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: Hepatitis B is a contagious virus that affects the liver, infection can last from a few weeks to a serious lifelong illness. Two different types of infection exist for this disease, "acute" and "chronic." Acute Hepatitis B is a short term illness that occurs within 6 months of exposure, Chronic Hepatitis B is long term and happens when the virus remains in the body. The younger the child is, the greater their chance of developing a chronic infection and this risk goes down as the child gets older. Approximately 90% of infected infants will develop a chronic infection.[3]. 
Story: A 1st grade classroom photo was held today. They all gathered by age.  Lawrence was the oldest. Nicholas was the 2nd oldest. Roy was the 3rd oldest. Benjamin was the 4th oldest. Bruce was the 5th oldest. Brandon was the 6th oldest. The last one was Adam, who was the youngest. They all looked handsome that day. 
Question: Who has a greater chance of developing a chronic infection: Benjamin or Adam?

Output: Adam.


Input: Consider Input: Background Paragraph: Surface temperature differences in turn cause pressure differences. A hot surface warms the air above it causing it to expand and lower the density and the resulting surface air pressure. The resulting horizontal pressure gradient moves the air from higher to lower pressure regions, creating a wind, and the Earth's rotation then causes deflection of this air flow due to the Coriolis effect. The simple systems thus formed can then display emergent behaviour to produce more complex systems and thus other weather phenomena.  Large scale examples include the Hadley cell while a smaller scale example would be coastal breezes. 
Story: Mark was visiting southern Africa as an exchange student. He was amazed by the beauty of Namib Desert, which is located mostly in Namibia. He kind of enjoyed the hot surface of the desert. Next to Namib desert is the grasslands of  Botswana. He noticed that the surface temperature was much lower there. 
Question: Which place would have lower surface air pressure, Namibia or Botswana?

Output: Namibia.


Input: Consider Input: Background Paragraph: Most chemical reactions within organisms would be impossible under the normal conditions within cell. For example, the body temperature of most organisms is too low for reactions to occur quickly enough to carry out life processes. Reactants may also be present in such low concentrations that it is unlikely they will meet and collide. Therefore, the rate of most biochemical reactions must be increased by a catalyst. A catalyst is a chemical that speeds up chemical reactions. In organisms, catalysts are called enzymes . 
Story: Mike is a biochemist, working for a science lab. Today, he has two organisms to investigate, organism A and organism B. He notices that organism A has enzymes, but organism B lacks enzymes. He needs to figure out how these conditions would affect the organisms. 
Question: In which organism the the chemical reactions would be speedier, organism A or organism B?


Output: organism A.
