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.

Passage: On 2 May, 1687, a Russian army of about 132,000 soldiers, led by knyaz Vasily Golitsyn, left Okhtyrka on the Belgorod Line. On 30 May they were joined by 50,000 Left Bank Cossacks under hetman Ivan Samoilovich at the mouth of the Samora River where the Dnieper turns south. In the heat of summer, 180,000 men, 20,000 wagons and 100,000 horses set out down the east bank of the Dnieper. The huge force, which started too late and was perhaps not well organized, could only travel about 10km per day. When the Russians reached the Konskiye Vody river on the west-flowing part of the Dnieper, they found that the Tatars has set fire to the steppe . After a few days of marching over burnt land, their horses were exhausted, they were short of water and 130 miles from their goal at Perekop, however Golitsyn built a fortress at Novobogoroditskoe at the junction of the Dnieper and the Samara. On 17 June they decided to turn back.
answer:
