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.

Q: 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.

A: How many IQ points did the black-white IQ gap decrease between 1971 and 2008?

Q: Passage: More than 5,000 US troops of General John J. Pershing's forces, including elements of the 7th Cavalry and the African-American U.S. 10th Cavalry Regiment, entered Mexico in hot pursuit of Villa. The campaign consisted primarily of dozens of minor skirmishes with small bands of insurgents. Gen. Pershing failed to catch up to Villa. On 21 June 1916, two troops of the 10th, totaling 92 troopers, attacked Mexican Federal Army troops in an engagement in the Battle of Carrizal, Chihuahua. 12 US troops were killed and 23 taken prisoner; 45 Federales were casualties, including the Mexican general Gomez. The engagement nearly precipitated open war with the Mexican government , but both governments immediately moved to lessen tensions and open negotiations for US withdrawal, preventing war. The prisoners were repatriated at El Paso, Texas by the Carrancista government.

A: How many US troops in the Battle of Carrizal, Chihuahua were killed or taken prisoner?

Q: Passage: The war mobilization dramatically expanded union membership, from 8.7 million in 1940 to over 14.3 million in 1945, about 36% of the work force. For the first time large numbers of women factory workers were enrolled. Both the AFL and CIO supported Roosevelt in 1940 and 1944, with 75% or more of their votes, millions of dollars, and tens of thousands of precinct workers. However, Lewis opposed Roosevelt on foreign policy grounds in 1940. He took the Mine Workers out of the CIO and rejoined the AFL. All labor unions strongly supported the war effort after June 1941 . Left-wing activists crushed wildcat strikes. Nonetheless, Lewis realized that he had enormous leverage. In 1943, the middle of the war, when the rest of labor was observing a policy against strikes, Lewis led the miners out on a twelve-day strike for higher wages. The bipartisan Conservative coalition in Congress passed anti-union legislation over liberal opposition, most notably the Taft-Hartley Act of 1947. A statistical analysis of the AFL and CIO national and local leaders in 1945 shows that opportunity for advancement in the labor movement was wide open. In contrast with other elites, the labor leaders did not come from established WASP families with rich, well-educated backgrounds. Indeed, they closely resembled the overall national population of adult men, with fewer from the South and from farm backgrounds. The union leaders were heavily Democratic. The newer CIO had a younger leadership, and one more involved with third parties, and less involved with local civic activities. Otherwise the AFL and CIO leaders were quite similar in background.

A:
After Lewis' strike in 1943, how many years passed before Congress passed the Taft-Hartlet Act?
