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."

Background Paragraph: Atmospheric convection is the result of a parcel-environment instability, or temperature difference layer in the atmosphere. Different lapse rates within dry and moist air masses lead to instability. Mixing of air during the day which expands the height of the planetary boundary layer leads to increased winds, cumulus cloud development, and decreased surface dew points. Moist convection leads to thunderstorm development, which is often responsible for severe weather throughout the world. Special threats from thunderstorms include hail, downbursts, and tornadoes.
Story: Boone county experienced severe weather last week as a result of atmospheric convection. White county to the east experienced some rain but was sheltered from this phenomenon because of the mountain range.

Ex Output:
Which county experienced less different lapse rates within dry and moist air masses?

Background Paragraph: Making these healthy lifestyle choices can also help prevent some types of cancer. In addition, you can lower the risk of cancer by avoiding carcinogens , which are substances that cause cancer. For example, you can reduce your risk of lung cancer by not smoking. You can reduce your risk of skin cancer by using sunscreen. How to choose a sunscreen that offers the most protection is explained below ( Figure below ). Some people think that tanning beds are a safe way to get a tan. This is a myth. Tanning beds expose the skin to UV radiation. Any exposure to UV radiation increases the risk of skin cancer. It doesn't matter whether the radiation comes from tanning lamps or the sun.
Story: Steve and Bill are really good friends with each other. The other day they were talking about some habits they have. Steve likes to work out and stay in shape, eats healthy and does not smoke. Bill said he wants to be more like Steve. Bill currently smokes, and loves to go out tanning in the sun without sunscreen.

Ex Output:
Which of the two men better avoids carcinogens?

Background Paragraph: When the temperature of reactants is higher, the rate of the reaction is faster. At higher temperatures, particles of reactants have more energy, so they move faster. They are more likely to bump into one another and to collide with greater force. For example, when you fry an egg, turning up the heat causes the egg to cook faster. The same principle explains why storing food in a cold refrigerator reduces the rate at which food spoils (see Figure below ). Both food frying and food spoiling are chemical reactions that happen faster at higher temperatures.
Story: A chef is currently cooking two sausages on different skillets on different burners. These burners are affectionately referred to as Burno and Bako by the staff of the restaurant. These burners do not have temperature readouts though, and instead the chefs rely on chemical analysis to determine things such as heat levels. The chef notices that the sausage cooking on Burno currently has particles moving very quickly, but the one on Bako has particles that are barely moving at all.

Ex Output:
The sausage on which burner has reactants with less energy?
