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.

Input: Consider Input: Background Paragraph: Air pollution is harmful to human beings and other living things. About 22 million people die from air pollution each year. Breathing polluted air increases the risk of developing lung diseases such as asthma and lung cancer. Breathing bad air also increases the chances of dying from other diseases. Children are most likely to be affected by air pollution. That’s because their lungs are still developing and growing. Children also take in more air for their size than adults do. Some air pollutants damage the environment as well as the health of living things. The type of damage depends on the pollutant. Air pollution can also harm the environment. 
Story: Michael and Thomas are brothers whose careers have taken them to different cities. Michael lives in Beijing, where the levels of air pollution are fairly high due to the extensive manufacturing industry. Thomas, on the other hand, lives in Seattle, which has low levels of air pollution thanks to government initiatives and culture attitudes in the region. 
Question: Who has a higher risk of developing asthma?

Output: Michael.


Input: Consider Input: Background Paragraph: Almost all earthquakes occur at plate boundaries. All types of plate boundaries have earthquakes. Convection within the Earth causes the plates to move. As the plates move, stresses build. When the stresses build too much, the rocks break. The break releases the energy that was stored in the rocks. The sudden release of energy is an earthquake. During an earthquake the rocks usually move several centimeters. Rarely, they may move as much as a few meters. Elastic rebound theory describes how earthquakes occur ( Figure below ). 
Story: Tim the seismologist studied data from two cities: Tokyo and Kansas City. Tokyo experienced many more earthquakes than Kansas City. 
Question: Which city experiences more energy release because of rocks breaking?

Output: Tokyo.


Input: Consider 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: Ken is an avid mountain climber. This year he reached the summits of two mountains, mountain A and mountain B. Mountain A is only 5000 ft tall while mountain B is 
15000 ft tall. He has also learned a fun fact that water boils faster and at lower temperature at low atmospheric pressure. 
Question: If Ken wants to boil water slower, which mountain summit would he choose, mountain summit A or mountain summit B?


Output: mountain summit A.
