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: 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.
[EX A]: Which area more than likely has a higher socioeconomic status within the Hispanic population?

[EX Q]: Background Paragraph: The epidermis also contains melanocytes , which are cells that produce melanin. Melanin is the brownish pigment that gives skin much of its color. Everyone has about the same number of melanocytes, but the melanocytes of people with darker skin produce more melanin. The amount of melanin produced is determined by heredity and exposure to UV light, which increases melanin output. Exposure to UV light also stimulates the skin to produce vitamin D . Because melanin blocks UV light from penetrating the skin, people with darker skin may be at greater risk of vitamin D deficiency.
Story: John is learning more about different cultures and people around the world. He noticed that people have different skin colors. To learn more about the science behind skin colors he categorized the skin colors into two broad groups, case D and case L. Case D is represented by darker skin and case L is represented by lighter skin.
[EX A]: In which case melanocytes would produce less melanin, case D or case L?

[EX Q]: Background Paragraph: There are two basic types of energy in the universe: potential energy and kinetic energy. Potential energy is stored energy that is available to do work, but it has not yet been released. The wood in a fireplace possesses potential energy. It is available for producing heat, but has not yet been ignited, so it is not releasing heat into the surrounding environment. Kinetic energy is the energy of motion. A waterfall is an example of kinetic energy. The moving water can erode the rocks in the stream, wearing them down into smaller particles. This same water motion can turn a turbine to generate electricity. In both cases, the movement of the material (water) causes work to be done.
Story: While out on a hiking trip Ricky stumbles upon a waterfall. While looking at it he notices that the rocks around and behind the waterfall as well as the rocks in the stream it flows into are smooth, When he is no longer near the waterfall the rocks are very jagged and cracked and sharp.
[EX A]:
Will the area near a water fall have sharp or smooth rocks?
