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: The example of someone having a positive experience with a drug is easy to see how drug dependence and the law of effect works. The tolerance for a drug goes up as one continues to use it after having a positive experience with a certain amount the first time.[38] It will take more and more to get that same feeling. This is when the controlled substance in an experiment would have to be modified and the experiment would really begin. The law of work for psychologist B. F. Skinner almost half a century later on the principles of operant conditioning, "a learning process by which the effect, or consequence, of a response influences the future rate of production of that response.[39]. 
Story: The Blow Brigade met to discuss their experiences. They all said they always had a great experience using blow and used the same amount each time. They told how many times they used blow. Gloria used it 20 times, Evelyn used it 25 times, Jean used it 37 times, Cheryl used it 48 times, Mildred used it 56 times, Katherine used it 64 times, and Joan used it 70 times.
[EX A]: Who has a higher tolerance for blow: Cheryl or Joan?

[EX Q]: Background Paragraph: The Mercator projection is best within 15 degrees north or south of the equator. Landmasses or countries outside that zone get stretched out of shape. The further the feature is from the equator, the more out of shape it is stretched. For example, if you look at Greenland on a globe, you see it is a relatively small country near the North Pole. Yet, on a Mercator projection, Greenland looks almost as big the United States. Because Greenland is closer to the pole, the continent's shape and size are greatly increased. The United States is closer to its true dimensions. 
Story: Stef is a young girl interested in the geography of the world. For her birthday, she got two different representations of the Earth. Her grandparents gave her a map that uses the Mercator projection and her uncle gave her a globe. She is comparing how certain countries look differently on the two gifts and trying to figure out why that is. She is specifically looking at Norway, a country near the North Pole, and Mexico, a country close to the equator.
[EX A]: On which representation of Earth will Norway look bigger?

[EX Q]: Background Paragraph: Some processes in the body are regulated by positive feedback. Positive feedback is when a response to an event increases the likelihood of the event to continue. An example of positive feedback is milk production in nursing mothers. As the baby drinks her mother's milk, the hormone prolactin, a chemical signal, is released. The more the baby suckles, the more prolactin is released, which causes more milk to be produced. Other examples of positive feedback include contractions during childbirth. When constrictions in the uterus push a baby into the birth canal, additional contractions occur. 
Story: John is a doctor at the children's hospital. He had two different cases to investigate, case A and case B. In case case A, a baby continued to suckle mother's milk. But in case B, a baby stopped suckling mother's milk. He had to determine the different effects these two cases were causing.
[EX A]:
In case A would less or more milk be produced than in case B?
