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: The U.S. Institute of Medicine (IOM) updated Estimated Average Requirements (EARs) and Recommended Dietary Allowances (RDAs) for iron in 2001. The current EAR for iron for women ages 14–18 is 7.9 mg/day, 8.1 for ages 19–50 and 5.0 thereafter (post menopause). For men the EAR is 6.0 mg/day for ages 19 and up. The RDA is 15.0 mg/day for women ages 15–18, 18.0 for 19–50 and 8.0 thereafter. For men, 8.0 mg/day for ages 19 and up. RDAs are higher than EARs so as to identify amounts that will cover people with higher than average requirements. RDA for pregnancy is 27 mg/day and, for lactation, 9 mg/day. For children ages 1–3 years 7 mg/day, 10 for ages 4–8 and 8 for ages 9–13. As for safety, the IOM also sets Tolerable upper intake levels (ULs) for vitamins and minerals when evidence is sufficient. In the case of iron the UL is set at 45 mg/day. Collectively the EARs, RDAs and ULs are referred to as Dietary Reference Intakes.
[A]: How many mg higher is the RDA for women aged 19-50 than for men 19 and older?


[Q]: Passage: Hoping to increase their winning streak the Chargers moved to Reliant Stadium for an AFC duel with the Texans. In the first quarter the Chargers trailed early as RB Arian Foster got an 8-yard TD run. They soon replied with QB Philip Rivers making a 55-yard TD pass to WR Seyi Ajirotutu. They trailed again with kicker Neil Rackers nailed a 27-yard field goal, but took the lead after Rivers got an 11-yard TD pass to TE Randy McMichael. They fell behind again in the second quarter as Foster made a 2-yard TD run, followed by Rackers hitting a 21 and a 25-yard field goal. The Chargers eventually pulled themselves in front again, with Rivers finding McMichael again on a 12-yard TD pass. This was followed in the 4th quarter by Rivers' 28-yard TD pass to Ajirotutu (With a successful 2-point conversion as FB Mike Tolbert ran to the endzone). With the win, the Chargers went into their bye week at 4-5.
[A]: How many TD passes did Rivers complete?


[Q]: Passage: Discovery of gold in the Boise Basin in 1862 brought settlement to the region again.  The lower Boise River was fully contained within Boise County from 1863 until the formation of Ada in 1864. Settlement of the lower Boise River west of Boise City was limited prior to the completion of the Oregon Shortline railroad.  Middleton was the first settlement of Canyon County, starting in 1863. The 1870 Census for Ada County listed 76 residents of the Boise Valley, excluding Boise City and the 1880 Census listed 44 residents at Middleton.  The arrival of the Railroad at Caldwell led to the establishment of a town there as of August, 1883.  Businessmen James A. McGee and Alexander Duffes filed the plat for nearby Nampa in 1886.  Parma was settled around the same time with the Old Fort Boise post office being moved to the towns location.  It was incorporated in 1904.  Ada County established precincts for each of the settlements with a combined 1890 Census population of 2,311.  Significant settlement of Greenleaf and Notus started around 1904 with the two settlements listed as precincts at the 1910 census.  Notus was incorporated in 1921 while Greenleaf was incorporated prior to 1980.  Melba was incorporated in 1912 while Wilder was incorporated in 1919.  The City of Star annexed a portion of territory in northeast Canyon County prior to 2007, becoming the countys ninth incorporated city.  The majority of Star is located within Ada County.
[A]:
How many settlements were listed as precincts at the 1910 census?
