instruction:
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.
question:
Passage: The Turkish-Armenian war, known in Turkey as the Eastern Operation or Eastern Front  of the Turkish War of Independence, refers to a conflict in the autumn of 1920 between the First Republic of Armenia and the Turkish nationalists, following the signing of the Treaty of Sèvres. After an initial Armenian occupation of what is now eastern Turkey, the army of the Turkish National Movement under Kâzım Karabekir reversed the Armenian gains and further invaded and defeated Armenia, also recapturing territory which the Ottoman Empire had lost to the Russian Empire in 1855 and 1878. The Turkish military victory was followed by Soviet Russia's occupation and sovietization of Armenia. The Treaty of Moscow  between Soviet Russia and the Grand National Assembly of Turkey and the related Treaty of Kars  confirmed the territorial gains made by Karabekir and established the modern Turkish-Armenian border. Armenia had territorial disputes with the Ottoman Empire. The Ottomans had tried to move the Armenians during the Armenian Genocide and occupied the South Caucasus during Summer 1918. Armenia resisted until the Allied forces won WWI. The Ottomans maintained their troops along their territorial gains until Spring 1919.
answer:
For what time span was the Ottoman Empire able to maintain the territorial gains they won from Armenia?


question:
Passage: Coming off their third straight loss, Washington traveled to Oakland to play the Oakland Raiders for the first time since 2009. Washington got the ball to start the game, and punted. Oakland then followed with a punt, too. Washington went three-and-out yet again, but this time, Saverio Rocca's punt was blocked by Raiders running back Rashad Jennings and recovered by fellow Raiders running back Jeremy Stewart in the end zone for a Raiders touchdown and a 7-0 lead. Washington could not respond, and when Oakland got the ball again, quarterback Matt Flynn, filling in for concussed quarterback Terrelle Pryor found rookie tight end Mychal Rivera (brother of Glee star Naya Rivera) for a 31-yard score and a 14-0 Raiders lead. Needing a spark, Washington switched to a hurry-up offense for their next drive, and sustained one for the first time on the day. It stalled when it reached the red zone, however, and Washington placekicker John Potter hit a 25-yard chip shot to cut the deficit to 14-3. Later in the quarter, Matt Flynn threw a pass that was intercepted by cornerback David Amerson and returned 45 yards for a score and the deficit was 14-10. The teams were not able to do much else, and the halves concluded with this score at 14-10. In the third, both offenses continued to struggle, but late in the third, Washington quarterback Robert Griffin III found wide receiver Pierre Gar&#231;on for a 5-yard score, and Washington's first lead in the second half of a game all season. In the fourth, Oakland's offense continued to sputter, even fumbling for a second time at midfield. Washington was able to sustain a running game in spite of an injury to star running back Alfred Morris, with typical third-down back Roy Helu, Jr. running into the end zone from 14 yards out to increase Washington's lead to 24-14. Oakland could not rally, and Washington held on for its first win. With the win, Washington improved to 1-3 and heads into the bye week, reconvening on NBC Sunday Night Football for a clash with Dallas in two weeks. This was Washington's third consecutive win against an AFC opponent.
answer:
How long was Flynn's touchdown pass?


question:
Passage: International tourist arrivals reached 1.035 billion in 2012, up from over 996 million in 2011, and 952 million in 2010. In 2011 and 2012, international Travel behavior continued to recover from the losses resulting from the late-2000s recession, where tourism suffered a strong slowdown from the second half of 2008 through the end of 2009. After a 5% increase in the first half of 2008, growth in international tourist arrivals moved into negative territory in the second half of 2008, and ended up only 2% for the year, compared to a 7% increase in 2007. The negative trend intensified during 2009, exacerbated in some countries due to the outbreak of the 2009 flu pandemic, resulting in a worldwide decline of 4.2% in 2009 to 880 million international tourists arrivals, and a 5.7% decline in international tourism receipts.
answer:

How many million fewer international tourist arrivals were there in 2009 than in 2010?
