TASK DEFINITION: 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.
PROBLEM: Passage: According to the Stockholm International Peace Research Institute, between 2005-2009 and 2010-2014, Russian exports of major weapons increased by 37 percent; Russia spent $66.4 billion on arms in 2015, then $69.2 billion in 2016, having taken 3rd place (after the U.S. and China).  According to the Russian Defence Ministry, share of modern weapons in the Armed Forces reached from 26 to 48 percent among different kinds of troops in December 2014. This was raised to 30.5–70.7% as of July 2015. The average was 58 per cent over the first half of 2017.

SOLUTION: Did the share of modern weapons in the Armed Forces increase or decrease between 2014 and 2015?

PROBLEM: Passage: The Saints began their season with a Week 1 duel with the Detroit Lions. New Orleans would get off to a fast start in the first quarter as quarterback Drew Brees completed a 9-yard touchdown pass to wide receiver Marques Colston and a 39-yard touchdown pass to wide receiver Robert Meachem. The Lions would answer with kicker Jason Hanson getting a 47-yard field goal. In the second quarter, Detroit came closer as running back Kevin Smith got a 4-yard touchdown run. The Saints would reply with Brees completing a 1-yard and a 15-yard touchdown pass to tight end Jeremy Shockey. The Lions tried to catch up in the third quarter as quarterback Matthew Stafford got a 1-yard touchdown run, yet New Orleans answered with kicker John Carney making a 39-yard field goal. Detroit would respond with Hanson nailing a 24-yard field goal, while the Saints kept pounding away as Brees completed a 58-yard touchdown pass to wide receiver Devery Henderson. The Lions would close out the period with safety Louis Delmas returning a fumble 65 yards for a touchdown. In the fourth quarter, New Orleans closed out the game as Brees completed a 13-yard touchdown pass to fullback Heath Evans. With the win, not only did the Saints begin their season at 1-0, but Brees (26-of-34, 358 yards, 6 TDs, 1 INT) became the very first quarterback to throw 6 TD passes in an opening day game, as well as tying Billy Kilmer's franchise record for touchdown passes in a game.

SOLUTION: How long was the longest touchdown?

PROBLEM: Passage: From 1789 to 1815, members of Congress received only a daily payment of $6 while in session. Members received an annual salary of $1,500 per year from 1815 to 1817, then a per diem salary of $8 from 1818 to 1855; since then they have received an annual salary, first pegged in 1855 at $3,000. In 1907, salaries were raised to $7,500 per year, the equivalent of $173,000 in 2010. In 2006, members of Congress received a yearly salary of $165,200. Congressional leaders were paid $183,500 per year. The Speaker of the House of Representatives earns $212,100 annually. The salary of the President pro tempore of the United States Senate for 2006 was $183,500, equal to that of the Party leaders of the United States House of Representatives and Party leaders of the United States Senate. Privileges include having an office and paid staff. In 2008, non-officer members of Congress earned $169,300 annually. Some critics complain congressional pay is high compared with a median American Household income in the United States of $45,113 for men and $35,102 for women. Others have countered that congressional pay is consistent with other branches of government. Another criticism is that members of Congress have access to free or low-cost medical care in the Washington D.C. area.  The petition, "Remove health-care subsidies for Members of Congress and their families", has already gathered over 1,076,000 signatures on the website Change.org.  In January 2014, it was reported that for the first time over half of the members of Congress were millionaires. Congress has been criticized for trying to conceal pay raises by slipping them into a large bill at the last minute. Others have criticized the wealth of members of Congress. Representative Jim Cooper of Tennessee told Harvard professor Lawrence Lessig that a chief problem with Congress was that members focused on lucrative careers as lobbyists after serving––that Congress was a "Farm team for K Street (Washington, D.C.)"––instead of on public service.

SOLUTION:
By how many dollars did a Congressman's annual salary increase between 1855 and 1907?
