Example 1
Turn chronology into causation
Prompt: Explain one reason why tension increased during the Berlin Blockade. Step 1: Name the event: Stalin blockaded land routes into West Berlin in 1948. Step 2: Explain the cause of tension: the Western allies saw this as an attempt to force them out of Berlin. Step 3: Add consequence: the Berlin Airlift showed the West would resist Soviet pressure, deepening the division between East and West. The mark comes from the explanation chain, not from the date alone.
