B Correct answer
Explanation

The MAC is the concentration of a chemical in the air that can cause long-term health effects, such as cancer or respiratory problems.

Multiple choice

Which of the following is NOT a common health issue associated with urban living?

  1. Air pollution

  2. Obesity

  3. Mental illness

  4. Chronic diseases
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Obesity is not typically associated with urban living. In fact, studies have shown that people who live in urban areas are less likely to be obese than those who live in rural areas.

Multiple choice

Which of the following is NOT a common health issue associated with urban air pollution?

  1. Asthma

  2. Heart disease

  3. Stroke

  4. Healthy diet
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Healthy diet is not typically associated with urban air pollution. In fact, studies have shown that people who live in areas with high levels of air pollution are more likely to have unhealthy diets than those who live in areas with low levels of air pollution.

  1. Hearing loss

  2. Sleep disturbance

  3. Heart disease

  4. Healthy diet
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Healthy diet is not typically associated with urban noise pollution. In fact, studies have shown that people who live in areas with high levels of noise pollution are more likely to have unhealthy diets than those who live in areas with low levels of noise pollution.
