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."

Example Input: Background Paragraph: Baker's yeast is the common name for the strains of yeast commonly used in baking bread and bakery products, serving as a leavening agent which causes the bread to rise (expand and become lighter and softer) by converting the fermentable sugars present in the dough into carbon dioxide and ethanol. Baker's yeast is of the species Saccharomyces cerevisiae,[1] and is the same species (but a different strain) as the kind commonly used in alcoholic fermentation, which is called brewer's yeast.[2] Baker's yeast is also a single-cell microorganism found on and around the human body. 
Story: the students used yeasts in two different experiments: they baked bread using baker's yeast, and made beer, using brewer's yeast. They learned a lot about sugars and chemistry.
Example Output: Which yeast is better for alcoholic fermentation?

Example Input: Background Paragraph: Existing data on the role of immigration on residential segregation trends in the US suggest that foreign-born Hispanics, Asians and blacks often have higher rates of segregation than do native-born individuals from these groups. Segregation of immigrants is associated with their low-income status, language barriers, and support networks in these enclaves. Research on assimilation shows that while new immigrants settle in homogenous ethnic communities, segregation of immigrants declines as they gain socioeconomic status and move away from these communities, integrating with the native-born. 
Story: A recent study has been published about two U.S cities containing large Hispanic population and their origins. Los Angeles which has a larger native born population, and San Diego, which is formed mostly of immigrants that have been foreign-born, have been listed as the top two.
Example Output: Which area more than likely has a higher socioeconomic status within the Hispanic population?

Example Input: Background Paragraph: In grassland, much of the organic matter added to the soil is from the deep, fibrous, grass root systems. By contrast, tree leaves falling on the forest floor are the principal source of soil organic matter in the forest. Another difference is the frequent occurrence in the grasslands of fires that destroy large amounts of aboveground material but stimulate even greater contributions from roots. Also, the much greater acidity under any forests inhibits the action of certain soil organisms that otherwise would mix much of the surface litter into the mineral soil. As a result, the soils under grasslands generally develop a thicker A horizon with a deeper distribution of organic matter than in comparable soils under forests, which characteristically store most of their organic matter in the forest floor (O horizon) and thin A horizon. 
Story: Kim and Jane inherited some land. Kim inherited some grassland, while Jane inherited a forest. They both took good care of their properties.
Example Output:
Which person inherited a parcel where fewer fires occurred?
