Instructions: 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.
Input: Passage: Prior to kickoff, the game was delayed due to the turf being caught on fire, coming from the fireworks. The Rams struggled offensively and defensively all game long.  The defense, for the most part, sacked Ben Roethlisberger until he left the game with an apparent knee injury. Michael Vick took over for the rest of the game. Late in the fourth quarter Kenny Britt's catch was overturned. The Steelers would go on to stun the Rams, 12-6.
Output:
Which of them had a positive upset?
