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: In September and October 1868, two notable actions happened with Troops H & I under the command of Brevet Lieutenant Colonel  Louis H. Carpenter. The first was the rescue of Lieutenant Colonel G. A. Forsyth whose small party of 48 white scouts, was attacked and "corralled" by a force of about 700 Native American Indians on a sand island up the North Fork of the Republican River; this action became the Battle of Beecher Island. The second was two weeks after Carpenter had returned to Fort Wallace with the survivors of Forsyth's command. Troops H and I of the 10th Cavalry sallied forth for an escort and supply to the 5th Cavalry near Beaver Creek. Near there Carpenter combined command was attacked by a force of about 500 Indians. After a running fight and defensible stand the "hostiles" retreated. Carpenter would later receive the Medal of Honor for these two actions. For the next eight years, the 10th was stationed at numerous forts throughout Kansas and Indian Territory , including Fort Gibson starting in 1872. They provided guards for workers of the Kansas and Pacific Railroad, strung miles of new telegraph lines, and to a large extent built Fort Sill. Throughout this period, they were constantly patrolling the reservations and engaging "hostiles" in an attempt to prevent Indian raids into Texas.
[EX A]: How many days were in between the two attacks?

Gentoo was placed 18th in 2010, 20th in 2011, 22nd in 2012, 33rd in 2013, 38th in 2014, and 45th in 2015. In 2016 it became slightly more popular, climbing back up to 35th place, but has since fallen to 41st (averaged out over the last three months).
[EX A]:
How many positions did Gentoo drop between 2004 and 2007?
