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: For example, your body has an internal thermostat. During a winter day, in your house a thermostat senses the temperature in a room and responds by turning on or off the heater. Your body acts in much the same way. When body temperature rises, receptors in the skin and the brain sense the temperature change. The temperature change triggers a command from the brain. This command can cause several responses. If you are too hot, the skin makes sweat and blood vessels near the skin surface dilate. This response helps decrease body temperature. 
Story: Recently, a man name Bob broke his leg, and has been commanded to stay inside and rest while it heals. His wife, Gretchen, has had to do most of the yard work, and it has been very hot outside. Bob has been watching his wife cut the grass and feels bad, noticing she looks tired, while he gets to sit inside in the air conditioning. 
Question: Which of the two most likely has their blood and sweat vessels dilated?
Example Output: Gretchen.

Example Input: Background Paragraph: So much rain falling so fast causes some of the damage from a hurricane. But a lot of the damage is caused by storm surge. Storm surge is very high water located in the low pressure eye of the hurricane. The very low pressure of the eye allows the water level to rise above normal sea level. Storm surge can cause flooding when it reaches land ( Figure below ). High winds do a great deal of damage in hurricanes. High winds can also create very big waves. If the large waves are atop a storm surge, the high water can flood the shore. If the storm happens to occur at high tide, the water will rise even higher. 
Story: Beach town was hit hard by the hurricane. Hill town was spared, being situated 50 miles south. the eye of the hurricane passed almost through Beach town. 
Question: Which town had less damage caused by storm surge?
Example Output: Hill.

Example Input: Background Paragraph: However, when going across a period from left to right, the atomic radius actually tends to decrease. Why is this so? Each successive electron is going into the same principal energy level as the previous one, so the total amount of occupied space does not really go up significantly. Additionally, because protons are also added to the nucleus as you go across the row, the pull of the positively charged nucleus on the negatively charged electrons increases. This tighter pull leads to a slight decrease in atomic radius. As a result, the atomic radii of the elements exhibit a periodic trend, gradually tends to downward, but with a sharp spike up whenever electrons are added to a new principal energy level ( Figure below ). 
Story: There are two elements, Zaxon and Barton. Zaxon is an element that is further left on the period, and Barton is on the right of the period. 
Question: Which element has a weaker pull between the nucleus and the electron?
Example Output:
Zaxon.
