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: One reason radiation is dangerous is that it can’t be detected with the senses. You normally can’t see it, smell it, hear it, or feel it. Fortunately, there are devices such as Geiger counters that can detect radiation. A Geiger counter, like the one in Figure below , has a tube that contains atoms of a gas. If radiation enters the tube, it turns gas atoms to ions that carry electric current. The current causes the Geiger counter to click. The faster the clicks occur, the higher the level of radiation. 
Story: Andre is interested in radiation and decides to buy a Geiger counter. He takes his new Geiger counter near the power plant in his town and it starts clicking as he gets closer. As he leaves the area around the power plant and goes home the Geiger counter clicks slower and slower until it almost stops completely.
[EX A]: Which area has more radiation, the power plant or Andre's home?

[EX Q]: Background Paragraph: Huge amounts of chemicals, such as fertilizers and pesticides, are applied to farm fields (see Figure below ). Some of the chemicals are picked up by rainwater. Runoff then carries the chemicals to nearby rivers or lakes. Dissolved fertilizer causes too much growth of water plants and algae. This can lead to dead zones where nothing can live in lakes and at the mouths of rivers. Some of the chemicals can infiltrate into groundwater. The contaminated water comes up in water wells. If people drink the polluted water, they may get sick. 
Story: Lucas is sitting between two lakes, lake Hijem and lake Rarsnap, holding a large bag of fertilizer. His neighbor told him to pour the bag of fertilizer in one of the two lakes, but Lucas can't remember which lake he was told to pour it in. Lucas decides to just guess rather than ask for clarification and pours the whole bag of fertilizer into lake Hijem.
[EX A]: Which lake will have less dead zones?

[EX Q]: Background Paragraph: Hepatitis B is a contagious virus that affects the liver, infection can last from a few weeks to a serious lifelong illness. Two different types of infection exist for this disease, "acute" and "chronic." Acute Hepatitis B is a short term illness that occurs within 6 months of exposure, Chronic Hepatitis B is long term and happens when the virus remains in the body. The younger the child is, the greater their chance of developing a chronic infection and this risk goes down as the child gets older. Approximately 90% of infected infants will develop a chronic infection.[3]. 
Story: A 1st grade classroom photo was held today. They all gathered by age. Larry was the oldest. Jeffrey was the 2nd oldest. Frank was the 3rd oldest. Scott was the 4th oldest. Eric was the 5th oldest. Stephen was the 6th oldest. The last one was Andrew, who was the youngest. They all looked fantastic that day.
[EX A]:
Who has a greater chance of developing a chronic infection: Eric or Andrew?
