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: In the first period, before 1648, we are dealing mostly with raids and defensive measures. Before 1507 raids were into the Polish Ukraine extending as far as Belarus. After 1507 raiding into the Ukraine continued but most raids were in the region south of Moscow. There was a tendency for population, fortifications and raiding to shift south from Moscow and east from the Polish/Ukrainian area. After 1648 we are dealing with large armies - Tatars, Turks, Poles, Russians and large numbers of Ukrainian Cossacks. Most fighting was in the western Ukraine . This drove the Slavic population to the Left Bank and probably allowed Russian population to expand southward north of Ukraine. Fighting weakened the Polish Commonwealth, but Russia continued to grow southward until it annexed Crimea in 1783. Note that this list does not include raids before 1480, raids further east, most Cossack raids on Crimea and petty raiding between different groups of Nogais, which was considerable. The main underlying theme of the period is the southward expansion of Russian population and the eastward expansion of Ukrainian population. If we had population figures for this the history of the period would be much clearer.
[EX A]: How many years after raids were well into the Polish Ukraine as far as Belarus did Russia annex Crimea?

[EX Q]: Passage: At the end of March  Nakaznoy Hetman Ostap Gogol with the Podolian Regiment and some Budjak Tatars invaded the Letichevsky Powiat of the Podolian Voyevodstvo. Cossack-Tatar troops looted and burned the neighborhood of Bar, Medzebozh, Derazhnya, Old and New Senyavy, Zinkov and Gusyatin. On 20 July Doroshenko resumed the siege of the Polish garrison at Bila Tserkva and sent his younger brother Gregory and 2,000 Cossacks to Podolia. He sent the Kalnitsky regiment to Crimea to help Adil Giray against Zaporozhians. Doroshenko, with no more than 5,000-8,000 Cossacks  and 5,000-6,000 Tatar allies did not dare to go to war, but awaited Adil Giray before starting an offensive against Commonwealth. Most of the Budjak Mirzas who were with Gregory Doroshenko, on learning of the approach of the Polish militia, hastily left their ally and returned to their camps. Grand Crown Hetman Jan Sobieski advanced against Doroshenko and the Crimean horde. On 26 August at Bratslav the Polish army routed the Cossack and Tartar troops. The Poles defeated the Budjak Tatars and burst into Bratslav. The Cossacks took refuge in the city castle and the broken Tatars began to retreat in panic. Sobieski led cavalry in pursuit of the Tatars while some Poles stayed in Bratslav to besiege the castle. The Poles followed the Tatars to Batorg and completely defeated them. The Cossacks in the castle learned of the defeat of the Tatars and surrendered. Emir Ali, who commanded the Budjak troops said he lost 500 men. Despite the victory, Sobieski withdrew to Bar, where he arrived on 30 August.
[EX A]: At the end of March, how many locations did Cossack-Tatar troops loot and burn?
