Answer
Brief Explanations:
In 1979, there was an energy - related major event in the US. The 1979 energy crisis was triggered by a drop in oil production in Iran following the Iranian Revolution. The creation of a US national bank did not occur in 1979. There was no second oil embargo in 1979, and the major oil cartel OPEC was formed earlier (in 1960).
Answer:
an energy crisis.
