Answer

Brief Explanations:

The Clean Air Act aimed to reduce air - pollution from cars. Using cleaner - burning gas helps in reducing emissions. Making smaller cars doesn't directly relate to clean air. Requiring drivers to drive shorter distances is not a requirement of the act. Making electric cars was not an immediate requirement when the act was first passed.

Answer:

Cleaner - burning gas had to be used in cars.
