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: We all enjoy a cool dip in a swimming pool on a hot day, but we may not realize the work needed to keep that water safe and healthy. The ideal pH for a swimming pool is around 7.2. The pH will change as a result of many factors. Adjustment can be accomplished with different chemicals depending on the tested pH. High pH can be lowered with liquid HCl (unsafe material) or sodium bisulfate. The bisulfate anion is a weak acid and can dissociate partially in solution. To increase pH, use sodium carbonate. The carbonate anion forms an equilibrium with protons that results in some formation of carbon dioxide. 
Story: Tom and John are both pool owners. Tom prefers to use sodium bisulfate in his pool because he enjoys the smell. John, however, prefers using sodium carbonate in his pool because he believes it helps keep pests away.
[EX A]: Whose pool will have a higher pH?

[EX Q]: Background Paragraph: Pulmonary fibrosis (literally "scarring of the lungs") is a respiratory disease in which scars are formed in the lung tissues, leading to serious breathing problems. Scar formation, the accumulation of excess fibrous connective tissue (the process called fibrosis), leads to thickening of the walls, and causes reduced oxygen supply in the blood. As a consequence patients suffer from perpetual shortness of breath.[1]. 
Story: Air pollution is a big problem in large industrial cities. New York has its share or air pollution. John is a doctor who works for a New York hospital. Today, he is seeing two patients, patient A and patient B. His diagnosis revealed that patient A has pulmonary fibrosis, but patient B does not have pulmonary fibrosis.
[EX A]: In which patient John didn't find thickening of lung walls, patient A or patient B?

[EX Q]: Background Paragraph: When peer feedback is established it allows students to interact with their peers and creates high social skills while learning material more effectively. Interaction with other students allows students to have better social approaches when interacting. Learning by peer feedback gives students more of an opportunity to work as a unit instead of individuals working alone. Working in groups gives students more useful life skill that well help prepare them for the future. Peer feedback gives more control to the student, the student can decide if they want to use the criticism their peers are giving them or not. When given options more students are more likely to give and absorb more feedback. Peer feedback has confirmed an increase in affect; students that have increasing responsibilities have more drive towards their work and a spike in confidence.[6] Furthermore, Kristanto (2018) found that peer feedback is an essential element of peer assessment. In peer assessment, feedback from peers can provide suggestions or correction for students' future works as companion of the received grade.[7]. 
Story: Two college groups did a one year experiment on each other. One group called Group Alpha spend more time and worked together. Group Beta let it's members study on their own and be less dependent on the group. Group Alpha had better results.
[EX A]:
Which group experienced decreased confidence?
