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: The Hawaiian Islands ( Figure above ) are in the central Pacific Ocean. The islands are volcanoes that increase in age from southeast to northwest. The youngest island is the Big Island of Hawaii at the southeast end of the chain. The volcanoes get older through Maui, Kahoolawe, Lanai, Molokai, Oahu, Kauai, and Niihau Islands through the northwest. The Kilauea volcano on Hawaii has been erupting almost continuously since 1983. There are also eruptions at an underwater volcano called Loih. 
Story: Tom and Brad were good friends but lived far away from each other. Tom lived in Hawaii so he visited all the islands and the volcanoes frequently. Brad lived on the East Coast, and he never visited The Hawaiian Islands. 
Question: Which friend lived farther from the Big Island of Hawaii?
Example Output: Brad.

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 25 lb drone the highest into the air. Team 60 got it 3,338 ft. Team 61 got it 4,449 ft. Team 62 go it 5,550 ft. Team 63 got it 6,661 ft. Team 64 got it 11,116 ft. Team 65 got it 12,227 ft. Team 66 got it 13,337 ft. 
Question: What team got their drone into high altitude: Team 60 or Team 65?
Example Output: Team 65.

Example Input: Background Paragraph: HIV , or human immunodeficiency virus, causes AIDS. AIDS stands for "acquired immune deficiency syndrome." It is a condition that causes death and does not have a known cure. AIDS usually develops 10 to 15 years after a person is first infected with HIV. The development of AIDS can be delayed with proper medicines. The delay can be well over 20 years with the right medicines. Today, individuals who acquire HIV after 50 years of age can expect to reach an average human life span. 
Story: Two college buddies have known each other for 20 years. Tim was HIV positive while John was not and he didn't have a problem with it. 
Question: Which friend has a smaller chance of developing AIDS?
Example Output:
John.
