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: Coming off of their home win over the Lions, the Cardinals flew to the Hubert H. Humphrey Metrodome for a Week 12 fight with the Minnesota Vikings.  This game was noted for the return of head coach Green to Minnesota where he coached from 1992 to 2001.  On the very first play of the first quarter, RB J.J. Arrington returned a kickoff 99 yards for a touchdown.  The Vikings would respond with RB Chester Taylor's 1-yard TD run.  In the second quarter, Cards kicker Neil Rackers gave Arizona a 21-yard and a 50-yard field goal for a decent lead.  However, the Vikes took the lead with QB Brad Johnson's 17-yard TD pass to WR Marcus Robinson.  In the third quarter, more of the Cardinals' year-long ineffectiveness showed as Johnson completed a 9-yard TD pass to WR Billy McMullen, while kicker Ryan Longwell nailed a 40-yard field goal.  In the fourth quarter, Minnesota improved its lead on Johnson's 3-yard TD pass to FB Jeff Dugan.  Afterwards, Arizona tried to fight back as Strong Safety Adrian Wilson returned a fumble 99 yards for a touchdown, yet it was followed up by a failed two-point conversion.  Afterwards, QB Matt Leinart completed a 9-yard TD pass to WR Anquan Boldin.  Afterwards, the Vikings wrapped up the game and won.  With the loss, the Cardinals fell to 2-9.

A: How many field goals measured between 40 yards and 50 yards long?

Q: Passage: The Easter Rising lasted from Easter Monday 24 April 1916 to Easter Saturday 29 April 1916. Annual commemorations, rather than taking place on 24-29 April, are typically based on the date of Easter, which is a moveable feast. For example, the annual military parade is on Easter Sunday; the date of coming into force of  the Republic of Ireland Act 1948 was symbolically chosen as Easter Monday  1949. The official programme of centenary events in 2016 climaxed from 25 March  to 2 April  with other events earlier and later in the year taking place on the calendrical anniversaries.

A: How many days did the Easter Rising last for?

Q: Passage: African elephants were listed as Vulnerable species by the International Union for Conservation of Nature (IUCN) in 2008, with no independent assessment of the conservation status of the two forms. In 1979, Africa had an estimated minimum population of 1.3 million elephants, with a possible upper limit of 3.0 million. By 1989, the population was estimated to be 609,000; with 277,000 in Central Africa, 110,000 in East Africa, 204,000 in southern Africa, and 19,000 in West Africa. About 214,000 elephants were estimated to live in the rainforests, fewer than had previously been thought. From 1977 to 1989, elephant populations declined by 74% in East Africa. After 1987, losses in elephant numbers accelerated, and savannah populations from Cameroon to Somalia experienced a decline of 80%. African forest elephants had a total loss of 43%. Population trends in southern Africa were mixed, with anecdotal reports of losses in Zambia, Mozambique and Angola while populations grew in Botswana and Zimbabwe and were stable in South Africa. Conversely, studies in 2005 and 2007 found populations in eastern and southern Africa were increasing by an average annual rate of 4.0%. Due to the vast areas involved, assessing the total African elephant population remains difficult and involves an element of guesswork. The IUCN estimates a total of around 440,000 individuals for 2012.

A:
How many is the difference between the upper limit of elephants in Africa and the minimum?
