Question

what caused great britain and france to declare war on germany in 1939?
○ the appeasement policy
○ the invasion of poland
○ the nonaggression pact
○ the surrender of poland

Explanation:

To determine the cause of Great Britain and France declaring war on Germany in 1939, we analyze each option:

• "The appeasement policy" was a pre - war strategy to avoid conflict, not the cause of the declaration of war.
• "The invasion of Poland": Germany invaded Poland on September 1, 1939. Great Britain and France had guaranteed Polish independence, so this invasion led them to declare war on Germany on September 3, 1939.
• "The nonaggression pact" (Molotov - Ribbentrop Pact) was between Germany and the Soviet Union, and it was more about dividing Eastern Europe, not the direct cause of Britain and France's declaration of war.
• "The surrender of Poland" happened after the declaration of war, so it can't be the cause.

Answer:

B. the invasion of Poland
