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: Alcoholic beverages do not make the entire body warmer.[361] The reason that alcoholic drinks create the sensation of warmth is that they cause blood vessels to dilate and stimulate nerve endings near the surface of the skin with an influx of warm blood. This can actually result in making the core body temperature lower, as it allows for easier heat exchange with a cold external environment.
Story: A research institute is investigating the effect of alcohol in human body. They gave two groups of subjects, group blue and group red, two different drinks, labeled as blue drink and red drink. The blue drink contained alcohol, and the red drink did not contain any alcohol. Blue drinks were given to the blue group and the red drinks were given to the red group.
[EX A]: Which group would have dilated blood vessels?

[EX Q]: Background Paragraph: One of the main causes of extinction is introduction of exotic species into an environment. These exotic and new species can also be called invasive species or non-native species . These non-native species, being new to an area, may not have natural predators in the new habitat, which allows their populations to easily adapt and grow. Invasive species out-compete the native species for resources. Sometimes invasive species are so successful at living in a certain habitat that the native species go extinct ( Figure below ).
Story: India decided to introduce several exotic species into their environment, while Singapore was very protective of its native species. India encountered big problems with extinction during the following years.
[EX A]: Which country didn't observe that invasive species out-compete the native species for resources?

[EX Q]: Background Paragraph: When using measuring devices, we often use a technique called calibration to increase the accuracy of our measurements. Calibration is a method of setting or correcting a measuring device by matching it to known measurement standards. To better understand calibration, we will look at the example of calibrating a thermometer. All thermometers are slightly different in their temperature readings. One way to calibrate a thermometer is by using the freezing point and boiling point of water ( Figure below ). If we know that water freezes at 0C and boils at 100C, we can calibrate our thermometer by measuring the temperature of ice water and of boiling water. We place the thermometer in ice water and wait for the thermometer liquid to reach a stable height, then place a mark at this height which represents 0C. Then we place the thermometer in boiling water, and after waiting for the thermometer liquid to reach a stable height, we place a mark at this height which represents 100C. We can then place 100 equally spaced divisions between our 0 and 100C marks to each represent 1C. Our thermometer has now been calibrated using the known values for the freezing point and boiling point of water, and can be used to measure temperatures of objects between 0 and 100C.
Story: While working on a touch screen laptop, Chris notices that his button presses seem to not be connecting where he presses on the screen. He opens up a calibration application and resets everything. The program then asks him to touch the screen where a button is in different locations on the screen.
[EX A]:
Will properly running the calibration application likely increase or decrease the accuracy of Chris' touch screen?
