Which of the following is most likely responsible for the indoor air pollutant shown in the graph?

A. Cracks in the basement foundation

Which of the following best describes the process shown in the diagram above?

B. Less-dense, warm air creates a temperature inversion between more-dense layers, trapping pollutants near the ground.

Which of the following claims is best supported by the data shown in the table?

C. Isoprene's contribution to ozone levels in Berlin was greatest in July of both years.

Which of the following best describes the relationship between variables in the data table?

C. Ozone maximum is correlated to average and maximum temperature.

What is one potential impact of increased noise pollution in national parks that is supported by the article?

C. Prey populations are likely to increase in national parks because predators have a decreased ability to hear prey sounds.

Which of the following is the most likely reason for the trend shown in the graph of fluctuating indoor radon levels over the course of a year?

C. Radon levels tend to increase in the colder months because of the difference in temperature inside and outside the home, which creates a vacuum pulling radon into the home at a higher rate.
