Barrier built in August 1961 that surrounded West Berlin to isolate it from East Germany; opened on November 9, 1989. Which option describes this?

• A. It symbolized the Cold War division of Europe
• B. Barrier built in August 1961 that surrounded all of West Berlin to isolate it from East Germany
• C. It was opened on November 9, 1989
• D. It was known as the Berlin Blockade

Answer: (B)

The barrier described is the Berlin Wall. Built in August 1961, it surrounded West Berlin to isolate it from East Germany, preventing East Germans from fleeing to the West. It stood as a stark symbol of the Cold War division of Europe until it opened on November 9, 1989, when border crossings were opened and people could pass freely. This description directly identifies the barrier by its construction date and its opening date, making it the best match. While other statements touch on related ideas—the wall’s role as a symbol of division or the earlier Berlin Blockade—they don’t combine the exact construction and the 1989 opening in a single description.
