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.

Ex Input:
Background Paragraph: Centripetal force is, simply, the force that causes centripetal acceleration. Objects that move in uniform circular motion all have an acceleration toward the center of the circle and therefore, they must also suffer a force toward the center of the circle. That force is the centripetal force. For orbiting satellites, such as the moon orbiting the earth or the earth orbiting the sun, the centripetal force is produced by gravity. When an Olympic hammer thrower whirls a massive ball on a chain, the centripetal force is created by the athlete and transmitted by the chain. 
Story: Adam wants to show his little brother a trick.  He gets a bucket of water and says to him "I bet i can turn this bucket upside down and no water will fall out". His brother doesn't believe him of course. So Adam takes the bucket by the handle and quickly starts spinning it in a circle. 
Question: Given Adam stops swinging the bucket, will its centripetal acceleration increase or decrease?

Ex Output:
decrease.

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: Odis had a busy day storing XML. At 8 AM, he stored 202 Gigabytes to the database. At 9 AM, he stored 302 Gigabytes to the database. At 10 AM, he stored 402 Gigabytes to the database. At 11 AM, he got breakfast. At 12 PM, he stored 502 Gigabytes to the database. At 1 PM, he stored 602 Gigabytes to the database. At 2 PM, she went to sleep to finish storing XML later on that night. 
Question: What time did access times go up: 9 AM or 2 PM?

Ex Output:
9 AM.


Ex Input:
Background Paragraph: The body's second line of defense against pathogens includes the inflammatory response. If bacteria enter the skin through a scrape, the area may become red, warm, and painful. These are signs of inflammation. Inflammation is one way the body reacts to infections or injuries. Inflammation is caused by chemicals that are released when skin or other tissues are damaged. The chemicals cause nearby blood vessels to dilate, or expand. This increases blood flow to the damaged area, which makes the area red and slightly warm. The chemicals also attract white blood cells called neutrophils to the wound and cause them to leak out of blood vessels into the damaged tissue. 
Story: Two medical students learned about the human body's defense against pathogens. Niles learned about the body's first line of defense, while Bill  learned more about the inflammatory response. 
Question: Which student learned less about skin becoming red?

Ex Output:

Niles.
