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: The Lines of Communication were English Civil War fortifications commissioned by Parliament  and built around London between 1642 and 1643 to protect the capital from attack by the Royalist armies of Charles I. In 1642 some basic fortifications were built, in the form of street barricades and small earthworks. In 1643 a major construction effort was made, to provide a comprehensive ring of fortifications around the city. Much of the work was done by volunteer labour, organized by the trained bands and the livery companies. Up to 20,000 people are thought to be involved, and the works were completed in under two months. The fortifications failed their only test when the New Model Army entered London in 1647, and they were levelled by Parliament the same year.
[EX A]: How many months did it take them to build The Lines of Communication?

[EX Q]: Passage: Coming off their dominating home win over the Chiefs, the Broncos flew to Reliant Stadium for a Thursday night intraconference duel with the Houston Texans.  In the first quarter, Denver trailed early as QB Sage Rosenfels got a 5-yard TD run for the only score of the period.  In the second quarter, the Broncos would get on the board as kicker Jason Elam managed to get a 41-yard field goal.  Houston would respond with kicker Kris Brown getting a 41-yard field goal.  Denver would end the half with Elam nailing a 47-yard field goal. In the third quarter, the Texans would increase their lead as RB Ron Dayne managed to get a 6-yard TD run.  The Broncos would respond with QB Jay Cutler completing a 12-yard TD pass to TE Tony Scheffler.  However, in the fourth quarter, Houston sealed the win as Rosenfels completed a 4-yard TD pass to WR Andre Johnson, while FB Vonta Leach got a 1-yard TD run.
[EX A]: How many field goals did Elam kick?

[EX Q]: Passage: On June 1, 1922, in Helsinki, Finland and Soviet Russia signed an Agreement between RSFSR and Finland about the measures providing the inviolability of the Soviet-Finnish border. Both parties agreed to reduce the number of border guards and to keep those who do not reside permanently in the border zone from freely crossing the border from either side to the other. Towards the end of the uprising some 30 000 East Karelian refugees evacuated to Finland. The Karelian Worker's Commune was renamed into the Karelian Autonomous Soviet Socialist Republic in 1923, and its autonomy was further expanded. However the cultural autonomy practically ended in 1933 - 1935 when the émigré Finnish leaders Edvard Gylling and Kustaa Rovio were purged and teaching of Finnish language was prohibited.  Gylling had promoted the adoption of Finnish rather than Karelian within the KASSR as he and the other émigré Finns who dominated the leadership of Karelia prior to 1935 did not consider Karelian to be anything more than a rustic dialect of Finnish.  It may also be argued they held the same view of the essential unity of the Karelians and Finns as one Finnic people as their nationalist counterparts, and also wished that they be unified .
