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: 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 2nd grade classroom photo was held today. They all gathered by age. Larry was the youngest. Jeffrey was the 2nd youngest. Frank was the 3rd youngest. Scott was the 4th youngest. Eric was the 5th youngest. Stephen was the 6th youngest. The last one was Andrew, who was the oldest. They all looked great that day.
[EX A]: Who has a greater chance of developing a chronic infection: Andrew or Larry?

[EX Q]: Background Paragraph: A car's gas pedal, like the one in Figure below , is sometimes called the accelerator. That's because it controls the acceleration of the car. Pressing down on the gas pedal gives the car more gas and causes the car to speed up. Letting up on the gas pedal gives the car less gas and causes the car to slow down. Whenever an object speeds up, slows down, or changes direction, it accelerates. Acceleration is a measure of the change in velocity of a moving object. Acceleration occurs whenever an object is acted upon by an unbalanced force.
Story: Jordan and Alejandro are drivers currently in an intense car race. Some dust blows into Jordan's car, causing him to sneeze and take his foot off of the gas pedal. At the same time, Alejandro gets a burst of adrenaline and presses down
very hard on the gas pedal in his car.
[EX A]: Who will cause their car to decrease in speed?

[EX Q]: Background Paragraph: Pollutants also affect the atmosphere through their contribution to global warming. Global warming is an increase in the Earth's temperature. It is thought to be caused mostly by the increase of greenhouse gases like carbon dioxide. Greenhouse gases can be released by factories that burn fossil fuels. Over the past 20 years, burning fossil fuels has produced about three-quarters of the carbon dioxide from human activity. The rest of the carbon dioxide in the atmosphere is there because of deforestation, or cutting down trees ( Figure below ). Trees absorb carbon dioxide during cellular respiration, so when trees are cut down, they cannot remove carbon dioxide from the air.
Story: Quebec recently removed a large area consisting primarily of forests in order to make room for a new housing development. On the other hand, Montreal recently finished planting a large amount of new trees as part of an environmental initiative project.
[EX A]:
Which area will remove higher levels of carbon dioxide from the air, Montreal or Quebec?
