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.

Example Input: 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 red drone the highest into the air. Team A got it 2,501 ft. Team B got it 3,501 ft. Team C go it 4,501 ft. Team D got it 5,501 ft. Team E got it 10,501 ft. Team F got it 13,501 ft. Team G got it 14,501 ft. Team G won the contest and got a gold trophy as the prize. 
Question: What team got their drone into high altitude: Team D or Team E?
Example Output: Team E.

Example Input: Background Paragraph: If all the other factors influencing humidity remain constant, at ground level the relative humidity rises as the temperature falls. This is because less vapor is needed to saturate the air, so vapor condenses as the temperature falls. In normal conditions, the dew point temperature will not be greater than the air temperature because relative humidity cannot exceed 100%.[4]. 
Story: Sam lived in Chicago for many years and experienced those high humidity days during the summer, the Indian summers in October and harsh and humid winters, so he decided to move to San Diego, in a warmer and much dryer climate. 
Question: Which city has less fog during summer?
Example Output: San Diego.

Example Input: Background Paragraph: They feed on living hosts. As parasites , fungi live in or on other organisms and get their nutrients from their host. Parasitic fungi use enzymes to break down living tissue, which may causes illness in the host. Disease-causing fungi are parasitic. Recall that parasitism is a type of symbiotic relationship between organisms of different species in which one, the parasite, benefits from a close association with the other, the host, which is harmed. 
Story: Two botanists had different interests, Mike studied only trees and flowers, while Chris was fascinated with studying fungi. 
Question: Which botanist learned more about parasitism?
Example Output:
Chris.
