Answer: Development of automobiles with lower nitrogen oxide and hydrocarbon emissions.

Explanation:

The 1990 amendment to the Clean Air Act (1963) discussed environmental problems such as acid rain, toxic pollutants, and the ozone layer. Large reductions in gas emissions were required to avoid acid rain, the regulation of toxic elements was strengthened, and some chemicals that were prejudicial to the ozone layer depletion were banned.
