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.

Input: Consider 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: Antwan had a busy day storing XML. In the morning, he filled up a hard drive with XML. In the afternoon, he filled up a few hard drives with XML. At night, he filled up many hard drives with XML. 
Question: What time did the access times go up the most: afternoon or night?

Output: night.


Input: Consider Input: Background Paragraph: We discussed earlier some basic principles about the behavior of gases called the kinetic-molecular theory. Among other things, this theory suggests that gas molecules are in constant motion, and the average speed of the individual gas particles is dependent upon temperature – the higher the temperature, the faster the molecules move. It is not just gas particles that are in constant motion. The molecules and ions that make up liquids and solutions are also continually moving in nearly random directions. As a result, molecules and ions in a solution will collide with one another fairly frequently. As with gases, a temperature increase will produce an increase in the average particle speed. 
Story: Scientists are observing two of the same gases at different temperatures. They are observing the speed of the particles in the gases to see how fast they are moving. Gas A has particles moving very quickly, but Gas B has particles that are hardly moving at all. 
Question: Which gas is at a lower temperature?

Output: Gas B.


Input: Consider Input: Background Paragraph: Clouds on Earth are made of water vapor. Venus's clouds are a lot less pleasant. They are made of carbon dioxide, sulfur dioxide and large amounts of corrosive sulfuric acid! The atmosphere of Venus is so thick that the pressure on the surface of Venus is very high. In fact, it is 90 times greater than the pressure at Earth’s surface! The thick atmosphere causes a strong greenhouse effect. As a result, Venus is the hottest planet. Even though it is farther from the Sun, Venus is much hotter even than Mercury. Temperatures at the surface reach 465°C (860°F). That’s hot enough to melt lead!. 
Story: In year 2200, David is an astronaut and an avid galaxy hopper from a planet hundred light years away. He ended up in the solar system in search of water. He identified three planets, planet A, planet B and planet C. Little did he know that less than a hundred years ago people used to call planet A as Earth, planet B as Venus, and planet C as Mercury. 
Question: Would planet B have higher or lower pressure on the surface than planet A?


Output: higher.
