Final answer:
The EPA indeed tests a small percentage of new vehicles each year to gather emission data, which helps calculate fuel economy and ensure compliance.
Step-by-step explanation:
The statement that the Environmental Protection Agency uses a few new automobiles of each model every year to collect data on pollution emissions is true. The EPA tests a limited number of vehicles — between 200 to 250 a year — which constitutes about 15% of new models. These tests are significant as they help calculate the fuel economy information provided by manufacturers, and also involve the random selection of two-thirds of the vehicles, while the remaining are chosen for specific reasons.
