Problem statement:

The Illinois Environmental Protection Agency conducts a research in which state officials want to find the type(s) of vehicle emissions testing in your community, the test procedures and results, what can you do if your car just failed an emissions test, and what the level of air pollution is in your community due to vehicle emissions.

You (at Davea) are asked to collaborate with other High School classes in DuPage County as well as with other individuals in your community to identify the current status of vehicle emissions testing in DuPage County, to analyze some results of emissions testing, and to predict the levels of air pollution in your county due to vehicle emissions.
