I read this background article the other day: Millions of people in the world jog for exercise. For the most part, jogging can be a healthy way to stay fit. However, problems can also develop for those who jog in the heat. Excessive sweating can lead to electrolyte loss that could be life-threatening. Early symptoms of electrolyte deficiency can include nausea, fatugue, and dizziness. If not treated, individuals can experience muscle weakness and increased heart rate (which could lead to a heart attack). Many sports drinks can be consumed to restore electrolytes quickly in the body. I am facing a new situation today: Two teams of runners were training for a 10k. Team Y jogged early in the morning when the weather was cool. Team X started their training in the heat so many team members had problems sweating. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which team had fewer people that experienced fatigue?
----
Answer: Team Y

I read this background article the other day: During the Cold War, the Arctic became a place where the United States, Canada, and the Soviet Union performed significant research that has been essential to the study of climate change in recent years. A major reason why research in the Arctic is essential for the study of climate change is because the effects of climate change will be felt more quickly and more drastically in higher latitudes of the world as above average temperatures are predicted for Northwest Canada and Alaska. From an anthropological point of view, researchers study the native Inuit peoples of Alaska as they have become extremely accustomed to adapting to ecological and climate variability.[1] I am facing a new situation today: Two sister cities, located at different altitude, are affected differently by climate change. Bergen is at 60 degrees N, while Seattle is at 47 degrees N latitude. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which city experienced fewer temperatures above average?
----
Answer: Seattle

I read this background article the other day: When soil is flooded, hypoxia develops, as soil microorganisms consume oxygen faster than diffusion occurs. The presence of hypoxic soils is one of the defining characteristics of wetlands. Many wetland plants possess aerenchyma, and in some, such as water-lilies, there is mass flow of atmospheric air through leaves and rhizomes. There are many other chemical consequences of hypoxia. For example, nitrification is inhibited as low oxygen occurs and toxic compounds are formed, as anaerobic bacteria use nitrate, manganese, and sulfate as alternative electron acceptors. The reduction-oxidation potential of the rhizhosphere decreases and metal ions such as iron and manganese precipitate. Aerenchyma is a modification of the parenchyma. I am facing a new situation today: Two farmers are having a conversation at a bar about how their soil is doing. Jeff takes a sip of his beer and says that he just discovered that his soil is hypoxic. Brandon is trying to get the attention of the bartender so he can order another martini. Upon hearing Jeff's remark about his soil, Brandon states that the soil on his own farm is not hypoxic. Brandon is relieved when he notices the bartender is finally walking over to them. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Does Jeff's soil have more or less toxic compounds than Brandon's?
