TASK DEFINITION: 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.
PROBLEM: Background Paragraph: Circadian rhythms are regular changes in biology or behavior that occur in a 24-hour cycle. In humans, for example, blood pressure and body temperature change in a regular way throughout each 24-hour day. Animals may eat and drink at certain times of day as well. Humans have daily cycles of behavior, too. Most people start to get sleepy after dark and have a hard time sleeping when it is light outside. In many species, including humans, circadian rhythms are controlled by a tiny structure called the biological clock . This structure is located in a gland at the base of the brain. The biological clock sends signals to the body. The signals cause regular changes in behavior and body processes. The amount of light entering the eyes helps control the biological clock. The clock causes changes that repeat every 24 hours. 
Story: Marcus has a long day ahead of him. He woke up early, around 7 AM to start his day. For a research study he takes his blood pressure around 9 AM and continues on through his day. Around noon he takes his blood pressure again noting that it has increased a little. He takes his blood pressure one more time before going to bed around 10PM. 
Question: Will an animals blood pressure be at its highest in the middle of the day or at its lowest?

SOLUTION: highest.

PROBLEM: Background Paragraph: Following the utilitarian principle of seeking the greatest good for the greatest number – economic inequality is problematic. A house that provides less utility to a millionaire as a summer home than it would to a homeless family of five, is an example of reduced "distributive efficiency" within society, that decreases marginal utility of wealth and thus the sum total of personal utility. An additional dollar spent by a poor person will go to things providing a great deal of utility to that person, such as basic necessities like food, water, and healthcare; while, an additional dollar spent by a much richer person will very likely go to luxury items providing relatively less utility to that person. Thus, the marginal utility of wealth per person ("the additional dollar") decreases as a person becomes richer. From this standpoint, for any given amount of wealth in society, a society with more equality will have higher aggregate utility. Some studies[2][32] have found evidence for this theory, noting that in societies where inequality is lower, population-wide satisfaction and happiness tend to be higher. 
Story: Finland has one of the lowest economic inequality in the world. Finland's neighbor Russia has a different story. After the collapse of Soviet Union, Russia's economic inequality soared to the point that it has now one of the highest economic inequality in the world. John and Keith are residents of Finland. While John is rich, Keith is not so fortunate - he is poor. Similarly, David and Greg are residents of Russia. While David is rich, Greg is in poverty. 
Question: Would people in Russia most likely be more happy or less happy than people in Finland?

SOLUTION: less happy.

PROBLEM: Background Paragraph: The body's second line of defense against pathogens includes the inflammatory response. If bacteria enter the skin through a scrape, the area may become red, warm, and painful. These are signs of inflammation. Inflammation is one way the body reacts to infections or injuries. Inflammation is caused by chemicals that are released when skin or other tissues are damaged. The chemicals cause nearby blood vessels to dilate, or expand. This increases blood flow to the damaged area, which makes the area red and slightly warm. The chemicals also attract white blood cells called neutrophils to the wound and cause them to leak out of blood vessels into the damaged tissue. 
Story: John and Keith were playing football - the game was rough to say the least. They both got hurt. After the game they went to see the sports physician for a check up. The physician found that John had inflammation, but Keith didn't have any inflammation. 
Question: Who would not have dilated blood vessels near the wound, John or Keith?

SOLUTION:
Keith.
