Explanation:

In the context of Cold War history, the Soviet Union established the Berlin Blockade (a blockade) to prevent supplies from reaching West Berlin. The key event here is the Berlin Blockade, so the term that fits is "blockade" (or in the context of the dropdown, likely the option related to the Berlin Blockade, but since we need to fill the blank, the correct term is "blockade" or more specifically "Berlin Blockade" but the blank likely expects "blockade" or the specific term for the action.
