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.

Example Input: Passage: However, this was due to the influx of approximately 200,000 Crimean Tatars &ndash; a number equivalent to approximately 10% of Crimeas 1989 population – who arrived in Crimea after 1989 and whose population in that region increased by a factor of 6.4 from 38,000 to 243,400 between 1989 and 2001. Collectively, the net population loss in the regions of Ukraine outside the westernmost regions was 2,759,200 people or 6.6% of the 1989 population. The total population of these regions in 2001 was 39,186,100.
Example Output: How many Crimean Tatars did the population increase by between 1989 and 2001?

Example Input: Passage: His first taste of land battle in Russia was the disastrous defeat at Narva, in which Lacy commanded a unit of musketeers, holding the rank of poruchik. During the Great Northern War he was seriously wounded on two occasions, gaining the rank of colonel in 1706. The following year he led a brigade at Poltava, in which battle he greatly distinguished himself. From this point began his fame as a soldier. His next active service, still under Prince Repnin, was the siege of Riga. Lacy was reputedly the first Russian officer to enter the capital of Livland and he was appointed the first Russian chatelain of Riga Castle in the aftermath. In 1719 Apraksin's fleet landed Lacy with 5,000 infantry and 370 cavalry near Umeå in Sweden, where they proceeded to devastate a dozen iron foundries and a number of mills. Soon promoted general, he entered the Military Collegium  — as the Russian Ministry of Defense was then known - in 1723. Three years later, Lacy succeeded Repnin in command of the Russian forces quartered in Livland, and in 1729 he was appointed Governor of Riga. These positions brought him in contact with the Duchess of Courland, who before long ascended the Russian throne as Empress Anna. During her reign, Lacy's capacity for supreme command would never be doubted.
Example Output: After Umeå, what rank was Lacy promoted to?

Example Input: Passage: Still trying to get their first win, the Dolphins flew to Wembley Stadium for their special international interconference game against the New York Giants.  For the game, Miami was listed as the home team.  In the first quarter, the Dolphins trailed early as Giants kicker Lawrence Tynes nailed a 20-yard field goal for the only score of the period.  In the second quarter, Miami's struggles continued with N.Y. QB Eli Manning getting a 10-yard TD run, along with Tynes nailing a 41-yard field goal. In the third quarter, the 'Fins started to make a comeback as former Giants kicker Jay Feely got a 29-yard field goal for the only score of the period.  In the fourth quarter, Miami drew close as QB Cleo Lemon completing a 21-yard TD pass to rookie WR Ted Ginn, Jr.  However, New York managed to hold on to their lead for the win. With their 11th-straight loss, the Dolphins entered their bye week at 0-8.
