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 are also given a question about the story that requires an understanding of the relationship described in the background paragraph and the story. You need to come up with an answer to the given question; the answer will be a span from either the question or the story. In order to correctly answer the given question, you need to understand the relationship mentioned in the background paragraph and should be able to use it to understand that in the story. Your answer can not consist of any word that is not mentioned in any of these: the background paragraph, the story, or the question. You can directly copy and paste a span from the story or the question while answering the given question.

Example Input: Background Paragraph: Storing large volumes of data When storing XML to either file or database, the volume of data a system produces can often exceed reasonable limits, with a number of detriments: the access times go up as more data is read, CPU load goes up as XML data takes more power to process, and storage costs go up. By storing XML data in Fast Infoset format, data volume may be reduced by as much as 80 percent.
Story: Dan had a busy day storing XML. At 2 PM, he stored 10000 Gigabytes to the database. At 3 PM, he stored 20000 Gigabytes to the database. At 4 PM, he stored 30000 Gigabytes to the database. At 5 PM, he got dinner. At 6 PM, he stored 40000 Gigabytes to the database. At 7 PM, he stored 50000 Gigabytes to the database. At 8 PM, he went to sleep to finish storing XML in the morning.
Question: What time did CPU load go up: 3 PM or 5 PM?
Example Output: 3 PM.

Example Input: Background Paragraph: Shown in the Figure below is a cylinder of gas on the left that is at room temperature (300 K). On the right, the cylinder has been heated until the Kelvin temperature has doubled to 600 K. The kinetic energy of the gas molecules increases, so collisions with the walls of the container are now more forceful than they were before. As a result, the pressure of the gas doubles. Decreasing the temperature would have the opposite effect, and the pressure of an enclosed gas would decrease.
Story: In a laboratory, Marcus is working with two identical containers of the same amount of gas inside them. For his next experiment, he needs these containers to be different temperatures. He takes container X and puts it in the refrigerator, and he leaves container Y out on the table. One hour later, he comes back and takes container X out of the refrigerator so he can now begin his experiment.
Question: Which container has more kinetic energy?
Example Output: container Y.

Example Input: Background Paragraph: Astronomy is very sensitive to light pollution. The night sky viewed from a city bears no resemblance to what can be seen from dark skies.[78] Skyglow (the scattering of light in the atmosphere at night) reduces the contrast between stars and galaxies and the sky itself, making it much harder to see fainter objects. This is one factor that has caused newer telescopes to be built in increasingly remote areas.
Story: Diana is studying astronomy and in her spare time likes to stargaze. She has never been outside of her large city however. One weekend she got to go on a camping trip with her parents. When they arrived at the campsite, which is very far from the lights of the city she noticed the number of stars she could see in the sky greatly increased.
Question: Will being in a city increase or decrease the number of visible stars?
Example Output:
decrease.
