TASK DEFINITION: You are given a background paragraph that describes one or more causal or qualitative relationships such as a relationship in economics or a scientific law and a story that makes use of the concepts or the relationship described in the provided paragraph. You need to come up with a question about the story that requires an understanding of the relationship described in the background paragraph. The generated question should not be answerable without both the background and story. Write a question about the story that requires a relationship in the background paragraph to answer. Check whether your question requires both the background paragraph and the story to answer. If your question can be answered by only one of these, try to rewrite your question so that it requires both. Note that "flipping" a word in the question can give rise to a new question where the answer will be different from the original question. Often, "flipping" a word gives rise to flipping the direction of the relationship, for example, from "increase" to "decrease."
PROBLEM: Background Paragraph: Storing large volumes of data – When storing XML to either file or database, the volume of data a system produces can often exceed reasonable limits, with a number of detriments: the access times go up as more data is read, CPU load goes up as XML data takes more power to process, and storage costs go up. By storing XML data in Fast Infoset format, data volume may be reduced by as much as 80 percent. 
Story: Gary had a lot of storing to do on his computer. At 1 PM, he stored 1 Gigabyte of XML data to the main file. At 2 PM, he stored 2 Gigabytes of XML data to the main file. At 3 PM, he didn't store anything. At 4 PM, he stored 3 Gigabytes of XML data to the main file. At 5 PM, he stored 4 Gigabytes of XML data to the main file. At 6 PM, he did nothing. At 7 PM, he got dinner. At 8 PM, he stored 5 Gigabytes of XML data to the main file.

SOLUTION: What hour did storage costs go up: 1 PM or 3 PM?

PROBLEM: Background Paragraph: Regions on the Earth's surface (or in its atmosphere) that are high above mean sea level are referred to as high altitude. High altitude is sometimes defined to begin at 2,400 meters (8,000 ft) above sea level.[5][6][7]

At high altitude, atmospheric pressure is lower than that at sea level. This is due to two competing physical effects: gravity, which causes the air to be as close as possible to the ground; and the heat content of the air, which causes the molecules to bounce off each other and expand.[8]. 
Story: There was a competition for who can get the kite highest into the air. Team A got it 2,000 ft. Team B got it 3,000 ft. Team C go it 6,000 ft. Team D got it 9,000 ft. Team E got it 10,000 ft.  Team F got it 11,000 ft. Team G got it 12,000 ft. Team G won the contest and got a gold trophy as the prize.

SOLUTION: What team got their kite into high altitude: Team A or Team D?

PROBLEM: Background Paragraph: An anaerobic organism is any organism that does not need oxygen for growth and even dies in its presence. Obligate anaerobes will die when exposed to atmospheric levels of oxygen. Clostridium perfringens bacteria, which are commonly found in soil around the world, are obligate anaerobes. Infection of a wound by C. perfringens bacteria causes the disease gas gangrene. Obligate anaerobes use molecules other than oxygen as terminal electron acceptors. 
Story: Microbiologist John is studying the anaerobic organism. He collected two samples of this organism, sample A and sample B. Sample A is an anaerobic organism, and sample B is specifically identified as the Clostridium perfringens obligate anaerobe. To compare these samples to other organisms he collected another microbe that is not an anaerobic organism. He labeled it as sample C.

SOLUTION:
Which sample might die in presence of oxygen, sample A or sample C?
