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: Enzymes increase the rate of chemical reactions by reducing the amount of activation energy needed for reactants to start reacting. One way this can happen is modeled in the Figure below . Enzymes aren't changed or used up in the reactions they catalyze, so they can be used to speed up the same reaction over and over again. Each enzyme is highly specific for the particular reaction is catalyzes, so enzymes are very effective. A reaction that would take many years to occur without its enzyme might occur in a split second with the enzyme. Enzymes are also very efficient, so waste products rarely form.
Story: A scientist is testing chemical reactions. At first he tries mixing two chemicals together at a temperature of 85 degrees Celsius and labels it Trial A. He records the time for the reaction to complete at 2 minutes. Knowing that this isn't the temperature users at home will be combining the chemicals at he tries the reaction again at a more modest 65 degrees Celsius and labels this trial B. Noting this temperature the reaction takes almost 4 times as long which is completely unacceptable, He then gets an idea to add and enzyme designed specifically for these two chemicals and then tries the reaction at the modest 65 degrees Celsius again calling this one trial C.
Question: Given the specifically designed enzyme is added to Trial A, will the required activation energy increase or decrease?

Ex Output:
decrease.

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 kite highest into the air. Team A got it 2,000 ft. Team B got it 3,000 ft. Team C go it 6,000 ft. Team D got it 9,000 ft. Team E got it 10,000 ft. Team F got it 11,000 ft. Team G got it 12,000 ft. Team G won the contest and got a gold trophy as the prize.
Question: What team got their kite into high altitude: Team C or Team F?

Ex Output:
Team F.

Background Paragraph: Communication is any way that animals share information. Many animals live in social groups. For these animals, being able to communicate is essential. Communicating increases the ability of group members to cooperate and avoid conflict. Communication may help animals work together to find food and defend themselves from predators. It also helps them find mates and care for their offspring. In addition, communication helps adult animals teach the next generation learned behaviors. Therefore, communication generally improves the chances of animals surviving and reproducing.
Story: There are 2 groups of prairie dogs that have been released into the wild. Group A was domesticated and therefor never learned to communicate danger to each other. Group B was rescued from a bad storm but lived in the wild for years before they were captured then released. One day the two groups encountered a lion that was trying to eat them. One of the members of group B made a peculiar high pitched sound, alerting the rest of it's members that there was something dangerous nearby and they all went inside their burrow and hid. The member of group A saw the lion and simply ran as fast as it could without altering any of the other members. Unfortunately one of group A's members was caught and eaten.
Question: Which group has a better chance of survival in the wild, Group A or group B?

Ex Output:
B.
