what triggered the second oil shock in 1979?
○ reduced demand for oil
○ a revolution in iran
○ increased demand for oil
○ a shortage in the united states
done ✔

Explanation:

The 1979 second oil shock was driven by a major disruption to global oil supplies. The Iranian Revolution led to a sharp drop in Iran's oil production and exports, creating a global oil shortage and spiking prices. The other options are incorrect: reduced demand would lower prices, increased demand alone did not trigger this specific shock, and a U.S. domestic shortage was not the root cause.

Answer:

A revolution in Iran
