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: The Mercator projection is best within 15 degrees north or south of the equator. Landmasses or countries outside that zone get stretched out of shape. The further the feature is from the equator, the more out of shape it is stretched. For example, if you look at Greenland on a globe, you see it is a relatively small country near the North Pole. Yet, on a Mercator projection, Greenland looks almost as big the United States. Because Greenland is closer to the pole, the continent's shape and size are greatly increased. The United States is closer to its true dimensions. 
Story: Bob is looking at a map with Mercator projection to help him with his geography class. He noticed that Ecuador is within fifteen degrees north or south of the equator, but Norway is farther north of the equator. Bob starts to see how a country's location on a map affects how they look.

Ex Output:
If they were equal in size on a globe, which country would look bigger on a map, Equador or Norway?

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: Two groups of students made some experiments for school. Group A used brewer's yeast on flower and tried to make bread. and Group B brewed beer with brewer's yeast. the experiments happened vice-versa as well.

Ex Output:
Which group made better beer?

Background Paragraph: As shown here, pressure decreases to less than 25% of ground-level atmospheric pressure when we get to an altitude of about six miles. Since this is a common cruising altitude for commercial airplanes, pressurized cabins are needed for the comfort and survival of the passengers. This is because the density of the air decreases along with the decreasing air pressure, so there is less oxygen in a breath of air. You've probably noticed this effect in high-mountain areas, as it often feels harder to breath. 
Story: Marco is sitting at the bottom of a mountain and painting a picture of it. Lauren, Marco's friend, is sitting about halfway up the mountain and painting a picture of the horizon. The two will compare paintings after they complete their drawings and then will switch places and repeat the task. These two friends do this a couple times a year, and they always enjoy seeing how the other person paints the same object.

Ex Output:

Is the air by Lauren more or less dense than the air by Marco?
