instruction:
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.

Background Paragraph: Circadian rhythms are regular changes in biology or behavior that occur in a 24-hour cycle. In humans, for example, blood pressure and body temperature change in a regular way throughout each 24-hour day. Animals may eat and drink at certain times of day as well. Humans have daily cycles of behavior, too. Most people start to get sleepy after dark and have a hard time sleeping when it is light outside. In many species, including humans, circadian rhythms are controlled by a tiny structure called the biological clock . This structure is located in a gland at the base of the brain. The biological clock sends signals to the body. The signals cause regular changes in behavior and body processes. The amount of light entering the eyes helps control the biological clock. The clock causes changes that repeat every 24 hours. 
Story: Jason is an average guy who goes to work each day, lives in an apartment, exercises sometimes, goes out and drinks some weekends and just generally enjoys life. Brad, however, has chosen to live in a dark cave that has no windows. He lives in a cave that has almost no light except for some candles he lights from time to time. If he needs food or supplies, he pays someone to go get them, and they slide them through a hole that can open in the steel door at the entrance of the cave. 
Question: Will Jason's biological clock be more or less out of control than Brad's?
answer:
less.


question:
Background Paragraph: Regions on the Earth's surface (or in its atmosphere) that are high above mean sea level are referred to as high altitude. High altitude is sometimes defined to begin at 2,400 meters (8,000 ft) above sea level.[5][6][7]

At high altitude, atmospheric pressure is lower than that at sea level. This is due to two competing physical effects: gravity, which causes the air to be as close as possible to the ground; and the heat content of the air, which causes the molecules to bounce off each other and expand.[8]. 
Story: There was a competition for who can get the model plane highest into the air. Team 1 got it 1,000 ft. Team 2 got it 2,000 ft. Team 3 go it 4,000 ft. Team 4 got it 9,000 ft. Team 5 got it 10,000 ft. Team 6 got it 12,000 ft. Team 7 got it 13000 ft. Team 7 won the contest and got a gold trophy as the prize. 
Question: What team got their kite into high altitude: Team 3 or Team 7?
answer:
Team 7.


question:
Background Paragraph: East Antarctica is colder than its western counterpart because of its higher elevation. Weather fronts rarely penetrate far into the continent, leaving the centre cold and dry. Despite the lack of precipitation over the central portion of the continent, ice there lasts for extended periods. Heavy snowfalls are common on the coastal portion of the continent, where snowfalls of up to 1.22 metres (48 in) in 48 hours have been recorded. 
Story: Two teams of scientists were in Antarctica to study the weather. Camp Alpha was located in East Antarctica, while camp Omega was situated in West Antarctica. 
Question: Which camp didn't observe that ice there lasts for extended periods?
answer:

Omega.
