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.

[EX Q]: Background Paragraph: Cholesterol has been implicated in heart disease for decades. Atherosclerosis is a disorder of the arteries in which cholesterol and other materials are deposited on the interior of the arterial wall. These deposits lead to the formation of plaques that can restrict or even block the flow of blood through these blood vessels (see Figure below ). A decrease in the flow of blood can lead to high blood pressure and a lowered oxygen supply to the heart muscle. A complete blockage of blood flow to parts of the heart (a heart attack) can cause significant damage due to oxygen deprivation, in some cases leading to death. 
Story: Two teams of researchers studied different diseases. team Alpha studied people with cholesterol, while team Beta studied people with Parkinson's disease. 
Question: Which team studied more people with restricted blood flow to the heart muscle?
[EX A]: Alpha.

[EX Q]: Background Paragraph: The Gaia hypothesis states that the biosphere is its own living organism. The hypothesis suggests that the Earth is self-regulating and tends to achieve a stable state, known as homeostasis . For example the composition of our atmosphere stays fairly consistent, providing the ideal conditions for life. When carbon dioxide levels increase in the atmosphere, plants grow more quickly. As their growth continues, they remove more carbon dioxide from the atmosphere. In this way, the amount of carbon dioxide stays fairly constant without human intervention. 
Story: A scientist with an interesting idea for an experiment begins building a dome. This dome will be completely cut off from the rest of the world. It will produce all of its own resources, breathable air, anything needed to sustain life, putting it into a state of homeostasis. 
Question: Given The Gaia hypothesis, would this dome be considered a living organism or non-living?
[EX A]: living.

[EX Q]: Background Paragraph: Ecologically, the expansion of drainage systems has had tremendous negative effects. Hundreds of thousands of wetland species experienced significant population declines as their habitat was increasingly fragmented and destroyed. Although market hunting within the Central Flyway was a contributing factor in the decline of many waterfowl species' numbers in the early decades of the twentieth century, loss of breeding habitat to agricultural expansion is certainly the most significant. Early maps of midwestern states depict many lakes and marshes that are either nonexistent or significantly reduced in area today. Channelization, a related process of concentrating and facilitating the flow of water from agricultural areas, also contributed to this degradation. 
Story: The Vista Corporation has decided that it needs to expand it's drainage systems to provide for its ever expanding campus. They have a couple of options to route the piping through, the most feasible being a wetlands area to the east, and an empty field to the west. City planners have given them the okay for either, but Vista Corporation is trying to explore which decision will have the least ecological impact on the area, as damaging the environment may have bad PR results for them. 
Question: Which drainage expansion project will more than likely do the least damage local wildlife, the empty field area or wetlands area expansions?
[EX A]:
empty field area.
