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: Porfirio had a busy day storing XML. At 9 AM, he stored 203 Gigabytes to the database. At 10 AM, he stored 303 Gigabytes to the database. At 11 AM, he stored 403 Gigabytes to the database. At 12 PM, he got lunch. At 1 PM, he stored 503 Gigabytes to the database. At 2 PM, he stored 603 Gigabytes to the database. At 3 PM, she went to sleep to finish storing XML later that night.

SOLUTION: What time did storage costs go up:  1 PM or 12 PM?

PROBLEM: Background Paragraph: The "concentration" of a solid is essentially another way of measuring its density. A certain number of moles are present for a given volume of the solid, and this value does not depend on how much of the solid is present. As the reaction proceeds, the amount of solid reactant will decrease, but so will the volume it occupies. A similar argument can be made for liquids. As a result, the concentrations of solids and liquids are essentially constant over the course of a reaction. 
Story: Cindy has a ball of iron. She measures its density then drops it in a vat of hydrochloric acid. Ashe then removes the irom from the acid noting that the acid ate away as a good potion of the iron. To her suprise however the density of the iron remained constant.

SOLUTION: Given cindy drops an ice cube in warm water then removes it, will the density of the remaining ice change or remain constant.?

PROBLEM: Background Paragraph: Generally speaking, more mafic magmas, such as those that form basalt, are hotter and less viscous than more silica-rich magmas, such as those that form rhyolite. Low viscosity leads to gentler, less explosive eruptions. 
Story: John visited Sicily to see Mount Etna eruption. He noticed that magma there formed rhyolite. He was so excited to an eruption that when next time Kilauea eruption started in Hawaii, he went to see that. He found that unlike Etna Kilauea eruption formed basalt.

SOLUTION:
Which eruption would be less explosive, Etna or Kilauea?
