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.

[Q]: Passage: Crimean Khan Haji Giray, learning of the defeat of the Budjak Tatars gathered 10,000-12,000 men and went against Kunitsky. At the end of December Kunitsky with 10,000-12,000 Cossacks and Moldavians left Budjak and began to cross the Prut River near the village of Tobak, not far from the town of Reni, Ukraine. Here on 30 December they were suddenly attacked by Tatar cavalry under Khan Haji Giray. Kunitsky built a fortified camp and successfully repelled the Tatar attacks. On the night of 3 to 4 January 1684 the Moldavian allies betrayed the Cossacks and left the Cossack camp. In this situation Kunitsky with the Cossack cavalry  broke through the enemy ring and crossed the Prut. The Cossack infantry  under Andrey Mogila also broke out and crossed the Prut near Boyanova, but suffered heavy losses. By 10 January only five thousand Cossacks reached Jassy.
[A]: How many days after the Cossacks and Moldavians were attacked by Tatar calalry under Khan Haji Giray did the Moldavian allies betray the Cossacks?


[Q]: Passage: The kingdoms of France and Scotland had traditionally enjoyed a close diplomatic relationship, reflected in a defensive treaty signed between the two kingdoms in 1512. When Henry crossed the English Channel to campaign in France, the King of France activated the treaty, sending arms, money and military advisers to James IV of Scotland to encourage him to fulfil his obligations, in the hope that this would draw English resources away from the invasion of France. James crossed the border with a force of some 35,000 men, including 5,000 French advisers. He was opposed by an English force under the Earl of Surrey. The two sides met on September 9, 1513, near the village of Flodden. The Scottish army was heavily defeated, losing some 9,000 men and many nobles, including King James, the King's illegitimate son, and twelve earls.
[A]: Did the kingdoms of France and Scotland have a treaty?


[Q]: Passage: The Dolphins began the 2003 season with a 21-20 loss to the 2003 Houston Texans season, but they rebounded to win four straight games. During a crushing overtime loss at the hands of the 2003 New England Patriots season, Jay Fiedler was injured, forcing newly acquired backup Brian Griese to lead the Dolphins to victory the next week over San Diego. That, however, was Grieses high point, and after a good showing against 2003 Indianapolis Colts season in a losing effort (he threw for 231 yards and a touchdown in the 23-17 Colts win), he struggled against the 2003 Tennessee Titans season, throwing three interceptions in a 31-7 Tennessee win, and was highly ineffective against the 2003 Baltimore Ravens season, managing just 126 yards in a 9-6 overtime win. The Dolphins fell behind to the 2003 Washington Redskins season after Griese threw two interceptions; trailing 20-7, Fiedler came off the bench and led a comeback victory, 24-23. Miami looked like it might rebound thanks to a 40-21 NFL on Thanksgiving Day victory over the 2003 Dallas Cowboys season that took them to 8-4, but two key losses to the 2003 New England Patriots season and the 2003 Philadelphia Eagles season ended Miamis postseason hopes. Miami finished 10-6 after victories over Buffalo and the Jets.
[A]:
Who did Brian Griese replace?
