B: The crisis was used as an excuse by the Reagan administration to artificially inflate the price of gasoline.
C: The crisis was engineered by the American oil companies in order to raise the price of a barrel of oil, and hence, gasoline.
D: The crisis was over as quickly as it began because the OPEC countries feared invasion by the industrialized West.
