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: 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.

SOLUTION: For what time span was the Ottoman Empire able to maintain the territorial gains they won from Armenia?

PROBLEM: Passage: From the Act of Union on 1 January 1801, until 6 December 1922, the island of Ireland was part of the United Kingdom of Great Britain and Ireland. During the Great Famine, from 1845 to 1849, the island's population of over 8 million fell by 30%. One million Irish died of starvation and/or disease and another 1.5 million emigrated, mostly to the United States. This set the pattern of emigration for the century to come, resulting in a constant population decline up to the 1960s.

SOLUTION: After the Great Famine, Ireland's population was approximately how many people?

PROBLEM: Passage: From 1989 to 1990, the Najibullah government was partially successful in building up the Afghan defence forces. The Khad had established a local militia force which stood at an estimated 100,000 men. The 17th Division in Herat, which had begun the 1979 Herat uprising against PDPA-rule, stood at 3,400 regular troops and 14,000 tribal men. In 1988, the total number of security forces available to the government stood at 300,000. This trend did not continue, and by the summer of 1990, the Afghan government forces were on the defensive again. By the beginning of 1991, the government controlled only 10 percent of Afghanistan, the eleven-year Siege of Khost had ended in a mujahideen victory and the morale of the Afghan military finally collapsed. In the Soviet Union, Kryuchkov and Shevardnadze had both supported continuing aid to the Najibullah government, but Kryuchkov had been arrested following the failed 1991 Soviet coup détat attempt and Shevardnadze had resigned from his posts in the Soviet government in December 1990 - there were no longer any pro-Najibullah people in the Soviet leadership and the Soviet Union was in the middle of an economic and political crisis, which would lead directly to the dissolution of the Soviet Union on 26 December 1991. At the same time Boris Yeltsin became Russias new hope, and he had no wish to continue to aid Najibullahs government, which he considered a relic of the past. In the autumn of 1991, Najibullah wrote to Shevardnadze "I didnt want to be president, you talked me into it, insisted on it, and promised support. Now you are throwing me and the Republic of Afghanistan to its fate.".

SOLUTION:
How many more tribal men than regular troops were in the 17th Division in Herat?
