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."

Question: Background Paragraph: Blue ice occurs when snow falls on a glacier, is compressed, and becomes part of the glacier. Air bubbles are squeezed out and ice crystals enlarge, making the ice appear blue.

Small amounts of regular ice appear to be white because of air bubbles inside them and also because small quantities of water appear to be colourless. In glaciers, the pressure causes the air bubbles to be squeezed out, increasing the density of the created ice. Large quantities of water appear to be blue, as it absorbs other colours more efficiently than blue. A large piece of compressed ice, or a glacier, similarly appears blue.
Story: Bill is going to see some sites this week. On Wednesday he is going to see Fox Glacier, and on Thursday he is going to see Cobra Lake, which has frozen over for the winter. He has been excited to see all the sites.

Answer: Of the two places Bill is going, which ice will have the least density?

Question: Background Paragraph: An allergy is a disease in which the immune system makes an inflammatory response to a harmless antigen . Any antigen that causes an allergy is called an allergen. Allergens may be inhaled or ingested, or they may come into contact with the skin. Two common causes of allergies are shown in Figure below . Inhaling ragweed pollen may cause coughing and sneezing. Skin contact with oils in poison ivy may cause an itchy rash. Other common causes of allergies include dust mites, mold, animal dander, insect stings, latex, and certain food and medications. Symptoms of a common allergy such as pollen can include sneezing, a runny nose, nasal congestion and itchy, watery eyes.
Story: Two roommates, Karen and Kelly, have decided to adopt a pet for their apartment. They are debating between getting a dog or a cat when they decide to flip a coin since they can't agree. The coin comes up tails so they are getting a cat. Unbeknownst to Karen, she is allergic to cats. Kelly has no allergies to animals, but Karen has never lived with cats before so she isn't aware that she is allergic to them.

Answer: Who will have a stuffy nose less often?

Question: Background Paragraph: Lifting an object in a gravitational field requires work and increases the object's potential energy. A similar situation occurs when you move two charged objects relative to each other. We already know that each object has an electric field surrounding it, which effects the other charge. If the two charged objects have the same charge, they repel each other. Moving these two objects closer to each other requires working against the repulsive force, which increases the potential energy of the system. Conversely, moving two like charges apart will decrease the potential energy. If the objects attract each other, the opposite situtations occur if you pull them apart, you do work against the force, which increases the potential energy of the system, but bringing attractive charges closer together decreases the potential energy.
Story: A small boy is playing with some magnets. He takes the north ends of 2 magnets and tries to push them together, he gets them close and lets one of watching it bounce backwards. He then takes two opposite poles and slowly pushes them together.

Answer:
Will pushing 2 of the same poles of a magnet together increase or decrease the potential energy?
