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: The Vikings' second preseason game took them to San Francisco to take on the 49ers. The game marked the return of quarterback Brett Favre to the Vikings' starting lineup, but he lasted just four plays; the first was a 13-yard pass to RB Adrian Peterson for a first down, but he was sacked for a loss of 10 yards two plays later and was replaced by Tarvaris Jackson for the Vikings' next drive. By the time Favre took the field, the 49ers were already leading 7-0 via a 4-yard run from Anthony Dixon. It was not until the 2nd quarter that the Vikings got their first points on the board, with Ryan Longwell landing a 40-yard field goal. San Francisco responded with two Joe Nedney field goals in the second half before the Vikings' rookie QB Joe Webb took advantage of a gap in the 49ers defense to rush 48 yards for a touchdown, bringing Minnesota within three points with two minutes left to play. Kicker Rhys Lloyd attempted an onside kick, but it was recovered by San Francisco, and by the time the Vikings got the ball back they were on their own 8-yard line with 9 seconds left in the game. They attempted to go for the win, but Webb was sacked in the end zone for a safety as the clock ran out, giving the 49ers a 15-10 win.
[EX A]: How many field goals were made?

[EX Q]: Passage: Baldwin de Burg was a nephew of Baldwin I of Jerusalem and the Count of Edessa from 1100 to 1118. In 1118 his uncle died and he became King Baldwin II of Jerusalem. In the Battle of Ager Sanguinis, fought near Sarmada on 28 June 1119, the Franks suffered a disastrous defeat by the forces of Ilghazi, the ruler of Mardin. Later that year Baldwin regained some territory, but the Franks were seriously weakened. Baldwin asked for help from Pope Callixtus II. The pope forwarded the request to Venice. The terms of the crusade were agreed through negotiations between the envoys of Baldwin II and the doge of Venice. Once the Venetians decided to participate, Pope Callixtus II sent them his papal banner to signify his approval, At the First Council of the Lateran he confirmed that the Venetions had crusader privileges, including remission of their sins. The church also extended its protection to the families and property of the crusaders. In 1122 the Doge of Venice, Domenico Michiel, launched the seaborne crusade. The Venetian fleet of more than 120 ships carrying over 15,000 men left the Venetian Lagoon on 8 August 1122. This seems to have been the first crusade in which the knights brought their horses with them. They invested Corfu, then a possession of the Byzantine Empire, with which Venice had a dispute over privileges. In 1123 Baldwin II was captured by Balak of Mardin, emir of Aleppo, and imprisoned in Kharput. Eustace Graverius became regent of Jerusalem. The Venetians abandoned the siege of Corfu when they heard this news, and reached the Palestinian coast in May 1123.
