The political science test

The 3 1/2-hr. conference call brought together nearly two dozen of the nation's best minds on the subject of air quality -- and many of them were steamed. As the scientists of the Environmental Protection Agency's Clean Air Scientific Advisory Committee, they are rarely overruled on their recommendations about how the government should react to the latest and best research on the dangers of dirty air.
