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: Alcoholic beverages do not make the entire body warmer.[361] The reason that alcoholic drinks create the sensation of warmth is that they cause blood vessels to dilate and stimulate nerve endings near the surface of the skin with an influx of warm blood. This can actually result in making the core body temperature lower, as it allows for easier heat exchange with a cold external environment. 
Story: Two people got stuck in a local  blizzard. Tom had a bottle of alcohol with him and drank it after he found some kind of shelter in the snow. Dan didn't have alcohol with him. 
Question: Which of the two people had a larger influx of warm blood near the surface of the skin?
Tom.

Background Paragraph: It would be very unadvisable to place a can of soup over a campfire without venting the can. As the can heats up, it may explode. The kinetic-molecular theory explains why. The air inside the rigid can of soup is given more kinetic energy by the heat coming from the campfire. The kinetic energy causes the air molecules to move faster and they impact the container walls more frequently and with more force. The increase in pressure inside may eventually exceed the strength of the can and it will explode. An additional factor is that the soup may begin boiling which will then aid even more gas and more pressure to the inside of the can. 
Story: A team of hikers split into two groups. Group Jones hiked north and camped there  overnight. Group George went east. Both groups made campfires and heated cans of soups. Group Jones didn't make holes in the cans, so the cans exploded. The others heated their soup cans the right way, by venting them first. 
Question: Which group's cans had the air molecules inside impact the container walls with more force?
Jones.

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?

Michael.
