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."

[EX Q]: Background Paragraph: Making these healthy lifestyle choices can also help prevent some types of cancer. In addition, you can lower the risk of cancer by avoiding carcinogens , which are substances that cause cancer. For example, you can reduce your risk of lung cancer by not smoking. You can reduce your risk of skin cancer by using sunscreen. How to choose a sunscreen that offers the most protection is explained below ( Figure below ). Some people think that tanning beds are a safe way to get a tan. This is a myth. Tanning beds expose the skin to UV radiation. Any exposure to UV radiation increases the risk of skin cancer. It doesn't matter whether the radiation comes from tanning lamps or the sun.
Story: Paul started a healthy lifestyle because he wanted to avoid getting cancer. His cousin Pete laughed at him, and continued eating fast-foods, smoking and disregarding his health completely.
[EX A]: Which cousin continued using tanning beds?

[EX Q]: Background Paragraph: Another possible benefit of aggregation is to protect against predation by group anti-predator behavior. Many species exhibit higher rates of predator vigilance behavior per individual at lower density. This increased vigilance might result in less time and energy spent on foraging, thus reducing the fitness of an individual living in smaller groups. One striking example of such shared vigilance is exhibited by meerkats. Meanwhile, other species move in synchrony to confuse and avoid predators such as schools of sardines and flocks of starlings. The confusion effect that this herding behavior would have on predators will be more effective when more individuals are present.Cooperative feeding.
Story: In the sub-Saharan African country of Nigeria, there are two main species that tend to travel in groups. The antelope tend to travel in groups in high numbers, and thus exhibit a high density. Meanwhile, the bison tend to travel in groups of small numbers, and therefore exhibit low density. Both the antelope and the bison have natural predators that exist in Nigeria.
[EX A]: Individuals from which species, the antelope or the bison, will have higher rates of predator vigilance behavior?

[EX Q]: 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: Bradly had a busy day storing XML. At 6 AM, he stored 200 Gigabytes to the database. At 7 AM, he stored 300 Gigabytes to the database. At 8 AM, he stored 400 Gigabytes to the database. At 9 AM, he got breakfast. At 10 AM, he stored 500 Gigabytes to the database. At 11 AM, he stored 600 Gigabytes to the database. At 12 PM, she went to sleep to finish storing XML later.
[EX A]:
What time did storage costs go up: 10 AM or 12 PM?
