What was the Berlin blockade? What was the Berlin Airlift?

The berlin Blockade was one of the first huge crisis of the Cold War.  During the post World war 2, germany (the soviet union) blocked the Western Allies railway road and canal access to the sectors of Berlin under Western Control. The soviets offered to drop blockade of the Western Allies withdrew Deutsche Mark from west Berlin.

This was the first crisis of the post WWII Cold war. The Soviet Union blocked western allies from the section of Berlin under Western control. They responded with an organized airlift.

i believe it d) heterogeneous

the group i'm selecting: greeks.

a first group of greek immigrants came to the us in the 1850s. the second group came to america starting in the 1890s due to economic opportunities they didn't have back in their home caused by the hardships of ottoman rule. greek immigration was 90% male, many of them expected to work and return to greece after earning enough capital, but ultimately had to remain in the us after the greek genocide.
