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 Q]: Background Paragraph: When the temperature of reactants is higher, the rate of the reaction is faster. At higher temperatures, particles of reactants have more energy, so they move faster. They are more likely to bump into one another and to collide with greater force. For example, when you fry an egg, turning up the heat causes the egg to cook faster. The same principle explains why storing food in a cold refrigerator reduces the rate at which food spoils (see Figure below ). Both food frying and food spoiling are chemical reactions that happen faster at higher temperatures. 
Story: Ned learned about reactions at a higher temperature for his physics class, while Paul had to learn about reactions at lower temperatures. 
Question: Which person didn't study about the heat causing the egg to cook faster?
[EX A]: Paul.

[EX Q]: Background Paragraph: Like water in the ocean, air in the atmosphere exerts pressure that increases with depth. Most gas molecules in the atmosphere are pulled close to Earth’s surface by gravity. As a result, air pressure decreases quickly at lower altitudes and then more slowly at higher altitudes. This is illustrated in Figure below . Air pressure is greatest at sea level, where the depth of the atmosphere is greatest. At higher altitudes, the pressure is less because the depth of the atmosphere is less. For example, on top of Mount Everest, the tallest mountain on Earth, air pressure is only about one-third of the pressure at sea level. At such high altitudes, low air pressure makes it hard to breathe and is dangerous to human health. 
Story: Robert and his brother Timothy are both marathon runners. As marathon running is an endurance event, a key component is being able to replenish your oxygen supply by taking frequent breaths. This week, Robert is running a marathon in Colorado, which has low air pressures. Timothy is  also running a marathon, but he is running in Florida, which has high air pressures. 
Question: Who will have less difficulty in keeping a steady supply of oxygen during their marathon?
[EX A]: Timothy.

[EX Q]: 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 their gray drone the highest into the air. Team 20 got it 3,334 ft. Team 21 got it 4,445 ft. Team 22 go it 5,556 ft. Team 23 got it 6,667 ft. Team 24 got it 11,112 ft. Team 25 got it 12,223 ft. Team 26 got it 13,333 ft. 
Question: What team got their drone into high altitude: Team 23 or Team 24?
[EX A]:
Team 24.
