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.

[Q]: Background Paragraph: Although some lipids in the diet are essential, excess dietary lipids can be harmful. Because lipids are very high in energy, eating too many may lead to unhealthy weight gain. A high-fat diet may also increase lipid levels in the blood. This, in turn, can increase the risk for health problems such as cardiovascular disease. The dietary lipids of most concern are saturated fatty acids, trans fats, and cholesterol. For example, cholesterol is the lipid mainly responsible for narrowing arteries and causing the disease atherosclerosis. 
Story: Greg is a doctor with the city hospital. Today, he is seeing two patients, patient A and patient B. Patient A maintains a high-fat diet, but patient B does not maintain a high fat diet. Greg is advising the patients how lifestyle change can improve their health. 
Question: Which patient would not have narrower arteries, patient A or patient B?
[A]: patient B.


[Q]: Background Paragraph: In the wiring of a building, the wires carrying the current in and out are different and never touch directly. The charge passing through the circuit always passes through an appliance (which acts as a resistor) or through another resistor, which limits the amount of current that can flow through a circuit. Appliances are designed to keep current at a relatively low level for safety purposes. The appropriate voltage and resistance in a circuit keeps the current in control and keeps the circuit safe. It is possible, however, for something to happen that causes the wire bringing the current in to come into contact with either the wire carrying the current out or the ground wire, thus causing what is called a short circuit . In a short circuit, some or all of the resistance is cut out of the circuit allowing the voltage to push a huge current through the wires. 
Story: Adam is playing a game on his computer. The wire plugging his computer into the wall is frayed and a bit of it is showing. One day he accidentally knocks over a glass of water and it spills onto the wire essentially making all of the wires in the cord touch eachother. There are large sparks and his computer completely shuts off. 
Question: Will the voltage pushed through a ciruit increase or decrease when the wire bringing current in comes into contactwith the wire bringing the current out.?
[A]: increase.


[Q]: 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 neutrophils on his wound, John or Keith?
[A]:
Keith.
