black-white IQ gap is no longer narrowing. As of 2008, a study published in 2013 by Heiner Rindermann, Stefan Pinchelmann, and James Thompson have estimated the IQ means of 17-year-old black, white, and Hispanic students to range respectively from 90.45-94.15, 102.29-104.57 and 92.30-95.90 points. They explain that the gap may persist due to the crack epidemic, the degradation of African-American family structure, the rise of fraud in the educational system (especially with respect to No Child Left Behind), the decrease in unskilled real wages and employment among African-Americans due to globalization and minimum wage increases, differences in parental practices (such as breastfeeding or reading to children), and "environmental conditions shaped by [African-Americans] themselves." To resolve this, they ultimately recommend the reestablishment of "meritoric principles" and "blindly graded objective central exams," as opposed to "affirmative action," in education.
answer:
How many IQ points did the black-white IQ gap decrease between 1971 and 2008?


question:
Passage: On December 7, 2015, the Washington Post reported that since 2001, in five theaters of the war  that the total number of terrorists killed ranges from 65,800 to 88,600, with Obama administration being responsible for between 30,000 and 33,000.
answer:
About how many terrorists (minimum) were killed by administrations before the Obama administration?


question:
Passage: Wind energy is generated by local wind farms. The largest, Waubra Wind Farm, completed in 2009, ( W - 192 MW, 128 turbines) is capable of producing enough electricity to power a city 3 to 4 times the size of Ballarat. Other significant nearby wind farms include Mount Mercer Wind Farm, completed 2014, ( S - 131 MW, 64 turbines) which produces enough energy to power 100,000 homes, equivalent to Ballarats population and Chepstowe, completed March 2015, ( W - 6 MW, 3 turbines) which produces enough power for 3,400 homes. The first community-owned wind farm in Australia, the Hepburn Wind Project at Leonards Hill, Victoria, completed in 2011, ( NE - 4 MW, 2 turbines) produces the equivalent amount of electricity used by the town of Daylesford, Victoria. Several large projects have planning approval, including Stockyard Hill Wind Farm ( W - 41 MW, 157 turbines), Moorabool Wind Project at Mount Egerton, Victoria and Ballan, Victoria ( E - 330 MW, 107 turbines). and the Lal Lal, Victoria Wind Farm ( SE - 150 MW, 64 turbines).
answer:

How many total turbines will be used in the three planned projects?
