Critical Reasoning

Los Angeles officials have determined that regulating carbon emissions from cars is the most effective way to deal with air pollution. Recently, the Los Angeles Department of Motor Vehicles decided to change local car inspection policies to only pass cars that demonstrate a lower level of carbon emissions than was previously accepted. Because there are so many cars on the road in Los Angeles, local government officials concluded that these policies will soon dramatically reduce air pollution in the city.

Which of the following, if true, most undermines the government officials' conclusion?

A. The average driver in Los Angeles drives for approximately 37 minutes per day.
B. There are more cars on the road than trucks or other motor vehicles.
C. In order for cars to meet the new standard, some vehicles will need to be fitted with a graphite layer filter, which seeps toxic material into the earth when thrown away.
D. Uninsured and unlicensed drivers will not partake in the inspection process.
E. The inspection policies will apply only to newly purchased cars, which comprise a small minority of Los Angeles traffic.

IMO - E
