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: A mycorrhiza (Greek for "fungus roots") is a symbiotic association between a fungus and the roots of a plant. In a mycorrhizal association, the fungus may colonize the roots of a host plant by either growing directly into the root cells, or by growing around the root cells. This association provides the fungus with relatively constant and direct access to glucose, which the plant produces by photosynthesis. The mycelia of the fungi increase the surface area of the plant’s root system. The larger surface area improves water and mineral nutrient absorption from the soil. 
Story: Two mycologists studied about mushrooms. Bert studied mycorrhizal fungi, while Vince studied saprophytic mushrooms.
[EX A]: Which person studied a bit less about mineral nutrient absorption from the soil?

[EX Q]: Background Paragraph: Other pathogens spread when they get on objects or surfaces. A fungus may spread in this way. For example, you can pick up the fungus that causes athlete’s foot by wearing shoes that an infected person has worn. You can also pick up this fungus from the floor of a public shower or other damp areas. After acne, athlete’s foot is the most common skin disease in the United States. Therefore, the chance of coming in contact with the fungus in one of these ways is fairly high. 
Story: Two people, Jim and John, are discussing their shower ritual for the morning. John takes his shower in his own apartment that he lives in by himself. Jim always takes his showers at the public gym after he finishes his workout.
[EX A]: Which person is less likely to contract athlete's foot?

[EX Q]: Background Paragraph: Artworks are sold at affordable prices [6] ranging from £5 to £1500. For many of the works, the price goes up as the edition sells out. The edition runs range from 30 to 10,000 editions. Each work comes with a digital certificate that is “signed, numbered and authenticated by the artist” [7][8] Once an edition is sold out, collectors can resell their works in the online marketplace. 
Story: A new art store had limited edition artworks for sale last week. They all had 300 pieces at the beginning of the week. By the end of the week, they started to sell out. There were only 5 Impression Sunrise, 20 Las Meninas, 50 The Creation Of Adam, 100 Luncheon Of The Boating Party, 100 The Grand Odalisque, 200 The Swing, and 250 The Liberty Leading The People left.
[EX A]:
What edition will most likely have it's price increased: Las Meninas or Impression Sunrise?
