Answer:
In the 1930s, the United States abandoned the gold standard because the government wanted to rapidly expand the money supply in response to the Great Depression.
Explanation:
The Gold Standard monetary system was abandoned during the years after the Great Depression of 1929 to prevent prices and wages from falling in response to a general reduction in global demand, so that adjustments fell on the total amount of employment. Under these conditions, the depreciation of the exchange rate (that is, the abandonment of the pure gold standard) was considered "less painful" (in order to reduce exports). This prevented the reduction of wages, especially since the pressure of the unions imposed this kind of policy in some way. And all this in addition without taking into account that all countries, sooner or later, would adopt the same policy, resort to devaluation, with which the destruction of employment for years was inevitable.
They are called Calvary.

The Iran hostage crisis <u><em>affected negatively the American opinion of President Carter </em></u>to the point that it probably cost him his second term as President of the United States. On November 4th, 1979, a group of Iranian students stormed the U.S Embassy in Teheran taking more than 60 Americans hostages. This action was a direct result of President Carter's decision of allowing the deposed Shah the possibility of getting medical treatment in the United States.
The students set their hostages free on April of 1981, 444 days after the crisis began and just hours before new elected President Reagan delivered his inaugural address.
