Question

At the beginning of WWII, what action by Winston Churchill influenced Hitler’s strategy?

Answer 1

The answer is C: Churchill refused to negotiate.

Answer 2

This could be many things, but my main thought would be Churchill's first moves were against the Japanese rather than the Germans, Which allowed Hitler/Rommel to attack some of the British reserves in Africa.
But this might be different than what is in your history book, but I hope this helps
