PROBLEM: Background Paragraph: 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. 
Story: Two teams of runners took part in a study about exercise. Red team ran 10 km in the heat, while Green team ran the same distance in the morning in cool weather. The Red team experienced more runners with health problems. 
Question: Which team had fewer runners with muscle weakness?

SOLUTION: Green.

PROBLEM: Background Paragraph: Alberta's electrical demand varies throughout the day and across the seasons. When individuals are fixing supper and using home appliances, demand for power goes up, as it does during heat waves and cold snaps. It tapers off during spring and fall. Like other mechanical devices, generators fail from time to time. If they are wind-powered, their output varies with the wind. 
Story: Tony is in charge of a power station in Alberta. He has been tasked with turning on and off generators depending on the demand for power. He has been ordered to try and be efficient as possible, turning off generators in low demand times, and turning them on in high demand times to satisfy needs. On Monday and Tuesday, Alberta saw record high temperatures, and on Thursday and Friday,  things cooled off for a more moderate and comfortable temperature. 
Question: Which days did Tony most likely turn on more generators?

SOLUTION: Monday and Tuesday.

PROBLEM: Background Paragraph: Recall that air pollution is due to chemical substances and particles released into the air mainly by human actions. When most people think of air pollution, they think of the pollution outdoors. But it is just as easy to have indoor air pollution. Your home or school classroom probably doesn't get much fresh air. Sealing up your home reduces heating and cooling costs. But this also causes air pollution to stay trapped indoors. And people today usually spend a majority of their time indoors. So exposure to indoor air pollution can become a significant health risk. 
Story: Two neighboring cities had very different health related problems. Twin city had increased air pollution, their people experiencing all kinds of respiratory diseases, while Pine city had problems with age related diseases. 
Question: Which city had more people exposed to outdoor pollution?

SOLUTION:
Twin.
