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.

Background Paragraph: Regions on the Earth's surface (or in its atmosphere) that are high above mean sea level are referred to as high altitude. High altitude is sometimes defined to begin at 2,400 meters (8,000 ft) above sea level.[5][6][7]

At high altitude, atmospheric pressure is lower than that at sea level. This is due to two competing physical effects: gravity, which causes the air to be as close as possible to the ground; and the heat content of the air, which causes the molecules to bounce off each other and expand.[8].
Story: There was a competition for who can get their yellow drone the highest into the air. Team A got it 2,551 ft. Team B got it 3,551 ft. Team C go it 4,541 ft. Team D got it 5,531 ft. Team E got it 10,521 ft. Team F got it 13,571 ft. Team G got it 14,581 ft. Team G won the contest and got a big gold trophy as the prize.
Question: What team got their drone into high altitude: Team B or Team G?

Ex Output:
Team G.

Background Paragraph: Demographic stochasticity refers to variability in population growth arising from sampling random births and deaths in a population of finite size. In small populations, demographic stochasticity will decrease the population growth rate, causing an effect similar to the Allee effect, which will increase the risk of population extinction. Whether or not demographic stochasticity can be considered a part of Allee effect is somewhat contentious however. The most current definition of Allee effect considers the correlation between population density and mean individual fitness. Therefore, random variation resulting from birth and death events would not be considered part of Allee effect as the increased risk of extinction is not a consequence of the changing fates of individuals within the population.Meanwhile, when demographic stochasticity results in fluctuations of sex ratios, it arguably reduces the mean individual fitness as population declines. For example, a fluctuation in small population that causes a scarcity in one sex would in turn limit the access of mates for the opposite sex, decreasing the fitness of the individuals within the population. This type of Allee effect will likely be more prevalent in monogamous species than polygynous species.
Story: Two small cities of identical population are both having elections this year. Although they have the same small amount of people, the city of Kilmar is experiencing demographic stochasticity while the city of Plano is not. Every time an election arises, both cities become very active with citizens coming out in droves to listen to the candidates speak at town hall meetings through the months leading up to the election.
Question: Which city's population will grow faster?

Ex Output:
Plano.

Background Paragraph: A mycorrhiza (Greek for "fungus roots") is a symbiotic association between a fungus and the roots of a plant. In a mycorrhizal association, the fungus may colonize the roots of a host plant by either growing directly into the root cells, or by growing around the root cells. This association provides the fungus with relatively constant and direct access to glucose, which the plant produces by photosynthesis. The mycelia of the fungi increase the surface area of the plant's root system. The larger surface area improves water and mineral nutrient absorption from the soil.
Story: Two gardeners started their planting season at the same time. Bill used mycorrizal fungi compost for the garden, while Hank used regular top soil. Bill was very happy with the harvest.
Question: Which gardener had more fungus with constant and direct access to glucose?

Ex Output:
Bill.
