Question

how did the united states respond to the crisis in west berlin in 1948 - 1949?
it withdrew its armed forces from west berlin.
it signed a peace treaty with the soviet union.
it insisted that east and west germany be united.
it organized an airlift to send supplies to west berlin.

Explanation:

In 1948 - 1949, the Soviet Union blockaded West Berlin. The US did not withdraw its forces (eliminating the first option). There was no peace treaty signed during this crisis (eliminating the second option). The idea of uniting East and West Germany was not a response to the immediate Berlin blockade crisis (eliminating the third option). The US organized the Berlin Airlift to supply West Berlin, which is a well - known historical event.

Answer:

It organized an airlift to send supplies to West Berlin.
