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: For their annual Thanksgiving Day game, the Lions hosted a rematch with their divisional rival, the Minnesota Vikings. The Vikings scored 13 points in the first quarter via a one-yard touchdown pass from Case Keenum to Kyle Rudolph, and a nine-yard touchdown run from Keenum. The Lions responded with 10 points in the second quarter via a 32-yard field goal from Matt Prater and a six-yard touchdown pass from Matthew Stafford to Marvin Jones Jr. The Vikings extended their lead in the second quarter via a 22-yard touchdown pass from Keenum to Rudolph to make the score 20-10 in favor of Minnesota at half-time. The Vikings opened the scoring in the second half via a two-yard touchdown run from Latavius Murray.

The Lions reduced the Vikings lead to four points in the fourth via a 43-yard touchdown pass from Stafford to Jones. The Vikings extended their lead in the fourth quarter via a 36-yard field goal from Kai Forbath.
