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: Saturated hydrocarbons are given the general name of alkanes . The name of specific alkanes always ends in – ane . The first part of the name indicates how many carbon atoms each molecule of the alkane has. The smallest alkane is methane. It has just one carbon atom. The next largest is ethane with two carbon atoms. The chemical formulas and properties of methane, ethane, and other small alkanes are listed in the Table below . The boiling and melting points of alkanes are determined mainly by the number of carbon atoms they have. Alkanes with more carbon atoms generally boil and melt at higher temperatures. 
Story: Scientists are studying two alkanes in a laboratory, Mophane and Tripane. Scientists are analyzing the various characteristics of these alkanes to be used in future scientific studies. They discover that Mophane has more carbon atoms than Tripane. This information will definitely be useful in the future!.

Answer: Which alkane has a higher boiling point?


Question: 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. As a result, they are more likely to bump into one another and to collide with greater force. For example, food spoils because of chemical reactions, and these reactions occur faster at higher temperatures (see the bread on the left in the Figure below ). This is why we store foods in the refrigerator or freezer (like the bread on the right in the Figure below ). The lower temperature slows the rate of spoilage. 
Story: A scientist is observing two chemicals react. The reaction is very slow and he wants to find a way to speed up the reaction. One day the labs air conditioner breaks and he notices the reaction is happening significantly faster than usual.

Answer: Given two batches of chemicals, Batch A at 20 degrees celcius and batch B at 45 degrees C, which will react faster?


Question: Background Paragraph: East Antarctica is colder than its western counterpart because of its higher elevation. Weather fronts rarely penetrate far into the continent, leaving the centre cold and dry. Despite the lack of precipitation over the central portion of the continent, ice there lasts for extended periods. Heavy snowfalls are common on the coastal portion of the continent, where snowfalls of up to 1.22 metres (48 in) in 48 hours have been recorded. 
Story: UK and France had scientific bases in Antarctica. UK had a base and studied the climate in East Antarctica, while France observed the climate in West Antarctica.

Answer:
Which country didn't observe ice lasting for extended periods?
